Linux support for XMX accelerated XeSS

[Hion-V]

I bought a B580 to replace my aging GTX 1070 TI with the expectation of good support for gaming on Linux. Now I come to find out that not only is using XeSS through proton not hardware accelerated using the XMX cores, making it perform far worse, but that there are no plans to support this?

Why? Are you mad?

The amount of games that come out now that require hardware accelerated upscaling to get responsive gameplay performance, this essentially renders the graphics card unusable for gaming on Linux. 

I and many others have no desire to run Windows, meaning we're SOL and should have bought an AMD graphics card instead.

I urge you to consider supporting XeSS on Linux, or open up the API for XMX to allow development on solutions like optiscaler to fill this hole.

Easy to say, given the current state of affairs, I have buyers remorse.

Hello Hion-V,

Thank you for posting in Intel community Forum.

Before we proceed, I need to clarify. Are you just providing suggestion or recommendation for Arc Graphics to support XMX accelerated XeSS or are you reporting an issue?

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

Best regards,

Consider this both a feature request, and me reporting a problem, because no support for this on Linux, is in fact a problem. With how terrible Windows is, and how many people are looking to move away from it, not having the feature supported on Linux means the implementation cannot be considered complete.

So, to clarify once more. I'm asking for either:

• Official native Linux hardware acceleration support for XeSS

or:

• Make required components of the XMX API available for Linux developers so that third parties can do the work to support this.

Currently, without support, XeSS on Linux runs in cross-vendor fallback mode, leading to XeSS performing poorly.
