Need some techie help

(Just joined the forums)

Long story short I decided to install Rust again after about 9+ months away from the game, tried altering some settings to put it on low (cos my pc is a hunk of junk).

After I put the settings how I used to have them I kept getting these colour boxes coming up and I have no idea how to fix it (see attached link)

If anyone can help that’ll be a huge help <3

That looks like a graphics card that want to get out of your machine.

Funny stuff apart, what is your system specs? CPU, GPU, OS, Ram, etc.

To me that looks like your graphics card is on the verge of dying, or being stressed to the absolute max. If you post your specs it would give us a better idea of what the problem may be though.

just because it hasn’t been mentioned, are your drivers up to date?
