Halo 2 anniversary texture flickering issues

I’m having lots of issues regarding textures in Halo 2 Anniversary on the PC, and I’ve looked up this issue online only to find nothing. I would post a screenshot, but I don’t know how to. The textures flicker all over the place, with rainbow colors. If anyone has any support, let me know! I’d very much appreciate any help! Thank you!
My computer uses a Raedon RX 460.

Hey zombieMAX02,
Did you ever get a fix for this?
I’m having what seems like exactly the same issue. Hitting ‘tab’ & switching off enhanced graphics the only way to make the game playable, which is a real bummer because enhanced looks SO much better (somewhat obviously).
I’m using an AMD Radeon Pro 5500M running Win 10 x64 (Build# 18363.1256)
Any help you (or anyone else) can provide will be greatly appreciated.

you can switch mic cutscene at least so you do get that experiance
