So recently, I've began to notice this odd graphical issue while playing Halo CE. Earlier today when I was playing Soi's Singleplayer Adventure, I began to notice some slight flickering across the screen, usually whenever there's a lot of enemies shooting plasma weapons. Here's a video where you can see slight screen flickering: https://www.youtube.com/watch?v=Xcwz_8ubyCM

Anyway, I just want to know if anybody else is getting this issue on this mod.

I don't know if this graphical error has a name, but I would call it polygon stretching.

A lot of old games played on newer hardware seem to have this error. Maybe tinkering about with the compatibility modes could work.
