Can't Join or Host R2B4 (work around created, since replaced Computer) | GTFO | Page 1

gloomy shuttle Dec 8, 2022, 6:05 PM

#

When I'm host, all clients are booted to main menu during loading.
When I'm Client, I get stuck in a infinite loading screen on myside, on every one else's screen I have disconnected, including hot joining

This only happens with R2B4, No other missions have gave me this problem. I have properly been able to play other missions since first encountering this issue

The Issue as I understand it right now :

Issues found with the Checksum while entering the level

After some testing and comparing the logs of the failed checksums, we found that under the XXHASH section, my hosting would get a different LateGeomorphScan number then client, and the same deal if I was client (I would have a different number as host)

As of now I Believe the issue is caused by AMD FX 83 Series CPUs, they may be mishandling a calculation during the generation of the level, which would cause a difference in the checksum

additionally, 2 people using the same series of the offending CPU can join each other, which for a checksum error is extremely odd

Notes:
Not Using a VPN
I'm using a ethernet cable
Using a different computer on the same network works

Things I already tried:
Restarting GTFO
Verifying game files
Reinstalling GTFO
Joining a new lobby
Hosting a new lobby
Restarting steam
Trying to join with different people
Updating my GPU drivers
Restarting my computer
Loading the level first in single player, then trying to join a multiplayer match
Deleting %APPDATA%..\LocalLow\10 Chambers Collective\GTFO
Turning off my firewall
Shutting down Malwarebytes anti-virus
sfc /scannow
Using Regedit to nuke GTFO from the registry, and then nuking appdate files and then reinstalling
Nuked Modman
joining a different level with a fog Turbine and Disinfect station (joining R2C2 plus R2D1 worked)
plugging in a controller (we found something in logs)
Resyncing Windows clock
Making sure Steam reinstalls the entire game

#

Try deleting the GTFO Folder in %APPDATA%..\LocalLow\10 Chambers Collective

#

When you did that, open the game again and it will create a new gtfo folder, then try to join

gloomy shuttle Dec 8, 2022, 7:11 PM

#

violet canopy Try deleting the GTFO Folder in %APPDATA%\..\LocalLow\10 Chambers Collective

is key binding saved here? if so which folder so I can try to preserve it

violet canopy Dec 8, 2022, 7:12 PM

#

Yeah, your config is saved there. You can rename the folder to something like GTFO.bak and first see if that allows you to join

#

If it does, either redo your keybinds or try replacing the files

gloomy shuttle Dec 8, 2022, 7:13 PM

#

alright

gloomy shuttle Dec 8, 2022, 7:21 PM

#

violet canopy Try deleting the GTFO Folder in %APPDATA%\..\LocalLow\10 Chambers Collective

did not fix the issue

violet canopy Dec 8, 2022, 7:22 PM

#

Hmm... if it's only this one level only thing I can think of that you can try is reinstalling the game

#

Verifying game files fixes most problems, not all. Some can only be fixed by a complete reinstall

gloomy shuttle Dec 8, 2022, 7:23 PM

#

I did already reinstall the game

violet canopy Dec 8, 2022, 7:23 PM

#

Oh.

#

Ah, missed that in you list

gloomy shuttle Dec 8, 2022, 7:23 PM

#

all good

violet canopy Dec 8, 2022, 7:24 PM

You're not using a vpn or anything else I assume

Can't Join or Host R2B4 (Not solved)

violet canopy Dec 8, 2022, 7:29 PM

#

Looked if someone else had this problem in the steam forums but nope

gloomy shuttle Dec 8, 2022, 7:29 PM

#

I do know of someone else

#

they brought it up in #gtfo-related-questions

violet canopy Dec 8, 2022, 7:30 PM

#

Exact same as you?

gloomy shuttle Dec 8, 2022, 7:30 PM

#

Preelexo

violet canopy Dec 8, 2022, 7:30 PM

#

I see.

#

So if you join a lobby set to R2B4 it won't even load the lobby?

gloomy shuttle Dec 8, 2022, 7:32 PM

#

the lobby loads

#

dropping down into the mission is when the connection issues happen

violet canopy Dec 8, 2022, 7:33 PM

#

At the start or when it should give you the mission briefing?

gloomy shuttle Dec 8, 2022, 7:33 PM

#

during the cage drop

#

after a little bit

#

past the skippable intro

violet canopy Dec 8, 2022, 7:36 PM

#

Hmm... sorry then I am out of ideas for now, if I remember some other stuff I'll let you know but I'm also stumped rn

gloomy shuttle Dec 8, 2022, 7:36 PM

#

alright, thank you for the suggestion

#

you know of anyone else that can help?

violet canopy Dec 8, 2022, 7:40 PM

#

Sadly not, wasn't that often in technical support as there was a lot of chaos because it was unstructured but I gave it a shot since it's in forums now so I don't know anyone directly who was active in the channels

#

I think someone might reply with a suggestion over time

gloomy shuttle Dec 8, 2022, 7:40 PM

#

kk

gloomy shuttle Dec 8, 2022, 8:14 PM

#

Turning off my firewall or killing malwarebytes didn't help

#

hey @jade finch, got any ideas?

high falcon Dec 8, 2022, 9:37 PM

#

I don't know for sure if this will help, but you could always try booting in safe mode and trying to run the game then

#

Might take some finagling, but since it seems like a very localized issue to a couple people, there could be some background program conflicting with netcode specific to the level

violet canopy Dec 8, 2022, 9:39 PM

#

Windows won't load the GPU drivers in safe mode

#

Also drivers like directx or net framework will probably not work as they are not supposed to run in safe mode

gloomy shuttle Dec 8, 2022, 10:27 PM

#

high falcon Might take some finagling, but since it seems like a very localized issue to a c...

if that is the case, I think it would be better to find the offending program is question

#

the issue is I'm not running any notable programs outside of Discord, steam and GTFO itself

#

and firefox

#

if it was firefox or Discord, I think we would have way more people bringing it up

high falcon Dec 8, 2022, 10:31 PM

#

Hence it might be a background program

gloomy shuttle Dec 8, 2022, 10:31 PM

#

I looked over

high falcon Dec 8, 2022, 10:32 PM

#

Maybe a hardware monitor or something of the like
I'm just spitballing here, honestly no clue if it could be the offender

gloomy shuttle Dec 8, 2022, 10:32 PM

#

what you mean by hardware monitor

#

Like Kiryu said, safe mode would mean all sorts of things would not work, I think it would be harder to make the game run under those conditions

#

I just asked the Community manager what game logs could be helpful to us

#

we'll see if we get a response

high falcon Dec 8, 2022, 11:10 PM

#

Fair, game logs will likely give the answer

fiery grotto Dec 9, 2022, 4:14 AM

#

Usually logs have the name of the player with date

Unity logs have the name player and player prev and are stored for 2 sessions

Thought of something else that might be worth trying. Go to your main steam folder and select everything except for "steamapps", "userdata" and "steam.exe" and move them somewhere else while testing. Run steam.exe and it'll download all files again. Then try again.

#

It could be a problem with a steam connection manager file. Was just something that came to mind again that you could try, but well, it's kind of an odd method but who knows.

foggy spear Dec 12, 2022, 9:03 PM

#

it's obviously a networking issue

gloomy shuttle Dec 12, 2022, 9:03 PM

#

it's the only link

#

it's a failed Generationcheck sum

#

rn leading theory is a rounding error during level gen

foggy spear Dec 12, 2022, 9:06 PM

#

hmm, I think I've seen that checksum error before

gloomy shuttle Dec 12, 2022, 9:08 PM

#

If your using a FX 83 series CPU, please say so in this post. We would like to know if you can connect to R2B4 with people with this issue

#

the issue is when failed checksums happens

#

they usually fail in different ways

#

two failed checksums almost always never the same

#

expect for the fact in this case they are

#

they both failed in the same way

#

thus the machines with the issue were able to join each other

foggy spear Dec 12, 2022, 9:15 PM

#

afaik, generation checksum errors will pop up if your game files differ from the ones the host have

#

The only things I can think to fix that in terms of the vanilla game are verifying the game files, or reinstalling the game

#

it would be extremely weird that you two have corrupted, working files though

gloomy shuttle Dec 12, 2022, 9:19 PM

#

look at my post

#

I tried all of that and more

#

we are both generating the level in the wrong way in the same way

#

this is extremely weird

#

@jade finch what CPU do you have

gloomy shuttle Dec 13, 2022, 4:19 PM

#

violet canopy Dec 13, 2022, 4:46 PM

#

So, so far inly people that habe an AMD CPU have this issue?

#

Or rather, AMD FX CPUs

gloomy shuttle Dec 13, 2022, 4:47 PM

#

specifically AMD FX 83 series

#

that and only the people that stated their CPU

#

so far

swift pecan Jan 1, 2023, 10:44 PM

Someone in my lobby has the exact same issue with AMD FX 63 series

#

@prime vortex

gloomy shuttle Jan 2, 2023, 4:07 AM

#

2nd case I have seen this happen with FX 63 series

#

@swift pecan Thank you for the report

swift pecan Jan 2, 2023, 4:18 AM

#

Hope this helps clear some stuff as this issue is reproducible on other setups

(We then played another map and had no such problems, so I guess r2b4 truly is special)

gloomy shuttle Jan 2, 2023, 4:19 AM

#

1st case I have seen it for prosperity

#

the way b4 generates causes something to be different on select CPUs

#

and since a check is made to make sure everything is the same, the check fails

#

which cause clients not matching host to be booted

#

if you can get JeGERdiah to join a match with me later, I would like to test connection with me and them

#

I was able to join someone with the same issue which is super weird for a checksum fail

#

but they had the same series CPU

#

I have a FX 83 Series

It is absurd that a Dev hasn't even addressed this post yet given so much has been investigated and made evidently clear.

gloomy shuttle Jun 13, 2023, 7:13 AM

#

I imagine because I brought it to them

#

And considering the issue, the lack of new info from them is likely because they have not found any solutions

#

It's likely base instructions on very specific CPUs having oddities causing a rounding error

#

I was warned a while ago a solution might not be found

#

The devs know

And sadly it might end at that if they have no luck fixing it

Hey me and some friends have gotten back into GTFO after a really long time and one of my friends ran into this issue, everything that has been mentioned tracks, he has an FX 83 series CPU as well, we prefer doing stuff together in terms of GTFO so I'm trying to look into potential options that haven't been mentioned (if they have been mentioned already I really do apologize) but somethings that I can think of:

Running GTFO as an admin
updating the processor drivers or reinstalling them

There is a potential theory I have but I don't know what the fix would be which is:

Potentially a driver installation required in the FX 83 and 63 CPU's are "defensive" in that they're refusing to load something

#

If I can have my friend test some things whenever he gets the time I will but wanted to throw out somethings here to hopefully get a fix for everyone soon

gloomy shuttle Jul 16, 2023, 6:33 AM

#

No testing with drivers has taken place but I doubt it will solve the issue

#

As far as I'm aware, we have zero examples of the CPU generating the level correctly

#

And I can think of at least 4 examples from 4 separate fx 83 series cpus

#

On top of my head

#

You are welcome to try, knowing for sure if drivers will or will not solve the issue is useful info to have

gray sandal Jul 16, 2023, 6:39 AM

#

Yeah if my friend gets the time I'll test it with him

gloomy shuttle Jul 16, 2023, 6:39 AM

#

Realistically thou, you might want to look into alternative means

#

Such as your buddy using a different comp

#

Or regrettably replacing the CPU

#

The devs might fix it

#

But no means 100% going to happen

#

I wish I had a good answer for you, best of luck with the driver experiments

tyty will update if I find anything

swift pecan Jul 16, 2023, 7:02 PM

#

That would be rad if it was "just" a CPU microcode problem

gray sandal Jul 20, 2023, 1:42 AM

#

Update tried it unfortuantly didn't work I also tried having my friend run GTFO with -USEALLAVAILABLECORES command and run as admin and still nothing same error happens

gloomy shuttle Jul 20, 2023, 7:42 AM

#

Thank you for checking at least

#

If you want to do the level together, you have some options, none of them great

#

If your buddy has a different CPU or machine he can use to play the level, that would work

#

And for some reason you have the same CPU laying around, that would also work

#

2 people with the offending CPUs can join each other, at least with the fx 83 series

#

Sadly the only other option is skipping the level for the time being

#

Whatever you do, best of luck

#

Have any of the affected machines been overclocked?
And did anybody try increasing the voltage?
Those old AMD CPUs sometimes need a little more voltage to be stable
You can also try increasing the memory voltage slightly

#

also, anything useful in event viewer when this happens, like kernal errors?

gloomy shuttle Aug 9, 2023, 7:44 AM

#

When I had that computer, I didn't encounter any similar issues with anything else with my ~8-9 years of using it

#

@opal tapir this leads me to doubt anything would change if the over clocks happened, but if someone is willing and able, it should be tested

#

I have since parted out that computer

All of those levels are Storage environment

gloomy shuttle Sep 30, 2023, 8:35 PM

#

Isn't most or all of R1 storage?

#

None of those levels had the issue

opaque folio Sep 30, 2023, 8:38 PM

#

gloomy shuttle Isn't most or all of R1 storage?

r1a1,b1,c2 so half of r1

#

But I mean, it doesn't change that r2b4,r4a2,r6d3 are all storage (r6d3 I think it's storage,dig site, refinery same for r4a2)

gloomy shuttle Sep 30, 2023, 8:39 PM

Bit of a strange version of this issue, but we're having the same issue with R2B4 on an M2 Pro Macbook running the game via Apple's game porting toolkit (an x86 DX11 to ARM Metal translation layer)
all the other levels load fine, just like everyone else

#

It's not running on a supported platform, granted, but it's definitely a "you have a wierdo CPU" bug

#

given every other level we've tried from R1 to R7 has run fine through the translation layer on the unsupported platform

#

Unfortunately having read through the various threads about this bug it'll probably never be fixed

Sorry you have been affected. For those levels, does this also happen with the general public? And if so who is the one having issues with other people?

gloomy shuttle Dec 7, 2023, 10:57 AM

#

FX6300 is best to my knowledge affected in a very similar way to FX8300

#

I restrained myself to say affected in the same way since we have not tested if a user using Fx6300 can connect to another user with a fx6300

#

On that note, I am curious if a user with a fx6300 can connect to a user with a fx8300

Can someone pin this, just so it's easier to remember what levels are having this issue

opaque folio Dec 7, 2023, 11:40 AM

#

I think R3C1 also has that issue but I could be wrong, again, interesting to notice that those are all "Storage" environment levels (precisely, R4A2 is storage/dig site/refinery and R4C3 is storage/dig site)

gloomy shuttle Dec 7, 2023, 11:43 AM

#

Does all levels we know for sure has the issue storage/digsite

#

Or does one of the levels not have dig site

opaque folio Dec 7, 2023, 11:44 AM

#

R2B4 is only storage I'm pretty sure

gloomy shuttle Dec 7, 2023, 11:44 AM

#

Yeah that's right

opaque folio Dec 7, 2023, 11:44 AM

On the other hand most R1 levels are storage and they dont have the same issue, R1A1, R1B1, R1C2

Haven't tried with the public, just the two of us. We can each load solo just fine, but when either of us is host the other person gets kicked to rundown select after some load time in the elevator and cannot rejoin the party

gloomy shuttle That hallway leading to the 2 possible turbine sites is storage?

Yes it's partially like the A room of the zone with HSU in R1A1

robust pumice Feb 17, 2024, 8:22 PM

#

So are people with an 8320 or fx series CPU just condemned to either solo the level with bots or change their CPU? Cause there's at least one or multiple levels for every rundown apart from R1 and I believe R3 that can't load

You and the guy above (or anyone else with an AMD FX processor) can play these levels together I think. Otherwise you'll have to complete them yourself. Comprehensive list is: R2B4 R4A2 R4C3 R5D1 R8E2

Two people with the exact same CPU can play the level together iirc. I'm not sure if different AMD FXs can, however.

Me host. Friend send into menu....

Friend with Intel(R) Core(TM) i5-9500F CPU @ 3.00GHz 3.00 GHz

Maybe trouble in something different?

If FX guy hosts, everyone that doesn't use that CPU gets kicked

gloomy shuttle Feb 20, 2024, 9:57 AM

#

The issue is those CPUs are generating a different check sum

#

As a rule, client that don't match the host's check sum gets kicked

Can't Join or Host R2B4 (Unfixed, some closing details needed)

#

With the wrap up of GTFO's dev cycle and the fact this bug is likely never going to be fixed, I'm going to gather up some details about this bug and post it anywhere where people could look to see what could be causing them this issue. That way in the future if people encounter this bug, they can hopefully easily get answers, as grim as those answers are.

#

one thing I don't know off the top of my head is a exhaustive list of what levels are effected

#

If someone can provide them, that will be extremely helpful.

#

R2B4, R4A2, and R4C3 are the levels I know that are having this issue

#

but idk if other levels past that are effected

#

the PC I had this issue with originally was parted out quite awhile ago, so I can't test this myself

#

if you have a FX 6300 series or a FX 8300 series, you have this issue

On the other hand I think R5D1 has very few zones that are storage

@turbid oar can we make this a known issue with a modded patch?

It's a known bug where people with certain AMD FX CPUs fail to load levels correctly and thus can't play with anyone that does load the level correctly

a example of a level with this issue is R2B4

#Can't Join or Host R2B4 (work around created, since replaced Computer)

The Issue as I understand it right now :

additionally, 2 people using the same series of the offending CPU can join each other, which for a checksum error is extremely odd
