Sky Glitching - Rust - Launching Options

Alright first of all, hi everyone!

So what’s going on is that I use this launch option: -force-d3d11 -force-feature-level-9-3 -popupwindow
so I can get better fps, and it gives me better fps like from 30 to clear 60 but then my sky looks so glitchy like if you look at a tree, the tree will be duplicated like 1000 times.

I hope somebody could help me fix this. I’ve already googled it a ton of times but can’t find any help.

Cheers
