I think there may be some general confusion between ‘ray tracing’ and ‘raycasting’.
Thanks to Nvidia, ‘raytracing’ now means ‘doing an utterly absurd amount of raytraces all the time in order to have slightly more accurate relfections and light physics’.
Whereas, at least the lingo I’m familiar with, ‘raycasting’ is just like… a single ray, maybe a couple to form a frustrum, or maybe one that follows some bouncing vector math rules, to do a fast simulation of a bullet trajectory, or maybe its just attached to the player to tell the rest of them game something like… the player is on the floor, the player is standing infront of a wall or a short stairstep or climable ledge, etc.



























Ok, I just did an entire write up and then shit canned it half way through because there’s a question I need to ask.
… which… ones?
Because PopOS has its own way of doing Nvidia drivers.

If you are manually trying to do your own Nvidia Linux driver install, on PopOS, that could cause some nonsense problems, where you would be in a state of essentially having 2, or kinda 1 and a half… sets of drivers installed at the same time, which would/could lead to bunch of extremely esoteric configuration problems, possibly including what you’ve reported so far.
