Once again the latest 174.xx came out with impressive performance records, although when I close the UT3.exe application, I receive the...

My initial testing with Forceware driver 169.13 in the default SLI performance mode worried me a bit. As a tweaker, I know when my framerates are dipping below 30fps and it bothers me. With the 169.13 driver I had no crashes, but my frame rates were usually in the 40's and that's a bit low for my taste: especially since I have a high-end, SLI GPU configuration. As per usual however, subsequent beta drivers have proven to boost that performance and we haven't seen the plateau yet.

25/11/2008 Forceware 180.60 CUDA betas prove themselves a bit worse than the 180.48 set, but better than previous 180.xx releases with an avg of 62.42fps and surprisingly few frame rate dips with 91.39% above 30fps. You need at least a Geforce 8 card to take advantage of CUDA, so this time I'm SOL.

I've heard around the Epic Games Forums that optimal performance in UT3 is gained by lesser-used SLI rendering modes. I tend to dip below 30 frames per second at times despite the power of my dual EVGA Geforce 7950GT's, so I thought I might test the theory.
