Für die kostenlose Raytracing-Version des klassischen Shooters Quake 2 steht nun der Patch 1.5 auf Steam für Linux bereit:

Quake II RTX 1.5 PATCH

Hey, everyone! Today we're releasing v1.5, featuring the below features, fixed issues, and improvements.

New Features:

Added support for ray tracing using the `VK_KHR_ray_query` extension API.
NOTE: This is an optional feature, and the two previously supported methods, `VK_NV_ray_tracing` and `VK_KHR_ray_tracing_pipeline`, are still supported. We recommend using NVIDIA Graphics Driver version 465 or newer, or AMD Radeon Software version 21.3.1 or newer.

Fixed issues:

Fixed the crash that happened on some systems when the game is minimized: https://github.com/NVIDIA/Q2RTX/issues/103
Fixed the invalid Vulkan API usage that happened in the bloom pass: https://github.com/NVIDIA/Q2RTX/issues/104
Fixed the invalid barrier for an inter-queue resource transition: https://github.com/NVIDIA/Q2RTX/issues/105
Fixed the out-of-bounds addressing of the framebuffer array: https://github.com/NVIDIA/Q2RTX/issues/107

Misc Improvements:

Reduced the delay after resolution changes by avoiding re-initialization of the RT pipelines.
Changed the memory type required for the UBO and transparency upload buffers to `(HOST_VISIBLE | HOST_COHERENT)`.
Improved logging around SLI initialization.
