Crysis Warhead lagging in 32-bit system

hey.. I have a very serious lag for crysis warhead at about 8-20 fps.

my system is as stated below:

Intel Core2Duo E6750@2.66Ghz
Sapphire HD 4870x2 2gb
Asus P5Q3 DDR3 Motherboard
2GB DDR3 RAM
160+500GB SATA HDD
800W Gigabyte Psu
Vista Ultimate 32-bit

My settings are enthusiast with motion blur turned off and resolution used is 1440x900 (19" monitor) with no AA.
My catalyst comes with the card (v8.9)

Should I upgrade my catalyst? or should I get a better processor? such as Q9550 for better performance? I'm not planning to OC coz i don't have enough cash for a new PSU..


Regards,

Jason

    by all means.
  2. +1 for updating catalyst

    though i would also upgrade to at least 4GB ram and 64bit Vista (or if you can wait until Win7)

    Waste of time and money upgrading to 64bit for gaming.


    Crysis 64 vs 32
  4. Get more ram.
  5. I had the same problem with a Ati radeon 4850x2, my setup had a quadcore and 4GB ram, I first intalled vista ultimate 32bits and it was horrible, 15-20 fps, then when i checked my ram it was only showing 2gb, that was because 32bits can handle up to 4gbs of memory (including GPU memory).

    So i had 2gb of ram, 2gb of video ram and vista using 35% of my 2gbs of ram.

    what worked for me was moving to 64bits, it takes all 4gbs now and vista only using 20%, I dont think you can run crysis at max settings with 2gb ram even if it is DDR3 (someone correct me if im wrong, but vista takes the same % regardless DDR2 or DDR3) get more RAM and try 64bits and...

    first of all try to update your drivers lol :)
