I have already submittted this question earlier today (Please see the next section regarding my original question; posted earlier today on 10-21-07 PM), Question ID: 22907629  and an expert comment from younghy or Vic (Rank:Guru), has asked me to submit this issue to the "hardware guys". He askes and maybe a hardware expert can answer, "I wonder if the driver can 'pull' any dedicated RAM away from the basic system?" My question Is, is this possible? ...is that what is happening and why my Windows Vista Performance Index dropped significantly? Please reply.

Original question:
Hello. I have a concern. Don't know why, but this doesn't make any sense to me!!! My Windows Vista Performance Index score on my graphics component has dropped!!!!! From a 4.3 to a 3.3!!!!!! This is AFTER, YES AFTER I installed the latest driver (from a download from the Sapphire website) for my  Sapphire ATI Radeon X1650 PRO video card a few days ago. Windows Vista Performance Index detected a change in hardware when I went there. I clicked to update to HOPEFULLY SEE A "HIGHER" SCORE!!!! From what I can recall, the other scores seem about the same for other components. Gaming graphics component is a 4.3, about the same I believe. Right along I have had no drivers installed for this video PCIe card, using the Microsoft Vista default video drivers, I would presume. I THOUGHT SURELY THE SCORE WOULD OF GONE UP A LITTLE!!!! NOT DROP SIGNIFICANTLY!!!! WHY???????? Please tell me out there if anyone has a reason to this?????  PLEASE REPLY! It sounds like putting the necessary drivers can HURT YOU (the operating system I mean)!!!! Maybe Windows Vista generic drvier(s) are BETTER?????

I would think you are doing to know about my system.:  To elaborate on my hardware, I have Intel P4 Proc. 640, 3.2 GHz, 800 MHz FSB, 2 MB L2 Cache, with HT Technology. I have the Intel D915PBL motherboard. This is a custom-made computer. I have Windows Vista Ultimate on a Maxtor SATA II/300 Internal Hard Drive (7,200 RPM). THe hard drive is connected to the SIIG SATA II PCIe card controller that is connected to this motherboard's PCIe (x1) slot. There are 2 storage controllers: Microsoft  iSCSI Initiator and the Silicon Image Sil3132 SATALink Controller. The IDE ATA/ATAPI controller is the Intel 82801FB/FBM Ultra ATA Storage Controllers - 266F & Intel 82801FR SATA ACHI Controller. I have (4) 512MB Corsair DDR2 240-pin Memory Modules, total 2048 MB. For video card, I have a Sapphire ATI Radeon X1650 PRO 512 MB DDR2 PCIe Card. Any questions, please ask.

The quick answer is no, not on this card. If the card used shared memory the driver could affect how much shared ram it uses. This card doesn't use shared memory all 512mb is dedicated. I would say its a driver problem, remove the new driver and install a prevoius version and see if you still have the same problem.

why do you think it takes Ram a way ""Wonder if the driver can 'pull' any dedicated RAM away from the basic system" ?  i saw nothing in your Q that indicates it.
Personally, - i don't trust the Vista Performance Index ; i had a reazding on my video that was at 1.0, and WITHOUT installing, or modifying, next time it went up to 3.5 ... go figure

Don't believe the vista performance index as it's not really correct. The point is, do you notice any decrease in performance in your games after installing the new drivers? if you haven't then there's nothing to be worried about.
