That is called artifacting. Usually caused by your gpu being too hot. Try enabling vsync in your ingame options, and type ingame /maxfps 40.
Also, on your launcher options, under advanced command line, enter "-perframesleep 10" without the quotes.
This command lessens the load on your GPU. If those dont work, post back with your dxdiag log
Screen tearing is caused by VSYNC not what was show in the picture. Turning on VSYNC will just sync refresh rates and limit the framerate to vertical.
Those are polygons not rendering properly. I'd guess shader issue but also an effect of heat strain on failing GPU. I'd guess shader issue since that card is only running shader 2.0 I beleive this game requires Shader 3.0
What exactly does -perframesleep 10 do and do you have any command or console commands to control rendering variables? Is there a list of commands I can find somewhere?
Thats odd, you say If they are off they aren't an issue When set to OFF in STO they are OFF, but of the Forum it only showed you as saying.
Thats because I was writing a reply to another thread but in the wrong thread and I changed it at the last moment as your issue is with shaders and another was having problem with mysterious black dots I noticed I was in the wrong thread then saved it quickly to try and write a proper response sorry lol its 5:20 am and I havent slept and my back is KILLING me.
