Half-Life: Alyx update adds desktop foveated rendering

Valve released an update for Half-Life: Alyx that brings foveated rendering to desktop for supported hardware. The setting is under Advanced Performance; AMD users must launch with -vulkan. The patch also improves reprojection on Steam Frame and fixes workshop rendering crashes.

• Desktop foveated rendering supports NVIDIA GTX 16XX+/RTX 20XX+ and AMD with -vulkan
• Eye tracking on the headset is required for best results
• Stencil buffer tagging added for native Steam Frame runs to improve reprojection
• Fixed rendering crashes in workshop content and the Gnome Alone achievement
