I moved all my hardware to a new mobo, Asus P5N-D 750i, and i added a new XFX 8800GT 512M. The old hardware is: patriot 4G 800mhz DDR2, 250G seagate sata 150 hd, pentium d 925, 500w antec basiq. The RAM & CPU is only 5 months old.

I installed a few AV and Antispyware programs and COD4. That's it. I tried playing COD4 and it is running at 6 fps with a few peeks at 20 fps. COD4 settings are 0-AA, 0-AF, 1024 x 768, everything else off or low.

The mobo seems to be runnin fine, but i am a noob with nice mobos. It could be some mobo setting, not sure.

Temps are all under 50C even under load. I didnt notice any burn smell or see burn marks.

Shouldn't this combo of mobo and 8800GT be running at 1600x1200 on high at 70FPS? What the hell?

The old hardware was on a HP with a 7600GT 256M and i was getting 50 FPS. Now this 8800GT can't get 10 FPS.

Any ideas where to start?

make sure you are using the latest drivers for the video card. Im assuming that the move to new hardware included a fresh OS install right? Also, you do have the 6 pin pcie connector plugged in?

It could also be a driver issue, make sure you have the latest drivers and if you do you can try the previous version.
Also, have you tried running anything else that might give you a clue about the source of the problem?

For example, you could try a cpu benchmark to make sure it's not the cpu that is the problem, there could be something wrong with the cpu(some issue with the new motherboard)...

I assumed he must have installed a new OS, since he mentioned installing only some AV and anti-spyware along with the game.

Drivers: i tried the nvidia drivers that came on the disk and the newest from the nvidia site.

OS: yes, new install of windows xp and sp2.

plug: yes the 6 pin is plugged in.

Could my PCIe slot be running wrong speed? how do i check that? I could not find it in the bios.

@DiscoDuck got 3 valid points.

my bet is in the 6 PIN PCIe connector. probably not plugged.

@ Evil - I did notice the CPU running at 80-90%, but it was running fairly cool at around 50c. what else could i run to use as a comparison? I uninstalled the AV and AS and i still had the same 6-20 fps. I also turned off the firewall. same result.

One thing i brought over from the old install was my COD4 profile and all its graphics settings. Could the old cod4 graphics settings cause a conflict?

IF the 6pin wasn't plugged in, i thought it would not post at all.

at lunch i will go home and make sure the 6 pin is pushed in all the way.

Try another game.

Download demos of the most recent/demanding games and compare your results; if it's just COD4 running uber slow, destroy game/profile/everything and re-install game.

If it's ALL games that are uber slow, take card to friends house and test on his rig (or if you have a second rig, even better)... or better yet, get a friend with close to same hardware and tell him to bring his PC, so you can swap stuff in & out to find the culprit.

I aint evil, but today im having a slow work day.

Doubt your cod profile is doing this. Download ·dmark and check if your 3dmark is much below the rest of the people with similar configuration. After the tests there is ussualy a table with rankings and stuff.

If you got a problem with your GPU , 3dmark will surely show it.

just go to www.futuremark.com and Dl 3dmark.

cpu could be a bottleneck or PSu not strong enough. try a stronger psu.

This PSU, 500w antec basiq, was pushing an ATI 3870 a few months ago. Any way to check the PSU?

What about the PCIe speed? how can i check it?

@ Radnor - I will try the 3dmark after work. Thanks.

Even if your playing with the PCIe at 4x the results shouldnt be that low. I saw a review some time ago, it was in THG or Anadtech. Check the bios, you can probably configurate it there.

About the PSU Check your mobo manufacturer, Asus has some nifty softwares for your mobo. Dl rivatuner or Ati tools to check you GPU values aswell. I guess you PSU should be fine. If the 3dmark results come okay, somethings fishy.

It definately sounds like a driver problem, assuming the videocard is getting enough power. Make sure you install mobo chipset drivers first before you install any other drivers. Don't wory if you didn't. Just install the chipset drivers and then video, LAN, sound, etc. Also I remember a few builds ago that the Driver CD that came with my DFI NF3 board had GART drivers. Don't install these if you have them. They decreased my 3DMark performance by 30%.

I used ntune to check the GPU clocks. The clocks were 600/900(1800) just like advertised and the temp never got over 56c at load.

IS this happening in JUST COD4? or all games?

What I meant by that was, test your cpu so you make sure it's performance is where it should be. Like run one of the superPi benchmarks and compare it to that of another cpu similar to yours.

I believe if you run 3dmark both the cpu and the gpu under-performing could pull your score down so you can't just point the finger at the gpu and not look elsewhere for potential problems.

teh_boxzor,
I don't think the cpu would bottle neck the system that much if it was running properly.
Still, he should run some other games to make sure it's not some specific issue with COD4.
