I get better fps on 32bit crysis than on 64bit why????

There's probably some settings that you need to adjust, there's alot of variables that can come to play, from the way you described it. It can be CPU usage, where you are in-game when it happens, current graphic settings, on-going processes while your playing, drivers, ingame resolution, graphical settings/current released drivers...a 5 FPS difference is normal to me, I get FPS fluctuations depending on which direction I'm looking in on the Crysis engine.

Look here this is what i notice is different now i bet u can tell which is 32bit and 64bit

Drivers for x86 are normally a little more refined and give better performance, also under x64 you have a x86 translation layer that gives a small performance hit.

also under x64, you may have a few more services running, checkout www.blackviper.com for optimizing these.

Too be honest though, it shouldn't be noticeable if game configured correctly and I for one wouldn't go back to x86.

Your AVG not got the gaming mode, I use AVG internet Security and I have it?

Also, ATI drivers now at v10.3, which will give your card up to 6% boost under Crysis.

thanks yh i've got the 10.3 drivers now and my avg has got gaming mode enabled but do you reccomend getting the whole ati catalyst package with catalyst control mangaer or just the display drivers because thats what i've got always  

i dont think u neet catalyst control center...its just a waste of space....what matters is the driver only
