Halo Combat Evolved PC Campaign Glitches

Hello everyone, I have recently done a new play-through of halo combat evolved on my PC. Throughout the campaign i have encountered various campaign cut scene glitches, Specifically texture glitches.
For example, various lights on AOTCR and Two betrayals clip in and out of the walls behind them
some of the far away terrain in 343 GS is just not there at times (pictured in this (https://www.youtube.com/watch?v=q-1S_Dh--14&t=20s) link at around 19 seconds, but stuff like that happens throughout the level
the textures for electrical impulses(like when 343 guilty spark interacts with things) are not even transparent, just black. (pictured in this (https://imgur.com/a/w3xLx) link).
Is something wrong just for me,or is this just due to gearbox screwing stuff up with the port? Any help would be appreciated. Thank You.
