So yeah, pretty wierd.

I don't know what to do about that, and no, I don't have an ancient
piece of wood computer, I changed my graphics card, and now it doesn't work,
It worked on my old radeon though.

Specs;

Windows 7 Ultimate.
Ram: 4gb
CPU; AMD Phenom II x4 905e
GPU; Nvidia GeForce GTX 560 Ti, previously ATI Radeon 5700 HD Series.

Last time I checked, I got 60 fps on TB.
