Compatibility Report

  • Name of the game with compatibility issues: Aces of Thunder
  • Steam AppID of the game: 2754090

System Information

  • GPU: RX 7900 XTX
  • Video driver version: 25.3.4
  • Kernel version: 6.18.8-273-tkg-eevdf
  • Link to full system information report as Gist: https://gist.github.com/Patola/5e31a3e3fbf396113033b70f1e64df85
  • Proton version: 10.0-4, also tested 9.0-5 and experimental (removing the prefix between each attempt). Not that is matters to this issue but I have also tested with GE-Proton10-28 and GE-Proton10-29, unofficial versions, and purged everything after this attempt to try again with the regular proton. I am sending only the proton 10.0-4 log because the symptom is the same on all of them.

I confirm:

  • [X] that I haven't found an existing compatibility report for this game.
  • [X] that I have checked whether there are updates for my system available.

Note

This is a VR optional game. However, it is not starting correctly even in flatscreen mode. As a way to simplify treatment, I am first just saying the issues in flatscreen mode, and I will augment with VR data later.

Symptoms

Game shows the start screen, asks to press space to continue, says we're authorized, and throws the player in an empty field with some fire in the distance. In this empty field, some controls work (WASD + mouse-button to change the view), but there are no menus, no objects, no other controls working.

Reproduction

Just start the game.

VR

So, the symptoms in VR are the following:

  • For information: I am using the official Steam Link client on the Meta Quest 3 headset, SteamVR version 2.14.5.
  • In Proton 10.0-4, instead of the initial screen before the plain terrain, the game window is completely black.
  • In Proton Experimental, the initial screen works and you get thrown inside the same empty terrain but in VR. And as in the flatscreen mode, you can only move (teleport) around and not do anything else.

I understand that in proton experimental the OpenXR initialization code works correctly (recent fix that will be eventually applied to proton stable), but the other issues remain. I am first sending a simple PROTON_LOG=1 %command% logfile and a video showing how it went.

Video is on youtube: https://youtu.be/zACPYqvIgtQ

Now I did the same as above but instead I've used as launch parameters: PROTON_LOG=+vrclient,+openxr,+file %command%

The result is this 86 MB logfile (uncompressed) I am attaching but zipped (2.2MB).

Still with PROTON_LOG=+vrclient,+openxr,+file %command% I did the same as above but with Proton 10.0-4. The VR screen never initializes, SteamVR doesn't fade to black, and in a very short time it generates a 431 MB logfile, attached here.

So, I am trying to be thorough on my bug report because I am refunding right after this, being unable to provide more data before the game is sold at a considerable discount. No offense, but this game is expensive and I've opened many other bug reports (like the one for Glassbreakers) that have no activity at all for more than one month, so I don't know if in one hour I will receive a follow-up or if this issue will stay silent and take years to resolve.

Any news on that game? Even the flat version? It's on sale again.

I have had luck getting it to render in using proton-cachyos-11.0-20260506-slr-x86_64_v3 with the following launch command

PROTON_VKD3D_HEAP=1 VKD3D_CONFIG=enable_experimental_features,descriptor_heap,no_upload_hvv,single_queue %command%

What also solved the issues I was having with Forza Horizon 6

@Agent6472 you mean you are able to play the game? Are you playing it in VR or flatscreen?

AAgent6472 2026-05-23 github

@Patola can confirm flatscreen. Just moved from Pop_OS to Bazzite so I haven't had a chance to re-set up the vr but its looking good so far.

@Agent6472 what GPU and drivers do you have?

AAgent6472 2026-05-24 github

@Patola Nvidia 3060ti on 595.71.05

Seems like enable_experimental_features was the key. The non-VR version at least should work with the linked PR.

Now that the non-VR version is working, what do we need for the VR version to work?
Do you need more tests? More logs?

I have repurchased the game now and I want to play it in VR.
