http://bugs.winehq.org/show_bug.cgi?id=56167 --- Comment #3 from Béla Gyebrószki <gyebro69@gmail.com> --- I revisited this bug and ran the benchmarks again in vanilla Wine-11.0-rc3. I also tried the proposed patch on top of 11.0-rc3: https://gitlab.winehq.org/wine/wine/-/merge_requests/9811 The Nvidia drivers I tested this time: 590.48.01 (open), 580.105.08 (proprietary), 570.207 (proprietary). The hardware and the settings used in Unigine Heaven were the same as in my original post. GPU: NVIDIA GeForce GTX 1660 SUPER - 6 GB VRAM (Turing family) CPU: AMD Ryzen 5 5600X (12) @ 3.70 GHz (Cpu boost disabled) Preset: custom API: DirectX 11 Quality: Low Tesselation: Disabled Stereo 3D: disabled Multi-Monitor: disabled Anti-aliasing: Off Full Screen: unchecked Resolution: 1280X720 I'm mainly still using the "old" WOW64 mode and it is shocking that there is a massive 40-45% performance loss with EGL compared to GLX in 11.0-rc3. This affects all 3 benchmarks in Unigine Heaven: DX11, OpenGL and DX9. With the new WOW64 there is only 5-6 % performance loss with EGL in the DX11 benchmark, a mere 2-3 % loss in the OpenGl benchmark and 10-11% loss in DX9 (compared to GLX). About the patch (MR9811): In the old WOW64 mode it barely gains 4-5% with EGL, but gives more than 60% boost in the DX11 benchmark with GLX. In the new WOW64 the patch gives about 50% more fps both with EGL and GLX. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
