DXVK Choose GTX 1070 Instead RTX 4070 Super
whenever i tried to change settings in windows to default RTX still uses GTX for play the game

The game is Tom Clancy's Ghost Recon Wildlands, and it's really playable with DXVK ( i have tried to take off my GTX out of PC and let the RTX alone in my PC)

Update: the game playable with setting env but, when my hdmi at GTX the game run capped 30FPS, if i change it to RTX the game flawesly run at 4k60FPS

can you fix this please?

Seems the new variable is not applied to the game.
New system variables only apply to new programs launched from explorer. Programs already launched and their child processes are not affected. So if you didn't restart the game launcher, then the game still gets old variables from launcher (its parent process).
The easiest way to solve this is REBOOT after save system variables.
You may also need to read this: https://serverfault.com/questions/8855/how-do-you-add-a-windows-environment-variable-without-rebooting

You can also use Process Explorer to find the game process, double click it and check its environment to see whether your variable is taking effect.

So this is probably not a DXVK bug.

Already REBOOT but still nothing, unless my HDMI on RTX

Which issue are we talking about now?
If it is the FPS then check your monitors refresh rate or the refresh rate option in the game. If the vsync option applies a double vsync then the FPS will be half the set refresh rate when enabled.

Issue when hdmi on GTX but game run with RTX FPS Capped 30, unless the HDMI on RTX, because i want all my display handle by GTX and gaming only using RTX

Driving 4 4K Monitor at once will eating so much vram so i use my GTX to handle it

Is there still 1070 in d3d11 logs? I see 1070 initialized for DXVK in yout logs.

info:  D3D11InternalCreateDevice: Maximum supported feature level: D3D_FEATURE_LEVEL_12_1

Issue when hdmi on GTX but game run with RTX FPS Capped 30

Can you confirm whether it's a GPU bottleneck? (At least one GPU reach over 90% in taskmgr)
Also check your monitor refresh rate.

i don't know, the log generated from root game folder where i put these 2 files

the gpu is not bottleneck as other games can use RTX via windows settings normally, BUT if i hook up HDMI to my RTX it's work very well, also my monitor refresh rate is 60hz, i play all games with just 1 display 4K60 with my RTX

[qinlili23333]

BUT if i hook up HDMI to my RTX it's work very well

connect all monitors to RTX, launch game, connect some monitors back to GTX, drag window to monitors on GTX.
Can you test this?

yes like i said, 1 monitor that i used to gaming i connect it to my RTX and it works perfectly, but yeah 4k monitor does require 500mb-1gb Vram

If you just need approx 1g extra vram, you can just disable steam and other chromium based applications to use GPU acceleration. Deleting libegl.dll and libglesv2.dll from those applications can force them to use software render, which save vram with performance downgrade. But you don't need a 240fps steam, right?
