[D9VK] Mudrunner consumes all 8GB of VRAM and locks system.

[barthess]

I play Mudrunner https://store.steampowered.com/app/675010/MudRunner/ on default settings.
I use radeontop to monitor VRAM consumption.
On vanilla maps the game consumes about 4-5GB and cause heavy sound stuttering during loading. When map loaded VRAM usage drops to ~1GB and game becomes playable. When I try to play some modded maps with lots of new geometry the game consumes all my 8GB of VRAM and locks system. Some times before system lock I can catch "radv/amdgpu: Not enough memory for command submission" message in console and similar messages in dmesg. After lock the only way out is reset button or sysrq+B. I replaced radv with amdvlk but it doesn't help. Bug reproducible with my system wine and with different proton versions in steam (checked Experimental, 8.0, 5.13). The only way to fix is disabling dxvk "PROTON_USE_WINED3D11=1 %command%" command line in Steam. I've found similar report here https://bbs.archlinux.org/viewtopic.php?id=298993

I'm not seeing excessive memory usage when replaying the trace so I'm not sure if this is exactly your problem, but the game creates several huge textures every single frame and then immediately destroys them. Needless to say, this is exceptionally dumb, and since DXVK needs to manually clear memory we're keeping these textures alive for several frames.

Can I workaround this setting low FPS limit (DXVK_FRAME_RATE=2) during game loading? Can I later set it back to 60 on the fly?

@barthess Far as I know changing DXVK_FRAME_RATE value won't do it on the fly.

Instead you can use Mangohud where you can set several fps limits in its config file and switch by press R.Shift + F1 (in my case).

@jrugia Thanks! It works for me. 20 FPS limit is enough to successful map load. Loading process became much slower but game became playable. Even with SpintiresMod.
