Doppleganger said:Maybe you have some background process that's running, causing your FPS to drop suddenly. Something like an anti-virus prog or similar. Maybe it's just the supersampling with the GTS and the more powerful GTX copes with it better. For example I get a far higher min FPS score than pastymuncher who's running a more powerful cpu than I am, but with a GTS.
Cheers for the reply.

I'll try it with Supersampling off and see what happens. Defraged both drives as well last night. Although they were only 2.0% and 0.2% fragmented.

The only background process would be NOD32, but we'll see what happens with Supersampling first.
