As we all know CoD: BO is terrible when it comes to getting good FPS. I upgraded today from a GTS 250 to a GTX 460 and i'm seeing no improvement. In fact, my config during the GTS 250 ran smoother with a higher frame rate than when it was used with the GTX 460.
The drivers are installed properly and the video card itself is fine. I've heard some say that BO has compatibility issues with Nvidias 400 Series.
All in all, i just need some insight, whether it be opinions that were spit balled or based on personal experiences.
It runs exceptionally well with other games. I was getting at the minimum of 75 FPS in Crysis 2 and maintaining around 80-115. But in BO, it normally stays around 50-60 and doesn't hesitate to drop down into the 30-40s
