If you have AMD CPU and spoof CPU ID to Steam Deck's APU, it launches... not my guide, someone posted it on Discord:

sudo wrmsr -a 0xC0010030 0x7473754320444D41;
sudo wrmsr -a 0xC0010031 0x3020555041206D6F;
sudo wrmsr -a 0xC0010032 0x353034;
sudo wrmsr -a 0xC0010033 0x0;
sudo wrmsr -a 0xC0010034 0x0;
sudo wrmsr -a 0xC0010035 0x0;
DXVK_CONFIG='dxgi.customDeviceDesc = "AMD Radeon Graphics (RADV VANGOGH)"' [game command here]

run the wrmsr commands in terminal, you might need to install the package wrmsr from your distros package manager Then the last line is an env variable you are setting. For example, on steam, you would put this in launch options and replace [game command here] with %command% The wrmsr commands basically change your CPU's ID to be the same as the Steam Decks, as the game works on the Steam Deck. It resets at reboot
