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…

BMW is a nightmare to benchmark because of the way it arbitrarily changes the render upscale percentage whenever you change settings. Dunno if there is a settings bug or what going on, but I highlighted it as an outlier to potentially ignore.

I found this link Allocating GPU memory seems to be a system-wide blocking operation · Issue #164 · NVIDIA/egl-wayland · GitHub im not sure if it’s specifically related to the DX12 performance loss or not, but the OP of the post is using a really good tool to diagnose/debug the issue. I thought I m…

[image] sevenseraphim: Allocating GPU memory seems to be a system-wide blocking operation · Issue #164 · NVIDIA/egl-wayland · GitHub Nice catch, I remember this issue, didn’t link that time. If this it’s real problem: Every time the NVIDIA driver asks the GPU for memory, it makes a blocking …

The Finals still has like a 25% performance drop when using DX12, in case anyone cares. Frame generation still broken too.

Can confirm. When testing The Finals with AMD 9070 XT, I never even saw my FPS counter dip below my 230 FPS cap, and typically sub 1ms frametime variance. With 5070 ti it’s all over the place 140-185 FPS with poor frametime consistency. These have almost identical rasterization performance and sho…

Who knows? Maybe Nvidia could pleasantly surprise us for once and fix both these issues together? 😁✌🏻 Right Nvidia? Right, right?? Please say yes. You do still care about us I hope… You know, you’re wonderful, lovely, customers and stuff. 😇 (Edit: oh and also the VRAM issue too. Thanks! 🫶🏻)

Correct me if I’m wrong, but if this issue with DirectX 12 and VK3D performance is related to allocating GPU memory, it seems to be a system-wide blocking operation. Is this the same issue on the Windows NVIDIA driver side? Because from what I’ve read from the thread before, it doesn’t lead me to o…

Windows doesn’t seem to have these same issues, the Nvidia drivers are better optimized for it. Games that utilize DirectX 12 take a 15-20% performance hit on linux (sometimes more) with Nvidia graphics cards due to a driver issue. (AMD doesn’t have this problem with DX12 games on linux) There see…

DirectX12 performance is terrible on Linux

Please also look at Non-existent shared VRAM on NVIDIA Linux drivers. Maybe both memory issues can be fixed together.
