Warhammer 40k Space Marine 1 running below 30 FPS

Few weeks back Amazon prime gave away Warhammer 40k Space Marine 1.
I installed it on my shared internal SSD (I dual boot between Endeavour OS & Win 11) via Heroic on linux.

I ran the game with Proton experimental & GE-Proton 10-3, but none of them allow the game to go above 30 FPS. Even disabled V-sync inside game, still below 30 fps. Tried disabling E-sync & F-sync in heroic, I see no improvement in FPS.

The same game, when I launch it on Windows (via Heroic), runs above 165 Hz (crossed 200 at some points)

I have Framework 16 with the dGPU.

I have attached the logs, any solutions?

Solution

Deleted prefix & used GE-proton 9-27. Now it gives 70+ FPS!

Use this env var

dry-scarlet•6/2/25, 7:56 AM

Game settings in Heroic, advanced, scroll down a bit, environment variables

dry-scarlet•6/2/25, 7:57 AM

DXVK_FILTER_DEVICE_NAME is key, "7700S" is value

dry-scarlet•6/2/25, 7:57 AM

No need for = in there

Hmm, now that is a bit concerning.

Does other games work at full speed? Because all is done right rn

Ddry-scarlet DXVK_FILTER_DEVICE_NAME is key, "7700S" is value

worthy-azureOP•6/2/25, 8:04 AM

Did this with & without double quotes, same result in both cases

Ddry-scarlet Hmm, now that is a bit concerning. Does other games work at full speed? Because...

worthy-azureOP•6/2/25, 8:04 AM

let me check

Genshin Impact via Heroic - 60 fps
Sekiro via Steam - 60 fps
No man's sky - 80+ fps

dry-scarlet•6/2/25, 8:11 AM

Add this env var too to the game

dry-scarlet•6/2/25, 8:11 AM

DXVK_HUD=fullDXVK_HUD=full

dry-scarlet•6/2/25, 8:12 AM

And grab a screenshot while it runs at 30 fps

dry-scarlet•6/2/25, 8:15 AM

inb4 game compiles shaders so that makes a mess of your framerate

Ddry-scarlet And grab a screenshot while it runs at 30 fps

worthy-azureOP•6/2/25, 8:15 AM

It never goes above 25 fps

worthy-azureOP•6/2/25, 8:16 AM

Good point

Wworthy-azure Good point 🤔

dry-scarlet•6/2/25, 8:16 AM

On bottom left of dxvk hud it would if it compiles shaders or not

Ddry-scarlet On bottom left of dxvk hud it would if it compiles shaders or not

worthy-azureOP•6/2/25, 8:18 AM

I see

dry-scarlet•6/2/25, 8:18 AM

You see it compiles constantly or?

dry-scarlet•6/2/25, 8:19 AM

If yes, drop in game, leave it like that a bit

dry-scarlet•6/2/25, 8:19 AM

If still doesnt go away, then do this

dry-scarlet•6/2/25, 8:19 AM

https://github.com/doitsujin/dxvk/blob/master/dxvk.conf#L726

Wworthy-azure It never goes above 25 fps 🥲

worthy-azureOP•6/2/25, 8:19 AM

the graph is like that as in screenshot, with occasional spike in between

dry-scarlet•6/2/25, 8:20 AM

Create dxvk.conf file next to game exec

dry-scarlet•6/2/25, 8:20 AM

Put this in it

Wworthy-azure the graph is like that as in screenshot, with occasional spike in between

worthy-azureOP•6/2/25, 8:20 AM

those spike come only when I alt-tab in & out

dry-scarlet•6/2/25, 8:21 AM

d3d9.cachedDynamicBuffers = Trued3d9.cachedDynamicBuffers = True

worthy-azureOP•6/2/25, 8:23 AM

now the graph height increased with occasional messages of Compiling shadersCompiling shaders

worthy-azureOP•6/2/25, 8:23 AM

wait it is still same height

worthy-azureOP•6/2/25, 8:24 AM

worthy-azureOP•6/2/25, 8:32 AM

Should I leave it as it is? @"Leopard"

(I'll have my dinner in the meanwhile)

worthy-azureOP•6/2/25, 8:35 AM

I'll leave it as it is for now. Will be back after 1 hour.

worthy-azureOP•6/2/25, 9:54 AM

Unfortunately it is still 17 fps @"Leopard"

Hmm

PROTON_USE_WINED3D=1PROTON_USE_WINED3D=1

dry-scarlet•6/2/25, 10:03 AM

If this fixes perf, then you should open an issue in dxvk tracker

Ddry-scarlet `PROTON_USE_WINED3D=1`

worthy-azureOP•6/2/25, 10:03 AM

same result, still 17 fps, DXVK Hud also disappears

dry-scarlet•6/2/25, 10:03 AM

Yes, because it disables dxvk

dry-scarlet•6/2/25, 10:04 AM

Hmm, that sounds like a power management issue more and more but i remember running that game full perf like a year ago

dry-scarlet•6/2/25, 10:04 AM

Can you try with Proton 9?

dry-scarlet•6/2/25, 10:05 AM

Remove that wined3d env var
