Brand new to windows 7 and 64 bit, got it based on the advice of my tech guy at work. The problem is that gaming performance has suffered. 3dmark 06 XP Score = 12930 Win7 Score= 12170. World in Conflict avg fps XP= 43 Win7 Dx9= 40 Win7 Dx10=34, all same settings. I did not make any hardware changes and installed updated drivers and patches respectively. Have not had any crashes or other problems so far.


Hardware: BFG nforce 650i ultra, 8800gts 512, 4 gigs OCZ Reaper ddr2 800 (oc'd to 924), intel dual core e2160 1.8ghz (oc'd to 3.4ghz), 550w PSU

If this is just normal thats fine, just want to make sure there isn't wrong with my system

This is normal. XP is faster than 7. Some people still try to argue that fact, but it is true. Its not HUGE. Its not as slow as Vista but it is still slower than XP.

Thats about 10% percent slower, which is what benchmarks have been showing since 7's release.

Why is Dx10 so much slower, I thought it was supposed to be the same if not faster? I know this may all be newb questions, but I have not upgraded anything for at least a year so I am not as informed as I used to be. So bear with me

Its not DirectX, its the OS. Vista is a lot slower than XP. 7 is a little slower. Thats reflected in your results.

I am with you on the 10% between XP and 7. I was referring to windows 7 averaging 40fps with dx10 disabled (so using dx9) and averaging 33fps with dx10 enabled in World in Conflict. That is the part that concerns me.

DX10 improves visuals, which will decrease FPS a bit, but actually you are on pretty out dated hardware.

Oh i know, funds are just focused elsewhere and my xbox buys me some time with some games. Just did not expect a 7 fps difference, was more thinking a couple if anything

DX10 runs noticeably slower than DX9 on the same hardware, benchmarks have shown this over and over again, so no surprise there.

Well looks like I will have to pick and choose the games I run Dx10 with. I know some games run well on my comp and I will be able to get away with is (Bioshock 2). Just will have to wait till i do another system build. Sounds like I need a total rebuild to get with the current requirements

It's one thing to see these performance drops in benchmarks, but are you really seeing a slowdown during game play?

Also, most games that support dx10 also have a dx9 mode, so you should be able to switch to dx9 if the performance difference bothers you.

Well in world in conflict it was a difference between playable and getting close to having problems. I just installed a GTX 260 that I got for $50, but only saw a 6-10% performance increase in benchmarks and games, respectively. So I think I have a bottleneck on my CPU with the new card (3dmark06 went from 12170 to 12990)

There could be another thing you mite want to look at. I dunno if this actually applies so flame on ppl haha. Since u OC-ed ur cpu and using a nvidia chipset, what could end up happening is your chipset is getting hot from the OC which usually will reduce speed to deal with the heat. But the thing part of the communication between the graphics card and cpu go thru the chipset. This might be the reason you saw only small performance bumps.
The other thing is are u sure that ur cpu is stable at tat clockspeed? I found that when i OC my q6600 over 3.0Ghz it runs slower than it did on 2.8ghz. So this might be another thing you'll wanna look at

It was stable and CPU score increased in 3dmark06 when I did the overclock. Can windows 7 cause stability issues on an overclock that was fine in XP. My scores do vary more in 3dmark and world in conflict than they did before I installed the gtx 260 from the 8800 gts that i had earlier in this post

32 bit and 64 bit OS are fundamentally difference from what i understand, what is stable is windows xp doesn't mean its stable on 7. Usually if ppl dual boot and want to OC they usually dun peak out. if u know ur max is like 3.2 ghz bringing it down to 3 or 2.9ghz might make both OS' more stable

its because its 64bit and xp was 32bit 64bit os needs to run emulation to get 32bit apps and games to work this cuts the performance by 3-5% at least
and 7 uses more ram then xp

Doesn't need to run emulation. Where did you get this?

WoW64. "an emulation layer that enables 32 bit Windows-based applications to run seamlessly on 64-bit Windows."
It also creates some additional files of the app/game in order to run the 32bit software.

I see what your talking about. But Wow64 is not emulation per se. 32 bit instruction execution is native to X64 processors. Some 64 bit CPU like the Itanium are really emulated.
