@KhanhDTP, I used Mangohud and it showed the GPU did go up to 1GHz in most of the time (though not all the time) and the GPU usage is ~100%. Maybe I need to test more games I did see a ~7% boost for vkmark score to ~4400

@KhanhDTP, I've tried the 1GHz GPU patch but so far I do not see much performance boost with it. I tested Silk Song, Hitman: Absolution, Mario Kart 8

@KhanhDTP, thanks for the info. Great news! I'll try it. Have you tried the new dxvk 3.0 release?

In addition, there's a develop branch for the VK_EXT_transform_feedback extension. It is another important requirement for DXVK.

@KhanhDTP There's no pull request yet but they do have a preparation PR https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/41654 For DQ 11S, it's about 15 fps@1080p. The FPS varies depending on the gaming scenes. You can check out my video https://b23.tv/xvsMPqD

@KhanhDTP now panvk has a in-develop geometry shader feature branch. I've tried it and some dx11 games like Dragon Quest 11S and Octopath Traveler can run.

Please note that it is a known issue that Turnip / Vulkan broken on Snapdragon SM8550 / Adreno 740 on Mesa 25.3.x. See https://gitlab.freedesktop.org/mesa/mesa/-/work_items/14656 The workaround is to apply patch from https://github.com/batocera-linux/batocera.linux/blob/master/board/batocera/patches/mesa3d/001-fix-freedreno-vulkan.patch and rebuild 001-fix-freedreno-vulkan.patch

Now this issue seems to be fixed. I tried to build 6.18.25 kernel and it can complete boot wizard as expected.

@KhanhDTP are you using esync of wine? NTsync is available on 6.18+ rk3588 kernels. I think that may give a performance improvement.

@KhanhDTP, that's great news! Thank you very much for the testing!

@KhanhDTP gpu clock is still limited to 850mhz with 7.0. I tried to port rockchip vendor kernel clock settings but no success yet. @chaitan3 The gpu can clock up to 1Ghz by hardware design but it is limited to 850mhz with mainline kernel.

@KhanhDTP BTW, I'm using the edge 7.0-rc3 kernel. Did you find the vendor 6.1 kernel is more stable?

@KhanhDTP Now Call of Duty 2 can be launched with dxvk 2.7.1 + mesaaco ppa.
