Torque X 2D - running slow

I'm new to Torque. I recently installed Visual Studio 2008, XNA, and Torque X 2D. When I run the demo TankBuster game (in debug or release), the game runs slowly (choppy). I then ran the game as just the .exe. It too was slow - not as slow though.

Based on what I read, it might be my graphics card slowing me down. What is the minimum Graphics card I should be trying to develop games in Torque for?

Is there anything else I need to look at?

Currently running:
Intel Pentium 4 CPU 3.4 (2 CPUs)
2G RAM
Integrated graphics card - S3 Graphics: supports 9.0c, 128MB RAM, direct 3d tests completed successfully


Thanks in advance!
