I'm having a bit of an OS problem here.. I recently installed Windows 7 64-bit (6.1, build 7600) because I read and heard that it supposed to be much more efficient than XP (which I had before), and that it was going to give me a performance boost for my games (especially since I got the 64-bit edition and it would take into account my full 6 gigs of RAM and not just 3,5 like XP 32-bit)
Well as it turns out, it's quite the opposite. I'm actually suffering pretty substantial performance drop compared to XP. I scored 11% lower in the official FFXIV benchmark, but then in the actual game, I dropped from 35-38 FPS in open areas to around 23-29 FPS according to Fraps. That's a HUGE difference, and not in the way I was expecting!
I reinstalled CRYSIS to see how it affected another game and it's the same thing. On the same settings as on XP, a comparable drop as with FFXIV. WTF??
Could it be because those apps are not 64-bit native, the system has to do some sort of conversion to compensate, hence the performance hit? (that hardly sounds like it makes sense but I'm desperately trying to understand what's causing this.)
Or am I doing something wrong? Is there something I can tweak in Win 7 that I don't know about? Because I'm just about to revert back to XP honestly.. And I really don't understand because people were writing (I know I saw it here) that switching to 7 had improved performance for them, not the other way around.
for the record, I have:
Intel Core2 Quad Q6600 @ 2.4 GHz (I know, not super)
6 gigs of Kingston DDR2 @ 667 MHz
GTX 460 (the 1 gig eVGA one)
mobo: ASUS P5N E SLI
OS: Windows 7 64-bit (6.1, build 7600)
and under XP, I was running the 258.96 nvidia driver for Windows XP 32-bit and with Win 7 I tried both 258.96 (64-bit) and 260.89.
I used to score 2591 on the FFXIV benchmark on high settings and now I'm down to 2302.
According to the little Win 7 widgets, when I run the benchmark, my CPU usage is at 71% and RAM usage tops at 28%.
I realize I don't have a top-of-the-line rig; my processor and mobo are three years old. what I don't understand is why I'm getting worse results with Win 7 than with XP when that seems to go against the trend..
Needless to say, any help would be *greatly* appreciated.
thanks in advance!
