GTR and new video card

It's been my experience with GTR that I have to shut down a lot of processes
to make it run smooth. I recently upgraded from a 9700 Pro to 800XL, and
even though the frame went up, I still have to use EnditAll to shut things
down before launching the game. If I do that, it's pretty much stutter
free. I use 5.7 drivers.

I think you will find that rFactor is much easier on the video subsystem
than GTR. I don't know why, but I don't see rFactor as anywhere near as
demanding as GTR.

You may have tried these already, but turn "Look Ahead" to 0% and put GTR's
"Special Effects" setting to low. Both are known to cause intermittent
pausing and massive drops in framerate on many systems. Look Ahead affects
performance when turning, and Special Effects cause framerates to drop
dramatically over time.
