Konstantin Seurer, a Mesa developer, has spent the past couple of months working on CPU-based Vulkan ray tracing—naturally, some folks will express scepticism about this project's practicality. Seurer has already set expectations with a brief message: "don't ask about performance." His GitLab merge request page attracted Michael Larabel's attention—the Phoronix founder and principal author was suitably impressed with Seurer's coding wizardry. He: "managed to implement support for VK_KHR_acceleration_structure, VK_KHR_deferred_host_operations, and VK_KHR_ray_query for Lavapipe. This Lavapipe Vulkan ray tracing support is based in part on porting code from the emulated ray tracing worked on for RADV with older Radeon GPUs." A lone screenshot provided evidence of Quake II running at 1 FPS with Vulkan ray tracing enabled—this "atrocious" performance was achieved thanks to a Mesa Lavapipe driver "implementing the Vulkan API for CPU-based execution."

VideoCardz has highlighted an older example of CPU-based rendering techniques: "this is not the first time we heard about ray tracing on the CPU in Quake. In 2008, Intel demonstrated Enemy Territory: Quake Wars running at 720p resolution at 14 to 29 FPS on 16 core and 20-35 FPS at 24 core CPUs (quad-socket). The basic implementation of ray tracing in 2008 is not comparable to complex ray tracing techniques designed for GPUs, thus the performance on modern system is actually much lower. Beyond that, that game was specifically designed for the Intel architecture and used a specific API to achieve that. Sadly, the original ET demo is no longer available, it would be interesting to see how it performs today." CPU-based Vulkan ray tracing is expected to hit public distribution channels with the rollout of Mesa 24.1. Several members of the Phoronix community reckon that modern AMD Threadripper PRO processors have the potential to post double-digit in-game frame rates.

Gematsu - a Japanese news site - has discovered that the Game Rating and Administration Committee of Korea uploaded its rating of an announced remake of Quake II (1997) on May 31—apparently "not suitable" for youths. This could repeat a pattern from 2021, where the same committee registered the original Quake's remastered version prior to an official unveiling at that year's livestreamed QuakeCon event.

QuakeCon 2023 is heading back to its roots—with a return to an in-person format "at the Gaylord Texan Resort & Convention Center in Grapevine, Texas from Thursday, August 10 through Sunday, August 13." It is quite possible that Quake II Remastered will get an unveiling at the late summer convention. It will be interesting to see how the upcoming remaster will sit beside the existing RTX version—the South Korean rating info mentions new online multiplayer options, 4K resolution plus widescreen support, as well as support for community modification.
