Crysis on High settings with Dx9 mode:
XP: Average 40 fps
Vista:Average 34 fps
7: Average 18 fps! (with both 32bit mode and 64bit mode)

oh really?

You could be running Crysis in dx10 mode 'high' whereas in XP only on dx9 'high'. Same for BFBC2
I was running it on Dx9 mode in both Vista and 7.

Video card are unified driver stack. The only difference between windows xp 32 bit drivers and windows 7 64 bit drivers is that they are compiled on different compilers and draw in different dll's and make different system calls. As well as the new expanded functionality.

This is all windows 7 and vista being horrible. So upgrade so windows 8 can come out and you can have more needs and upgrade again.
Oh and read plenty of hardware reviews. I was expecting around 17 to 19 fps when I bought a 5550 gddr5. But instead I got 32.
Published test is 1274x708. My run is 1024x768 for 13 percent workload reduction.
15fps average x 1.13 = about 17 fps. What I got was about 32 fps. Oh and bfbc2 is a real cpu hog. Here it is gently warming a 2250mhz declocked old deneb dual core.
Face it people hitting 100 percent cpu and gpu usages under windows 7 is beyond fixable. All you can do is throw more and more hardware and speed at it as it's a blackhole of financial and computer needs.
