Graphic Card Performance Lost switching from 64 bit from 32

[DnaAngel]

Oops thread title is wrong i mean switching from 32 bit to 64 bit.
Okay so im working on a side project PC and i just upgraded the OS to Win 7 Ultimate X64 from Vista Home Premium X86

Build is:

Intel Pentium Dual Core E2200
3Gb PC2-6400 RAM
HP 2028h Mobo Q33 Chipset
PNY Geforce GT 430

When i was running Vista on it i was getting a 834 Passmark 3D Graphics Score and 53 FPS average on the complex test using the 32 bit version of Passmark Performance Test 7 and i also received a 5.9 Windows Performance Index Score

Okay now that i have Win 7 Ultimate 64 bit i installed obviously the 64 bit variant of Passmark and received a 682 3D Graphics score and only got 40 frames average on the Complex test YET Windows Performance index now rates GFX at a 6.7 now?
I havent tested any games yet on it i was hoping to fix this FPS issue.

Other things to note on the HP website ( PC was given to me free at work and its a HP Dc5800 Microtower) dosent have drivers for my particular OS they do infact offer drivers for WIN 7 pro, enterprise, home premium and basic. Same as when i had vista they had all other versions but what i had but i was able to get the home basic drivers to work fine and in that i flashed the bios and installed the Chipset drivers. now when i go to the Chipset drivers on both Pro and Enterprise i get a incompatibility message and it closes and yes i clicked on 64 bit. i could try to install the 32 bit chipset drivers but i would assume that would hurt overall system performance..cause other then GFX dropping i did infact gain +300 score on CPU and +200 score on RAM.

What is causing this issue? Or is thier even an issue at all like i said i went from a 834 score down to a 682 score in passmark yet i went form a 5.9 Windows index score to a 6.7?? hmm. I did everything the same as i did in the vista install, latest updates, lateast drivers, and optimized background processes down to 28 in win 7 ultimate and 33 in vista home premium. what do you think is affecting the performance and what can i do to fix this. My nvidia settings are optimized as well as all C++ runtimes installed. I am also using the 64 bit drivers for my GFX

Hi and welcome to seven forums.

Well the reason your wei changed is due to the fact it only goes up to a max of 5.9 in vista and the max in windows 7 is 7.9 which therefore makes the scaling different.

Regarding passmark, well I can only assume it's something like the 64 bit version is more demanding? Only a guess really.

Looking at the average for you GT 430 on passmark it scores pretty much what you are getting so I don't think its anything to worry about.

Cheers
