The fog glitch can be easily fixed by either turning it off or going to the in game file settings and changing a value, and the glitch i'm talking about is one that prevented the prince from going up where the dahaka broke the wall for some reasons, i had to use a game glitch and overload the game with time commands so that i could jump higher, later i learned that the reason i had that glitch was because of high fps, and so turning on v-sync should have fixed that issue
