Sudden drops in FPS?

[JohnElightening]

I'm running at Bristol 2012 and this is my first time playing in a couple of days.

In replay mode the cars stutter all the time. I press the F key and it'll be at 60 FPS, and then it'll go down to 30 in a split second, and back to 60. This happens all race. It, however, doesn't happen at all when I'm racing, just in replay mode.

I did start playing another game on my computer, Civilization 5. It and NR2003 are the only computer games I've ever played on this computer.

Thanks for any help.

EDIT: Nevermind. A quick restart fixed it. I wonder what was wrong, but it works perfectly now.

I had a similar problem where in a replay with a lot of cars in view the frame rate would drop into the 30's, I fixed it by going into the player.ini and changing the enable_CarMegaShader and enable_ShadowVolumes both to 1.

This gave me 20 fps gain in replay, and also a bit better in the game as well but I don't know if it will work for you though.
