Intel向Proton提交代码使XeSS调用XMX快速升频
Intel submits code to Proton to improve XeSS to use the fast upscaler XMX
Intel向Proton提交代码，使XeSS能调用XMX快速升频而避开慢速回退路径。开发者Damian Tomczak在Valve的Wine GitHub提交四个PR，协同修改wine、vkd3d-proton、dxvk和Proton以启用XeSS XMX加速。原文作者认为此举将改善Steam Deck等Linux设备的游戏升频表现，因XeSS有时优于AMD FSR。
Looks like Proton with Intel XeSS is set for some improvements, with Intel submitting code directly to Valve. This is in addition to the recent news of DXVK-IGDEXT.
Developer Damian Tomczak opened an issue on Valve's Wine GitHub page noting:
"Adds a builtin libxess.dll which forwards the XeSS D3D12 calls to the Linux XeSS library (libxess.so), so XeSS can use XMX (the fast upscaler) under Proton instead of the slower fallback path. D3D12 objects are converted to Vulkan through vkd3d-proton's interop interface.
The DLL is only used when Proton finds a libxess.so, first in its contrib directory and then in the system library path. The path is passed in XESS_LIB_OVERRIDE. Otherwise the game's own libxess.dll is used.
Part of the [XeSS XMX] series, see the comment below for the other PRs."
And in the follow-up:
"This is one of four [XeSS XMX] PRs that together add XMX-accelerated XeSS to Proton:
- wine: xess xmx: Add builtin libxess.dll to enable XeSS XMX path under Proton.
- vkd3d-proton: xess xmx: Enable the Vulkan extensions and features XeSS requires.
- dxvk: [xess xmx] Don't hide Intel GPUs when XeSS is provided by Proton.
- Proton: xess xmx: Use a native libxess.so for XeSS when available.
The Proton PR bumps the other three submodules, so it should go in last."
Sounds good, and if it means XeSS will work better in future - that's awesome. As it can beat AMD FSR at times, especially in certain titles on the Steam Deck. Nice to see Linux gaming with Proton continue to get better, especially when it's coming direct from developers working for hardware vendors like this.
