Does tS rely on the OpenGL capabilities on the graphics sub-system? I know it renders in real-time using DirectX.
I can't say for sure but maybe an update to your video drivers or an OpenGL bug fix would help. Out of the mainstream video card manufacturers nVidia does a pretty decent job with OpenGL so you shouldn't have too many issues with their hardware unless it's one of the cards they no longer develop the drivers for.
One possible problem is that you are using a 'shared memory' graphics device EG. Some software has major issues talking to the graphics subsystem when it shares main system memory. There are some settings in your BIOS that affect the way that main memory is used and addressed. You may have some luck looking at those too.
I have 2 heavily CPU and graphics intensive games that simply refuse to run without random hanging when used with onboard 'shared memory' graphics cards.
Hope this helps.
