XeSS on Intel Arc (via OptiScaler): XMX or DP4a?

[Rownak-Hasan]

I’m using an Intel Arc B580 GPU. When I enable XeSS upscaling through OptiScaler, does it use the XMX path (native hardware acceleration on Arc GPUs) or does it fall back to the DP4a path?

I want to confirm specifically how OptiScaler handles XeSS on Intel Arc cards.

Hi,

OptiScaler specially disables spoofing for XeSS libraries so XeSS on OptiScaler uses XMX path.
