I can't seem to get better than 60 FPS(with FRAPS) in NFS:Carbon with my current setup:
AMD 4000+ s939
8800 GTS 320
2 x 1GB Corsair
Thermaltake TR-2 500 PSU
Win XP Home
I've o/c'd the CPU to 2.8Ghz with no improvement. Windows CPU usage history graph in task manager shows 100% CPU usage while running the game. Turning down some of the eye candy settings in the game also doesn't help.
I guess this means my CPU is the limiting factor here? Game is still playable though. Thought I'd get more FPS though with this graphics card.
Sounds like Vsync to me too. It basically limits the framerate to the refresh rate on your monitor.
NFS:Carbon is a GPU bound game, CPU speed matters little, so it's definitely not your CPU. I did a test between 2GHz and 3GHz on my E4400/8800GTS 320 setup and I got a 1fps difference (56 vs 57fps) so yeah. This is @ 1680x1050 max details with the 8800GTS 320 heavily overclocked.
However, don't go crazy on the settings on a 8800GTS 320 at high res, especially if it's not overclocked. Motion blur is a real drain on performance, you get a ~20% framerate boost turning it off. Besides, it looks crap anyway IMO, you can't see anything once you get up to speed.
I didn't know that KyleSTL. Does that apply for all monitors or just LCD's?
It applies to all monitors; the refresh rate is simply the number of times the image can be changed per second. Enabling Vertical Sync simply locks the framerate to your monitor's refresh rate eliminating image tearing.
