why the fuck would you pay this much
You really want to play video game with cheat?

Its not even hard to code that shit

What happened now?
the tl;dr is that an i2c read to get the chip id of the display driver isn't managing to happen

uuuuuh
faint sandal
Its not even hard to code that shit
so that's not entirely true - evasions are genuinely difficult and there aren't too many DMA devs
rough bloom
and the thing that they wanted to do is stupid
I think they would disagree

at this point you can just hire a pro player to do it for you for cheaper

Server side validation is the way. If someone is doing something that u know cant naturally happen then u just block it
opaque wharf
thank you kind rubber duck
Looking at this diagram, it is unlikely that the SPI is in the same ribbon cable
rough bloom
I don't do client side anticheats they are a joke
part of the earlier conversation was how server-side anticheat is even more of a joke somehow
silent cloak
Yeah thats just objectively wrong
Ur trusting the client to do the work for u
The very end thats trying to manipulate inputs
opaque wharf
The signal integrity for those differential would be too compromised otherwise
rough bloom
Yeah thats just objectively wrong
idk reality seems to disagree so far since everyone is still using client-side stuff

Because its cheaper

Uhh they are BGA. So yeah, probably not those

It may not be a vram
They are also near the ribbon connector

those are two separate chips, skhynix h5tq2g63ffr pbc 535r <different code between both chips>

Ahh, skhynix is defo a RAM

Or at least flash storage
trim valve
that was why I thought it was either ram or flash lol

Yeah. You need to find a chip without any leads (because BGA) and in the size of 4.5mm or 7mm
If you can't find it, then you need to actually disassemble it

It is what it is

UE5
UE5 isnt that bad if you know how the effects work and with that can decide what you should use and what you shouldnt use, or how you should use them
olive sable
cuz if you blindly enable settings it doesnt end too well
silent cloak
Except the part where its built like ass on the rendering end
olive sable
well yes, but actually no
olive sable
UE5 im not even gonna get into lumen and nanite cuz im not a big fan.
a large percentage of the perfromance issues come form those
olive sable
then you have the various different shader effects, of which most rely on some type of blurring, ussually TAA
even the raytracing depends on TAA in the end
silent cloak
Its so badly done
olive sable
those i can agree are bad
silent cloak
Their noise methods are horrible in their renderpipline which is part of why it looks so horrible during ghosting
Because its a static noise pattern often instead of something like blue noise
Which isnt that expensive to compute
olive sable
but besides that a lot of the issues is on the engine for not having stuff enabled by default, and on the dev for not enabeling it
like reusiing bitmask textures
silent cloak
Yeah
Its built for screenshots
They dont change the rendering settings often either so alot of games look exactly the same lmao
olive sable
a lot of the amateur games on steam you will see will have been made with UE5 and perform worse than satisfactory while also looking a lot worse
silent cloak
Mostly because of the filmic tone mapper
And the ghosting
Instant giveaways for the engine
olive sable
its not that the engine cant handle making great games, its that its hard to do so
silent cloak
It let's u get away with being lazy
And hiring people who dont know programming
Which yeah is good for companies but sucks for the consumers
Epic did blame game devs though for performance but thats only partly
From last year
olive sable
its easy for both sides to blame eachother
silent cloak
Shows u how big of an issue it is though
olive sable
"this should be on by default"
"you should ofcourse enable gpu instancing for this dum"
silent cloak
I could bet my kidneys that it would improve if they killed off blueprints

satsifactory gets me 1440p 200fps rn on high settings on my 7900xtx.
but they dont use lumen, the dont use virtual shadow maps, there's is aggresive culling that doesnt use nanite, the amount of nanite they do use is highly limited
silent cloak
They also have floating point bugs that make belts look horrible sometimes
olive sable
havent encountered that
silent cloak
olive sable
i always thought that was DLSS
silent cloak
Epic wont decouple it properly from TAA (they think nvidia tastes so good)
Disabling one of those 2 will cause issues generally
olive sable
huh
silent cloak
If u disable global illumination it fixes it too
Which shows u how coupled it all is
olive sable
satsifactory gets me 1440p 200fps rn on high settings on my 7900xtx.
but they do...
i think they also made all the buildings data only, instead of in normal UE5 where each object has a update loop and stuff
silent cloak
They did good with the mess epic gave them
silent cloak
Its still an enjoyable game but rendering is definitely the weakest part
(That and rail building)
olive sable
lmao
silent cloak
I love building a line and then having "sorry there tiger i cant bend the rail a single degree more!"
olive sable
im a bit spoiled with my hardware so i dont have any issues with rendering it. im jsut impressed by the amount of hardware util they get out of my pc
silent cloak
Then i have to destroy the whole line
There is a mod that adds in servers which i might use in the future to avoid it

silent cloak
<:neuroHypers:1135051812722982922>
Has anyone ever used the hex option
olive sable
why exactly were these ranges picked
companies randomly picked internal IP addresses. This caused massive connection errors when they tried to link to the public internet. The new standard divided private spaces into three distinct sizes to fit different organization needs:
Class A (Large): 10.0.0.0 to 10.255.255.255 (16.7 million addresses for massive corporations).
Class B (Medium): 172.16.0.0 to 172.31.255.255 (Over 1 million addresses, split into 16 blocks of 65,536).
Class C (Small): 192.168.0.0 to 192.168.255.255 (65,536 addresses, perfect for home routers).

why 172.16.x.x to 172.31.x.x and 192.168.x.x though lol? those seem so specific

No the hex view on the request
that would be useful for manipulating magic bytes .e.g for upload file type bypass based on magic bytes
silent cloak
Thougt it just converted the entire request into hex like some translator website
olive sable
why 172.16.x.x to 172.31.x.x and 192.168.x.x though lol? those seem so specific
just cuz it fitted nicely at the time i think

just unused adress space

But also, I think the issue is not bad sector
Well, it could be that or the communication line is fucked
Because it is possible the device is in the same I2C bus
Reading the PLL register and returning 0xffff smells like I2C too
Because the controller would hold the line high via pull up. Lemme check again the common thing to do on SPI
Yeah, so it doesn't usually use a pull up because most SPI uses push-pull
Unless the designer of the board do it anyway

Yeah, not really possible to do well.
There's the gcc expression statements extension.
You can abuse the co_await operator but then it needs to heap allocate the coroutine frame and for some reason I could only get that to work on Clang and MSVC without segfaulting.
Otherwise you're left with things like OUTCOME_TRY(auto var, func());

Well, depending on what set you were in
olive sable
what the hell is a set?
i know what it means in math
but i doubt you mean a well-defined collection of distinct objects
stray dragon
what the hell is a set?
they're probably talking about taking math classes from the next grade or two up
sick owl
what the hell is a set?
In the UK classes for maths are divided into sets based on ability with different curriculums and exams
People are assessed at the end of every year and sometimes term to determine whether they should go up, stay in the same set or go down
Bottom set is simplified and often populated by students who need extra support, middle is the standard curriculum and top is ahead of the curve
Ngl I thought the US did this too
stray dragon
we do but it's mostly just kids getting a grade or two ahead or behind in math classes
sick owl
Ngl I thought the US did this too

getting behind is rare, as is getting 2 grades ahead
sick owl
Students can also move at the schools discretion independent of grades here
If a case is made that they're in too low of a set they can be moved up any time
Moving down is generally restricted to assessments though
stray dragon
not sure how that works here but probably about the same
i got moved up early into 8th grade after saying i'd already read the material in a textbook (i had moved from a different school partway through 7th grade)
they did have me do a test to determine which math class i should be in when i transferred
seems lenient
olive sable
is an algo to find all primes in [0,x] technically the same as an algo to find the non-primes in [0,x]?
cuz you can technically jsut invert it and get the same output
opaque sigil

Ngl I thought the US did this too
you can accelerate in the us curriculum but it's a but spotty and dependent on the school's willingness
citation: i literally did the same course three years in a row because of that
opaque wharf

Yeah, this is what 3 hours of sleep does to a person
Also made a mistake. It should be
2tan(\theta)cos^2(\theta)
And that comes out to sin(2theta)
