Barotrauma Enhanced Performance Project(Project EP)

Brief desc:
This mod heavily modified original Barotrauma/LuaCsForBarotrauma code to improve performance. Multi-thread and multi-core were introduced.
This mod itself provides built-in LuaCs support and a built-in server performance monitor

All works based on
Lua For Barotrauma

Note: due to tech issue we cannot release any client for now but a server executable is available.

How to use:
For regular players:
Subscribe, download and load this mod -> Host server via main menu -> select ServerExecutable -> Barotrauma Enhanced Performance Project - DedicatedServer.exe
For server hosts:
Subscribe, download this mod -> copy-paste everything in ModDir/Binary into your server folder -> remove workshop.txt -> Start Server

What will this mod do:
Improve CPU useage, use more threads and cores. You will expect way less pull-backs and much more smooth game experience.

Note: All tests were conducted in heavy duty servers, using TSM, JiuZhou Arsnal, NT(with many expansions), EW, DDA, EK, etc. All servers shows significant improvements in performance and overall in-game experience

What you may experience:
Improved experience in servers using Project EP executables(in most cases)
Server crashs(very very rare)

If crashed/issues found:
Goto Github(link below), Issues -> New issue
Upload your crash report/what you experienced with a brief desc on what you were doing at the moment of crash/issue happened.

It's out now

[last burrow]

So far seems to just make game run worse

Tested with berrila full of items+a bit of spawned bots.

Both when hosted from ingame(character moved away from bots so gpu isnt loaded by them) and as headless it mostly just increases load on my cpy by 30% on all cores

Vanilla lua hosted in game

With this hosted in game

Vanilla lua dedicated

With this dedicated

Dedicated test was done without anyone on server as i closed client game itself after starting round annd let it settle

At least code wise this doesn't appear to be malware

[slender grove]

A high CPU useage is expected

bcuz we are using more cores and threads

and we are running on servers on PC over 4 cores

if you are worring about malware go check github

[last burrow]

Barotrauma was already running on 4 cores as can be seen in screenshots with normal lua executable

[slender grove]

Yes, but servers does NOT

[last burrow]

adding this mod just increased cpu usage on all cores while game was still 60 tickrate capped

[slender grove]

if you run only a DS you will see only one core was running

What we are doing is completely server-side and for now does not include CL

[last burrow]

Also have a screenshot for that above, yes it was mostly loading one core with some chaff on the rest but adding mod didn't decrease load on that one core just increased load on the rest

[thick storm]

If your server is less than 8 cores, the results may not be ideal

[last burrow]

If you dont have good cpu your performance
would be bad

truly optimisation classic

i would love to see someone do comparison on a 8 or 16 core cpu

[slender grove]

Have you ever checked TPS

[last burrow]

average 60 on both

cpu wasn't maxed in any of the tests

[slender grove]

For now we are hard-coded max thread counts, active work is being conducted

so low-end stuff may not function as you may expected

Cores are automatically assigned so we did not know what exactly what was happening

[slender grove]

The issue was, even if you owns a good CPU you still got a terrible performence

[slender grove]

Clarification:
For now in heavy-load servers that applied this all reported significient improvements in drag-backs.
These servers are using high-end CPUs because these heavy-load servers are expected to face heavy single-core load due to nature of Barotruama DS.
We did not have abaility to run tests on low-end CPUs because we dont have one on standby.
If you are running on a low-end CPU please be advised:
This mod may not perform as the same as our test sapmles.

For CPUs that has E/P cores:
We recommend running this on E cores and please try not use P cores
E cores are born for heavy duty but P cores are not.
Combining P and E cores may cause extra performence issue, eg. sudden TPS drop, due to we are using auto core assignment.

The conclusion:
Yes we have seen improvements on high-end CPUs.
No there are not enough evidences that shows there are performence improvement but we can see CPU useage was raising.

[last burrow]

Dont take this personal, optimization mods are just cesspool of malware and ai slop nowadays on workshop so i dig into them to keep people from being exploited thru them

[last burrow]

Btw E cores are not any different from P cores aside from running at lower clocks. They are usually just fused off normal cores which didn't pass quality control to run at full clock

They are efficient for the manufacturer

That does technically mean they use less power indeed

[slender grove]

That's alright 🙂 your comment are correct because we did not think about everything
and when you asks about this we made few mistakes on version management(confusing vm) so that's the reason we (maybe) used some aggerrsive attitude

[thick storm]

sad

[thick storm]

I see, so we need to respond promptly to community questions, and sometimes we need that feedback, even if they don't meet our expectations

[slender grove]

SITRIP:
Currently working on CL. Main bottleneck is rendering

[last burrow]

are you trying to do the thing Evil suggested with buffering all spritebatch calls into separate thread and rendering one tick later?

[slender grove]

Not decided yet. Probabily we need to update XNA 2.0.4 to XNA 4.0. The renderer itself seems thread-safe

[thick storm]

Obviously, we haven't

[slender grove]

According to our test, multi-thread did nothing on FPS, still investigating

[thick storm]

We think this may help improve the performance on CL.

[slender grove]

For now just getting started

[last burrow]

baro runs gpu unlimited(if no fps cap) in free time between ticks, so its not actually tied to tickrate

[slender grove]

We cant tell what to do right now. We are facing a out-dated physics engine and out-dated XNA framework. Still need time to figure out what we can/need to do.

[cinder bramble]

we need request official to get an upgrade of the XNA version to 4.0

[amber sierra]

I can test this on my 9800x3d if needed 👍

[slender grove]

Probably we will have to do it by ourselves

[slender grove]

That's unnecessary but if you want you can still share your serverlog on github

[trail fulcrum]

miscommunication here, Ydrec was referring to another mod.

[twilit badger]

how is the progress

[slender grove]

CL is on its way but we are having difficulties. SV has some issues causing crashes but most of them have been identified and will receive a fix ASAP

[serene thorn]

So for SP this mod makes no difference?

[slender grove]

So far it does NOT work in SP. We are facing difficulties when deal with CL project.

[trail fulcrum]

wouldn't SP not require a performance mod since the server is just hosted on your machine thus how fast it (the server) runs depends on how fast your PC is?

[slender grove]

CL pf is still recommended because we did nothing to CL side so far, which means rendering is limited by CL update

[amber sierra]

is using the EP dedicated server ServerExecutable all we have to do for peak improvement? or would hosting it using the start server external to baro be better?

[crystal grove]

the testing environment was a Windows VM on a PVE platform, where the 12 allocated vCPUs represent 6 physical P-Cores plus their hyper-threaded logical processors.

[slender grove]

We are still investigating an issue causing low CPU useage

[slender grove]

They are the same. But i personally recommeded running it over a dedicated machine if you dont have enough RAM/CPUs so it wont take up your Game's resource, vice versa

[slender grove]

Issue resolved. Please update to OBT/1.0.4

[slender grove]

welp got a typo 🙁 will fix
