DirectX 12 games ran through Proton/Wine on Linux perform so much worse compared to Windows. This can’t be just the overhead from the translation as AMD GPUs perform just fine, but I think it’s due to a lack of proper driver optimizations. DXVK and VKD3D developers have acknowledged this and they c…

Around 15-25% performance loss in the Dune Benchmark compared to Windows.

Does that happen on Linux and Windows using Proton?

From what I’ve observed when I tested, using vkd3d-proton in Windows gives the same performance drops as seen in Linux. So the issue isn’t limited to the Linux driver, it’s a general “Nvidia vkd3d-proton” issue. I’m honestly so close to just give up and buy an AMD RX 9070 XT, since the issues with…

Robocop: Rogue City. Linux 50 FPS Avg. [Screenshot_20250310_153933] Windows 75 FPS Avg. New games seems to be coming out exclusively under DirectX12 API, so this should be address soon.

Above Linux, below Windows: [imagen] There’s approximately a 20% performance loss on Linux compared to Windows. NVIDIA, please fix your drivers or consider open-sourcing them (at least the relevant parts) so the community can help address these issues.

FYI, this is now tracked. [image] 570 release feedback & discussion Linux Hi @RyzenDew , are you referring to DirectX12 performance is terrible on Linux ? @amrits has filed a bug to track this issue. It is under review. Bug #5131298. Thanks

So years after, NVIDIA finally acknowledged this issue! Hope we will see fixes coming this year.

My data, FWIW. AMD7600X GPU Nvidia 4070 Ti Super GPU 64 GB RAM Starfield using DLSS Balanced, 4k, frame generation on Windows 11 24H2, 572 drivers, Starfield in Akila City averages 100 FPS Linux Mint 22.1, 570 drivers, Starfield in Akila City averages 63 FPS This is using the same mod loadout…
