Issue in proton repo : https://github.com/ValveSoftware/Proton/issues/7712

[mrdev023]

Start well on Proton 9.0-1

[HansKristian-Work]

• Does this reproduce with VKD3D_DISABLE_EXTENSIONS=VK_NV_low_latency2? That extension has a known crash on older drivers due to driver bug.
• Can you try with latest NVIDIA Vulkan beta?

[mrdev023]

Im testing already last version of NVIDIA 550.78

Is Vulkan in another version?

It work well with proton 9 but not in proton experimental

EDIT

I see 550.40.07 version https://www.nvidia.com/en-us/drivers/unix/

You talk about this version ?

NEED INFO

I have this bug https://github.com/ValveSoftware/Proton/issues/7712#issuecomment-2101032632 also but i dont know if is related to vkd3d/vkd3d or if is only a Nvidia bug or a proton bug. Does this bug tell you anything?I quickly ask here to find out if I created the issue in the right place

[HansKristian-Work]

I'm talking about https://developer.nvidia.com/vulkan-driver 550.40.61.

[mrdev023]

I'm talking about https://developer.nvidia.com/vulkan-driver 550.40.61.

[mrdev023]

Any news ?

[mrdev023]

Same problem on my other computer with RTX 2080ti. Same NixOS configuration. I can send you my configuration.

And without vkd3d, UE work good with some other issues

[mrdev023]

Crash still present with nvidia 555.52.04 @HansKristian-Work

[HansKristian-Work]

I haven't looked into this yet.

[mrdev023]

I haven't looked into this yet.

Do you have all informations to debug this ? Or you need more informations ?

[HansKristian-Work]

@runar-work tried looking at it, but there is no provided binary and he tried downloading something, but the editor doesn't boot at all on Wine.

[runar-work]

I'm able to launch it with DXVK, but that's not really helpful. What environment variables are you using for this?

[mrdev023]

I'm able to launch it with DXVK, but that's not really helpful. What environment variables are you using for this?

I use default lutris configuration but with following vars

[mrdev023]

Yes with DXVK is work but with vkd3d crashed

[mrdev023]

@runar-work

[mrdev023]

Also this

but it crash also with vkd3d 2.12 official not just with vkd3d-proton

[mbriar]

There is no vkd3d official version 2.12

[mrdev023]

Yes vkd3d 2.12 is also the proton version
