Automated
[√] Manual

If on AMD/Intel and Automated, used DLSS inputs?

Yes
[√] No

Also please mention in description which upscaler inputs are used (which upscaler you selected in game settings).

Did you check the Wiki and Compatibility List?

[√] Yes
No

Please describe the issue and steps to reproduce it

Using pre10 or slightly earlier versions works fine, but in newer versions there is an issue when calling CreateDXGIFactory.

Intercepting IntelControlLib.dll resolves the issue.

Can you check latest master after 500369e23d?
Dxvk 2.7 seems to be running fine on AMD now but dxvk-git is a mess and I don't know if we are to blame or some dxvk vs amd driver incompatibility that only shows up when Opti gets involved.

The latest version does not resolve the issue. At present, it still appears to be a problem with GpuInformation IdentifyGpu::getPrimaryGpuVulkan().

There are some issues with DXVK on Windows for sure. Master should be better now, even on Linux but dxvk-git on AMD on Windows is still a mystery to me

DXVK 在 Windows 上的确存在一些问题。Master 分支现在应该好多了，即使在 Linux 上也是如此，但 Windows 上 AMD 平台的 dxvk-git 对我来说仍然是个谜。

Does disabling getPrimaryGpuVulkan have a significant impact on the overall system?
Only a small change is needed to fix the issue, but it requires disabling getPrimaryGpuVulkan.

I may be able to get rid of getPrimaryGpuVulkan entirely now. Just need to be careful to not end up in a loop with DXVK. Imagine a vkCreateInstance call from the game -> we call DXGI to query GPU -> DXVK calls vkCreateInstance -> back to start.

How is the situation with the latest master? I've added some fallbacks and removed vulkan query entirely.

When enabling NVIDIA spoofing in dxvk.conf on non-NVIDIA GPUs, Vulkan_Spoofing.cpp incorrectly adds the NVNGX Vulkan extension. It is hoped that more validation checks can be implemented.
