Windows 7: LOSS of proformance on 7

So I've bean using Windows 7 for a few months now. I decided to run FRAPS to see what kind of frame rate I was ACTUALLY getting. I was disappointed with the results (could have swear they use to be higher), so I ran those same benches on the old Vista install. They where about twice what I was getting on Windows 7. I have all the right drivers, and I have AVG anti virus.

I haven't bean keeping the Vista install up to date, but it seems to be doing better. I don't understand. I've tried updating drivers and everything else that updates... Can't figure this out. If it is useful, I could post the DxDiag.txt specs.

I don't think the fact that it is the 3rd partition on my 1TB hdd should matter, does it?



Core 2 Duo 8400
Nvidia9400 Chipset Gigabyte Motherboard
EVGA 9800 GTX+
6gb of ram (1 gb dedicated to the 9400 on board graphics card)

1TB hdd, Windows 7 install starts on a partition that starts in the last 1/4 of the HDD. Vista is in the first thing on the HDD.

Thx

What drivers are you using? what games were you benchmarking? What fps were you getting?

Benches in Windows 7 should be roughly equivalent to those of Vista. After all, Windows 7 is just Vista refined.

But digital is right, you left out some pretty valuable info.

Idk why, but in my experience I get better gaming performance in Windows 7 than I did in Vista. Nothing too spectacular, but I can usually bump up the graphics a setting or two on 7

about 30 fps or less on L4D Windows 7 vs 50-60 on Vista

15-25 on Crysis Wars on Windows 7 vs 30-40 on Vista

a few others, but I haven't recorded anything.

Could the fact that I have 2 different graphics cards be part of it? If I disable the onboard graphics card on the motherboard, could that improve performance (My screen is plugged into the 9800)

I tried Windows 7 because I heard there was better performance on Windows 7, but I'm not seeing it.

I'm using the lastest nvidia drivers available. I even uninstalled the drivers and reinstalled them. Still no proformance boost.

Which build of Windows 7 are you using?

I can't even play games in Windows 7. I think it's a DirectX thing.

At first I couldn't either, the game would come up then stop responding. I solved that by downloading the latest directX from the website(google directx download, that should take you to it) then I updated my graphics drivers, and all was good. maybe you could see if it would work for you

I installed DirectX 9.0c, but the drivers that come with Windows 7 are better/newer than intel's drivers. Like, they are intel's drivers, but intel doesn't have the version I have on their website.

Yet another reason to dislike intel...
