Is it a switch in gnome sw or settings? If not it's not pretty easy
That really doesn't sound right, I have a 930m and it ran GTA V on med-high 720p (on Windows though..), the game itself is ps3/x360 era so you probably have a problem with the driver or maybe double check it's running on dGPU
Those tiny legs though 😭😭
I've tried Arch32 a while ago, the project isn't that well maintained (like I appreciate they're trying), I've had MX Linux before, worked great, just a bit outdated, I moved my 32bit machine to Void Linux, it seems to have the best support yet ! I'm running cutting edge kernel and dev tools on that old fart

I followed the steps in the installation section then installed nvidia-prime from Arch repos, prime-run works (I set up a custom menu entry of some apps that I want to run with the NVIDIA card) , the Vulkan demo detects and runs on the NVIDIA driver even without running with prime-run (afaik Vulkan does a good job detecting all the GPUs installed), I have the same setup as you do, Plasma with (Intel iGPU + NVIDIA dGPU)
I think gitui deserves to be on the list
