Hello!
I did not have that problem with the game, but my wheelbase and pedals are different.
OpenFFBoard + FreeJoy pedals + GT Neo all connected and detected by the game, without issues. Force Feedback also working.

But i have another issue: graphical artifacts present, look like polygons glitching on car interior, dashes and mirrors
Also tried various graphical settings and RADV_DEBUG=nodcc, without luck.
These artifacts does not appear on any other game, so GPU is not a problem.

Video with artifacts: https://www.youtube.com/watch?v=Yb-y3J-lbbo

Another user with Nvidia GPU reports that game is working without any artifacts.

Looks like Mesa/DKVK issue?

GPU: AMD Radeon RX 6900 XT
Video driver version: Mesa 24.2.8-1, AMDVLK 2024.Q4.3
Kernel version: 6.12.6-1
Link to full system information report as Gist: https://gist.github.com/JacKeTUs/56c34143883c3e2661f30d1e800e5058
Proton version: Proton Experimental, but also tested Hotfix, 8.0-5, 9.0-4, GE-Proton9-22

UPD: I tested with AMDVLK, 2024.Q4.3, artifacts are present as well. Performance is worse, 30fps vs ~120 fps on Mesa
UPD: no changes with new update (0.1.1)
UPD: no changes with new update (0.1.2)

I hear the game is working fine on Steam Deck without artifacts, and I believe for other RADV users.

I won't be able to play until I get home, so I will have to test later, but I am using the latest Mesa version (Kisak PPA).

I have tested on ChimeraOS same artifacts here. I have a problem with OpenFFBoard the buttons not work very well.
Performance are not the best but i have the minimum hardware required.

In that case, I guess someone could file a bug report to Mesa about this?

Hello

Once I launch the game with my Fanatec CSL DD ... the game spawns the window, then crashes.

This is a known bug which affects a couple of games that come with the FanatecSDK. In short, it seems that the wheel detection of FanatecSDK throws an exception when it finds a compatible wheel but it cannot really talk to it.

This is why I'm working on supporting a hidraw mode for Fanatec wheels, which allows the FanatecSDK to talk to the wheel 'the same way' like in windows, see gotzl/hid-fanatecff#86 and this comment gotzl/hid-fanatecff#86 (comment). With this branch of the driver, and the posted proton version, I'm able to run ACE and I get FFB/LEDs ...

[mferraci]

I confirm same visual artefacts than @JacKeTUs
6950XT with Mesa 24.3.3

And I also confirm that hidraw branch of fanatec driver made by @gotzl makes FFB and LEDs works perfectly

[kropop]

I can also confirm the new fanatec driver makes my wheel work perfectly, with one caveat: it is detected as "Thrustmaster Sim Pedals", so I have two devices using the same name, but one of them are the actual pedals, the other one is my Fanatec wheel. This peculiar issue is also visible in ACC with this Proton version.

I still get a lot of stutter, making the game unplayable completely. I don't see any visual glitches, though.

Once I launch the game with my Fanatec CSL DD ... the game spawns the window, then crashes.

What I think. ACE detects Fanatec gear and auto enables Fanatec SDK (on ACC it's Fanatec LED's (schreenshot bellow). That's why only gotzl/hid-fanatecff#86 works.

Tested with different proton versions, all of them crashes (if Fanatec gear is connected). Without Fanatec, it starts with no issues.
And the biggest issue here, there is no ability to turn OFF Fanatec SDK (Fanatec LEDs).

And I can confirm a lot of stutters. This happens always in the same place on track. For example on Brans Hatch first corner, then third one. On back straight near arch. When stutters happens GPU load drops to zero, and then jumps back to full load.

Just clicked play and the game works but there are graphics issues like these:

Tried running Proton Hotfix and ProtonGE-22, lowest settings and even a different pp filter but the issue still shows up.

After messing with graphics settings it's fine for a couple of seconds and then goes back to having issues again.

Forgot to include this

[galacticaledge]

Is any contributer here able to tell us if the graphical bugs on AMD are a RADV problem or possibly a problem with Proton/vkd3d-proton?

You're using an older Nvidia driver, so upgrade to the latest one (in this case, 565) if possible.
