Intel graphics card users who prefer Linux OS will see much better performance Looking forward to. On Friday, the latest release of Mesa (v23.2) code included performance optimizations that will help boost frame rates for some very valuable games. For example, Counter-Strike: Global Offensive ran 11% faster on Linux with the latest code on the Intel Arc A770 graphics card.
Francisco Jerez, Intel Open Source Linux Graphics Driver Engineer Discussed Changes in intel/gfx12.5 code on GitLab. Jerez said the kernel mistakenly disabled some performance features that should have been enabled by default.
As a confusing code discovery, the ‘compressible partial write merge enable’, ‘coherent partial write merge enable’, and ‘inter-tile partial write merge enable’ bits all run on an idle system. It appeared to be enabled when Nevertheless, these L3 partial write merge functions were “broken during initialization of his 3D context by the i915 workaround”, causing a “significant performance bottleneck”.
This is a critical performance degrading code error that should be detected as it affects all DG2 (Arc Alchemist) graphics cards on Linux. This benefit will be felt by future users of Intel Meteor Lake integrated graphics.
Similar to the aforementioned 11% performance improvement (in classic FPS CS:GO), Jerez also noted that the DG2-512 sample improved Shadow Of the Tomb Raider by up to 5.5% and AztecRuins-VK by up to 6.5%. mentioned (Arc A770). No, performance degradation with the new code has been observed so far.
Finally, Jerez commented on new Mesa code that helps close the performance gap between Windows and Linux. Intel’s Arc cards show that the driver software is relatively immature and the underlying raw performance numbers (such as TFLOPs) remain potentially undeveloped, so Linux and Windows I’m pointing out that both probably see such a big improvement.
Mesa 23.2 code improvements are expected to hit stable Linux OS distributions around late August/September.
