XESS support for VR games

[hwahart]

Hi Intel,

I've heard it would be hard to implement a XESS solution for VR games, having 2 different screens to be mapped again would overall make the GPU work harder? Is this so ? Does the faster engine of XESS be able to overcome such problems ?

Hello hwahart,

Thank you for posting in the Intel® Communities Support

For us to better understand the situation, are you referring to our Intel® Arc™ discrete GPUs? Or to our processor/integrated graphics?

Best regards,

Jay B.

Actually,

Both choices. Would it be possible to have the GPU do 1 of the VR sides and the CPU intergrated iGPU do the other side of the 2 to render eyes having targeted for each eye to display a VR screen with its own dedicated "rendering" ?

Hello hwahart,

Please be advised that Intel Arc graphic's support for VR headsets continues to evolve as we ramp our products and add updates to our software stack.

Also for Intel integrated graphics, the iGPU may not provide the necessary performance needed for a good VR experience. Unfortunately, is not designed for VR either, since VR requires dedicated graphics for smooth and better experience.

Best regards,

Hi JayB,

I was thinking on the XESS, supersampling, Anti aliashing matters, not on the ray tracing, my INTEL ARC A770 still is not compatible with Oculus / Meta app, and still has not enough power or driver adaptability to match all the games. See the image,  "Blade & Sorcery" handling in "direct sunlight" in game ok, but when in shade or not direct sunlight, it shows the "build lines" of the 3d objects & humans. 

The newer "meteor lake" iGPU would be advertised between 4.6 and 7 Tflops, no match against the GPU Arc A770,

could it be able to cooperate "deeplink" and handle half of the "threads" for 1 of the screens in the VR only  to handle the anti aliashing supersampling, the faster method of the advertised faster (see rendering pipeline) sampling. Its only an idea for "intel deeplink" to exploit marketshare in VR.

Hello hwahart,

We appreciate your feedback, I'll forward it to the team in charge for consideration however we cannot promise any particular outcome since VR support is still a work in progress for Arc GPUs. The Intel XeSS technology continues to evolve so I invite you to watch the latest updates and implementations here: https://github.com/intel/xess

In light of this, we will be concluding this inquiry. Should you require additional support in the future, please feel free to initiate a new query, as we will not be monitoring this thread moving forward.

We are grateful for your input and thank you for reaching out to us.

Best regards,
