\nIn addition to Mesa’s open-source Radeon Vulkan driver “RADV” making some nice performance improvements<\/a> for modern AMD GPUs with hardware ray-tracing, the emulated ray-tracing code path in RADV for primarily older GPUs has seen some improvements merged this weekend. In fact, so significant that from one merge request is around 40% faster performance for the Quake II RTX game with the emulated RT handling.<\/p>\n

Konstantin Seurer has implemented proper water tightness handling for the emulated ray-tracing code path in RADV. For ray-tracing, water tightness refers to accurately handling intersections with surfaces such as at edges and corners. <\/p>\n

With this merge request for watertight ray-triangle intersection in the emulated code path in RADV, it’s now using FP32 rather than FP64 and contains other improvements over the older code. <\/p>\n

“Instead of using fp64 (Which is broken in some cases) the new approach only uses fp32 and implements tiebreaking for edge\/vertex hits. Using fp32 is also much faster, improving performance of q2rtx by around 40%.”
\n
Yes, this merge request<\/a> merged today for the newly-started Mesa 25.3 development cycle scores around 40% better performance for Quake II RTX when using the emulated ray-tracing support.<\/p>\n

Konstantin Seurer who authored that merge request also landed another merge<\/a> to enhance the RADV ray-tracing support by implementing null acceleration structure support in the shader code. Konstantin Seurer is one of the developers working on the Mesa RADV code thanks to Valve.<\/p>\n","protected":false},"excerpt":{"rendered":"In addition to Mesa’s open-source Radeon Vulkan driver “RADV” making some nice performance improvements for modern AMD GPUs…\n","protected":false},"author":2,"featured_media":10407,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[5870,59,5869,5867,5866,5873,5871,5868,5872,5865,5876,86,5874,5875,56,54,55],"class_list":{"0":"post-10406","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-technology","8":"tag-desktop-linux","9":"tag-gb","10":"tag-linux-benchmarking","11":"tag-linux-hardware-benchmarks","12":"tag-linux-hardware-reviews","13":"tag-linux-how-to","14":"tag-linux-performance","15":"tag-linux-server-benchmarks","16":"tag-open-source-graphics","17":"tag-phoronix","18":"tag-phoronix-test-suite","19":"tag-technology","20":"tag-ubuntu-benchmarks","21":"tag-ubuntu-hardware","22":"tag-uk","23":"tag-united-kingdom","24":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/10406","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=10406"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/10406\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/10407"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=10406"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=10406"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=10406"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
