Rust Issues

Howdy.

Today I am having a severe issue with Framerate in Rust. I get only 6-20fps max in any server. I usually crash whenever i fire a bullet.

I am running a Ati Rhaedon 4200, fully updated.

I get this error in my f1 nearly every half second, i feel as though this is the culprit.

rendertexture.create failed, unsupported.

Tips or tricks?

Merry Christmas.
