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.

Tried turning off a lil thing called vsync?
Yeah I know... I'm a genius.
You can send your thanks in the form of money, preferably cash. :whistle:

have not tried turning off vsync yet. Will that have a big improvement in my framerates?

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.

Thanks for the advice guys, i'll give it a go and see what happens. :-)

Yes it definately improved when I turned off Vsync.Jumped from 60fps to 90+fps with everything turned on. :-) Thanks guys.

You realize you don't see those frames, right? Your monitor (more than likely) can only display 60fps.

I didn't know that KyleSTL. Does that apply for all monitors or just LCD's?

It depends on the refresh rate of your monitor. 60Hz is a pretty common refresh rate.

That's the entire point of vsync. There is little point to calculating frames that your monitor can't display, so instead it is capped at the refresh rate of your monitor.

You can check the refresh rate of your monitor in control panel->display->settings->advanced->monitor, or probably from the device driver section also.

Of course, none of this prevents you from upping your fps to 90+ for bragging rights, though some might consider you a fool.

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.

thanks einstein4pres. My monitor's current refresh rate is 60hz.So I might as well have vsync turned on. :-)
