GTA IV Lag Windows 7 on iMac

I get a slight lag in GTA IV when running in Windows 7 Ultimate 32 Bit. I have it installed on my iMac (http://store.apple.com/us/browse/home/shop_mac/family/imac?aid=AIC-WWW-NAUS-K2-BUYNOW-IMAC-INDEX&cp=BUYNOW-IMAC-INDEX) (the 21.5 in. 3.2 GHZ model) and I've tried the Disable Windows Event Log and Defragmetning the GTA IV Folder, but it still has the lag. I don't know what else to do. I think my computer is pretty decent for running games, but it still sucks with GTA IV. Also, no matter the Graphics Settings, it still lags. Ideas?

...Windows 7 Ultimate 32 Bit. I have it installed on my iMac...3.2 GHZ model...no matter the Graphics Settings, it still lags. Ideas?

How many cores or total threads is your processor? IV is a CPU hog. 3.5+Ghz is best but it has to have at-least 3 execution paths so a quad-core or 2+2(HT). A dual-core with no HT will not cut it usually.

EMULATING WINDOWS ON A MAC ALREADY KILLS PERFORMANCE. get a windows based pc with decent specs, problem solved. simply put macs are still not meant for gaming at this point...

These are my specs:

 

Processor: 3.2GHz Intel Core i3 processor with 4MB level 3 cache; supports Hyper-Threading

 

Graphics: ATI Radeon HD 5670 with 512MB

 

RAM: 4GB (But only 2.99GB used in Windows 7)

 

OS: Windows 7 Ultimate (SP 2)

These are my specs:

 

Processor: 3.2GHz Intel Core i3 processor with 4MB level 3 cache; supports Hyper-Threading - halfway decent

 

Graphics: ATI Radeon HD 5670 with 512MB - not a gaming card and little ram by todays standards

 

RAM: 4GB (But only 2.99GB used in Windows 7) - so its 32 bit windows?

 

OS: Windows 7 Ultimate (SP 2) sp2???? sp2 ???? really? how as we do not have sp1 yet

That's not true. He is most likely running bootcamp, which is nothing more then a dual booting system, Windows 7 would have native access to the imac's hardware.

 

That being said, the specs aren't great, but he should be able to run IV at lower settings without lag. Probably GPU drivers issues.
