Broken Particle Effects for CS2 on linux

[Fluzz]

Particle effects on cs2 is extremely broken on linux and it seems like it is not a distro specific issue. I haven't captured it but molotov effects are even worse. None of the graphic settings help. Tried a bunch of different proton versions and even distros but issue persists. It mostly effects smoke and fire effects. I noticed shadows on vegetation glitching too.

Hi Fluzz,

Thank you for contacting the Intel Community Forum.

To assist us in investigating the issue further, could you please help provide the following:

1. Could you confirm the exact make and model of the GPU you are using?
2. Which graphics driver version is currently installed on your system?
3. Does the issue occur consistently across all matches or maps, or is it limited to specific ones?
4. Are the visual issues limited to smoke and molotov effects, or do other particle effects appear affected as well?
5. Do the graphical glitches appear immediately upon launching the game, or do they develop after some time during gameplay?
6. If available, have you tested whether the same system behaves correctly when running on Windows?

Additionally, could you please generate and share the SSU (System Support Utility) log file for further analysis? When generating the report, please ensure that the Network tab is unchecked.

Best Regards,

I am on arc b580, Mesa 26.0.4. It occurs on all matches and as you can graphics settings display page. There is no other particle i know of that has an issue. Also stuff like smoke grenades are fine it is just the fire and the smoke rising from the fire that is affected. They appear right from the start. And i don't think they have this problem on windows. Here is an ssu i generated not so long ago. Also i haven't been able to capture it and it is probably another issue but the shadows on the leaves are bit glitchy too. It is not possible to capture it with a screenshot though as they look perfectly fine there. If you ask for it i might set up obs and capture it.

Hi Fluzz,

Thank you for your patience. I am still actively investigating this issue. To help move forward Could you please provide additional information?

1. Are you currently using Arch Linux on your system?
2. Have you had a chance to try Ubuntu? since it’s the officially supported Linux distribution for Intel Arc GPUs.
3. Have you attempted installing the drivers using the instructions from the Intel documentation on installing client GPUs?

I am currently on nixos, i was on arch and if i remember correctly the issue was on arch too. I haven't tried ubuntu. Are you asking me these because you haven't been able to recreate this on ubuntu? If cs2 works perfectly in ubuntu i might close this thread and look for other problems.

Guys, are you serious?
CS2 still doesn't work properly on Windows 11.
Here's a thread about it...

I've got a new ssu and the problematic particle effects as you asked. Video quality may not be great, i just tried to get within upload limits. But as you can see fire effects are extremely broken as well as dust particles from knife attacks while smoke is perfectly fine.

Hi Fluzz,

Thanks again for your patience. To ensure we're on the right track, I’d like to ask a few more questions that could help us move forward:

1. You mentioned you’ve been using NixOS and previously Arch Linux have you had a chance to test Ubuntu? Since those are the official supported Linux of Arc GPUs, I’m curious if using one of them might make a difference in your case.
2. If you have tried Ubuntu, did you follow the installation steps outlined in the Intel documentation for installing drivers?

Your answers will help us find the cause of the issue and the best way to fix it. Looking forward to your reply!

Unfortunately i haven't been able to test on ubuntu. Have you not been able to recreate the issue on ubuntu?. In the mean time i tested directx12 too thinking it may be ok but it is exactly the same as vulkan version.

Hi Fluzz,

Thank you for letting me know that this has not yet been tested on Ubuntu. I will investigate further and provide an update as soon as a resolution is available. I appreciate your patience and understanding.

Hi Fluzz,

Thank you for your patience while we investigated the issue.

We attempted to replicate the issue you reported on Ubuntu but were unable to reproduce it on our end. Could you please try installing Ubuntu and confirm whether the broken particle effects issue in CS2 persists on your system? This will help us investigate the matter further.

For your reference, we have attached images of our test results.

If you have any questions, please let us know. Thank you.
