It depends on who makes your video card. ATI and Nvidia both have utilities in their driver packages that will let you see your GPU temp. If you have a modern machine, you might also be able to try RealTemp, which is what I use for overclock stress testing.
lower grapics to minimum and see if it helps... Turn half resolution on, that seems to fix many problems except not being able to see clearly.... If ur useing a laptop i sugjest trying a cooling pad when u play STO...
