Slow peformance index in windows 7?
Bearing in mind my old graphics card, Nvidia 8800GTX scored 5.9 for gaming graphics on Vista, when I upgraded my PC and brought a Nvidia 280GTX 1GB, I noticed a big performance increase running things like Oblivion etc with everything maxed out.
So I'm a little bit surprised that it only scores 0.1 better on Windows 7
Processor Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz 7.4 6.0
Memory (RAM) 6.00 GB 7.5
Graphics NVIDIA GeForce GTX 280 7.9
Gaming graphics 3070 MB Total available graphics memory 6.0
Primary hard disk 218GB Free (250GB Total) 6.0
Windows 7 Ultimate
I tried a fresh install of Windows 7, ran a performance test without installing any updates or s/w, this time Gaming was 6.5
I then did a windows update and let it install the Nvidia Prerelease WDDM 1.1 drivers.
This dropped the gaming down to 2.0 ????? (normal graphics remained at 7.9)
I then installed the 181.20 drivers (as I had originally before my first performance test) and sure enough, it's back to 6.0
