First, please fill in issue template.
command with commandline.txt
Why are you using commandline.txt for this?
You should either use environment variable or dxvk.conf to configure this.
If you want to set this with Steam command, see my guide on PCGW about how to use advanced %command% skills to override Steam launch options.
For fallback if you want a quick workaround if method above is a bit complex for you, you can also disable dGPU in device manager to force iGPU if your monitor is connected to iGPU. However I must remind you that disabling dGPU in device manager doesn't mean shutdown the power to dGPU, instead dGPU will stuck in C3 (same power consumption as normal idle) instead of C8 (no power consumption) which will make your battery exhausted faster. Disable dGPU in BIOS if supported can make dGPU totally off.
i also tried inputting the command into Steam’s Launch Commands and it still doesn’t work
That doesn't work on Windows.
Like qinlili23333 said, you need to set up the config file or set it up as an environment variable.
DXVK_FILTER_DEVICE_NAME="x1 2025-02
I am trying to set DXVK to use my Integrated GPU, particularly to increase stability and performance for older titles
Windows 11 23H2
iGPU: AMD Radeon 780M
dGPU: Nvidia RTX 4060
Ive tried using the "DXVK_FILTER_DEVICE_NAME=" command with commandline.txt to use my AMD Radeon GPU name but it does not set it. Setting the title to use the iGPU in Windows Graphics settings doesn’t work either
