It will depends on your platform. So, for a laptop with AMD cpu and an old NVIDIA gpu I was able to get the same as in Windows performance
__VK_LAYER_NV_optimus=NVIDIA_only __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia gamemoderun %command% --launcher-skip -skipStartScreen
After a restart the fullscreen resolution will be setted-up
Spend about a day to figure out the problem with low fps (~17 not depending from any of the graphics/display settings) in the city. The following tinkering parameters (from random nvidia developers thread) helped me to solve this issue :)
This game will work fine on a desktop computer. However, need additional flags on laptops with dedicated graphics.
DRI_PRIME=1 gamemoderun %command%
I had black area at the bottom of a screen. In order to remove it, you may need to run the game with dedicated card or as a solution for integrated graphics:
- Switch mode in display settings into Windowed;
- Apply changes by returning back to a main menu;
- Press 'Alt + Enter' to enter again into borderless mode, but without black area for now.
On Fedora, you are supposed to switch the GPU manually to a dedicated card. It runs with an integrated one out of the box.
Firstly, I came up with a solution to run the GoG launch script in a game root directory:
switcherooctl launch $PWD/Psychonauts2.sh
Then, I found a much simpler solution with the DRI_PRIME flag, and it works like a charm ;-)
