Company of Heroes 2 Graphics bug

[NagyAkos512]

Dear Intel Arc support team!

When i'm playing Company of Heroes 2, after 15-30 minutes, the textures stretch on random parts of the map. Several Arc users reported this months ago, and looks like its still not fixed. I would like to ask the support to investigate this issue, and try to help us Company of Heroes 2 players to fix this, because this is really annoying.

Since people already reported this issue earlier, i'm going to link that post: https://community.intel.com/t5/Intel-ARC-Graphics/Game-objects-stretch-and-cover-the-whole-screen-using-Arc-B580/m-p/1692339

I have exactly the same issue, i have the newest drivers, tried different graphics settings, nothing helped, i'm sure its a software side problem. 

I'll attach the SSU, and a picture of the problem. As the other Arc users who suffer from this graphics bug, i tried all the troubleshoot methods, for example lowering graphics settings, updating bios, updating graphics driver, lowering FPS, basically everything that might have helped, but the bug still occurs after 15-30 minutes. 

Please help us Arc users, who would like to play this old, but amazing game!

Thank you very much for your help!

Hello @NagyAkos512,

Thank you for taking the time to run such detailed tests and for sharing your observations. The information you provided about the different maps, settings, and comparisons with the RX460 is extremely helpful. We attempted to reproduce the issue internally, but were unable to encounter the same artifacts you described. Based on your latest findings, it seems the issue may occur under specific conditions, such as higher graphics settings, certain maps, and possibly how the shader cache interacts with the game engine.

To help us narrow this down further, could you please share the following:

• The exact in-game graphics settings you used when the issue appeared.

• Any configuration file modifications (such as ShaderQuality changes) you made.

• Screenshots or short video clips of the artifacts, if possible.

Additionally, as a precautionary step, could you confirm the exact driver version you tested with? Also, have you had the chance to perform a clean driver uninstall using DDU (Display Driver Uninstaller) before reinstalling the latest driver version 30.0.101.7028? This step helps rule out any leftover files or corrupted shader cache that might be contributing to the problem. Your collaboration and willingness to investigate further with the community are greatly appreciated. Please continue to share any new findings.

Best regards,

Hey VonM!

I'm very sorry for the late reply, I had a busy weekend and I didn't have time to test and investigate further.

My game settings are everything on the highest, but anti-alising is OFF, and vSync is also OFF, resolution is 2560x1440 120hz. With these settings, I often encountered the artifacts, lowering the graphics seemed to help, especially turning down the texture detail option to the lowest. As far as i know, if you turn down the graphics, the game automatically switches to DX9, which seems to solve this very weird graphical artifact.

The game has two different graphics related config file, one in the documents folder, and one in the game's folder. The game folder version is where I "messed" a little with the configfile. My ShaderQuality was set to 0, than I switched it to 2. TerrainDetail was -499, which I don't even understand but I changed it to 2. After this my game looked really bad, but I didn't encounter any artifacts.

I also tried to use the game's optimize my device option, after this the game gives you a settings preset which is compatible with your system. Sadly, this didn't help either.

As of now, the only solution for me is to crank down the graphics settings to the lowest, and even re-write the game's configfile graphics options. With these, I managed to play for 40 minutes and an hour long match without any issues. I also tried a 4vs4 on a huge map, I went AFK for 2 hours, and the game was still stable.

Monkiemurdie and myself came to the conclusion that its happening because of a corrupted 3D model. We are not sure which one, but it seems logical that a 3D model causes this. After 15-45 minutes is where the artifacts happening, so it might be a unit, a vehicle, a building that causes this issue, thats why its hard to reproducate in our opinion. However, these are just speculations, we are amateurs in this, trying to help you to solve this issue, not easy haha!

My current driver version is the latest WHQL driver which is 30.0.101.7026. AFAIK Monkiemurdie already tested the latest version, but he didn't report back any success. Myself already tried the latest version, which didn't solve this issue, so i reverted back to the latest WHQL driver for stability reasons. I did not use DDU the last time I updated the drivers, I used Intel's clean install feature. This should wipe out all the remaining shader cache, right?

As of now i'm away from my PC, I'll be able to attach the requestes files later on today. I would like to apologize for the late answer, school season started, its been a busy first weekend. Thank you for your understanding!

Thank you VonM for your efforts, I hope your weekend was great! I'll continue to investigate further and I'll attach the requested files later on today. I'm really grateful for your help!
