OMFG LOW FPS WITH 8800GTS 640MB

[xoulu]

OMFG I am getting low FPS with my new 8800GTS 640MB. In WC3 I get 75fps with my old video card (ATI x850xtx), GW 75fps, WoW 84fps, and CS 96fps constant and now, I got a $350 8800GTS 640 MB OC and I get 60FPS in WC3, GW 30fps, WoW 18fps, CS 14fps. Help please, this low fps is killing me.

Did you completely remove the old drivers for your old video card?

Also, I would doublecheck your settings, such as your resolution, AA, AF, etc...

 

[xoulu]

yea i did, removed old drivers and installed new drivers. I did check them and it was ok, I just ran 3dmark05 and i got 11,750 on the video card. I dont know why I am gettin such low fps. I think its the drivers but I am not sure. Any suggestions?

 

[DJ_Jumbles]

What hardware are you running? what driver version are you using?

 

[erocker]

OMFG post your damn system specs and mabye someone can help you. :roll:

ZOMG END OF TEH WERLD

 

[monst0r]

my bet is the drivers, or the card isn't being properly installed..try a complete reinstall (taking card out, uninstalling ALL drivers using driver cleaner, inserting card, using the drivers that came w/card)

I did replace the card and reinstall the drivers. Still same FPS.

Here is your problem, you psu isn't powering your card enough. You need a new power supply. Also make sure you have the latest bios for your motherboard. A cheap 750 watt power supply will do. Powertek F5 fits the bill.

 

[xoulu]

are you sure its my psu? cuz its 600watts

 

[4745454b]

You still haven't talked about the resolution change yet. Are you testing with the same res as the x800xtx? Don't forget to force the 8800 into SM2 mode, as thats the best the x800xtx could do.

600W might be enough, but there are bad 600W units out there. It would be nice if you could post all your systems specs. Total number and type of drives, name of PSU with amperage available on the 12V rail, etc.

 

[darkguset]

OMFG Did you f*king connect the extra f*king molex on the damned card?
LOL!

 

[erocker]

Is this true?!?!

 

[4745454b]

Is what true? People asking questions without enough details? I can assure you 100% that this is very true!

 

[4745454b]

To the OP, and anyone whos wondered why a PSU matters, this is why you need a good PSU. First, read this link. Notice under System Requirements, it says that you need

425W PCI Express-compliant system power supply with a combined 12V current rating of 28A or more

Now what if you have this PSU? Its a "large" 630W "beast", which is more then the 425W thats needed right? The total wattage is enough, but this one fails to provide enough power on the 12V rail. It can only provide 26A on the 12V rail. In terms of 12V wattage, the 8800GTS needs (12V * 28A) 336W, while this 630W PSU can only provide (12V * 26A) 312W.

Whats worse is trying to get a PSU like this one to power the card. It would force the PSU to run at its max power output, resulting in large amounts of heat. This will shorten the life of the PSU, and possibly cause it to die with dramatic effects. To the OP, if your PSU can't put out 28A on the 12V rail, there is a good chance that this is the cause of your problems.

OP look at the psu reference list linked in my sig and find a psu with 30A+ on the combined 12V rails. Stickies are there for a reason, PLEASE READ THEM!

 

[xoulu]

Hmm I will read my power supply info and post it up soon

 

[monst0r]

ahh.. didnt even think of psu as the problem. usually you would check the amps, watts, etc. before purchasing the card to see if it would run ok. lesson learned today i suppose for OP.

 

[tdank]

Check your AA and AF settings in the NVIDIA control panel. Found out I had the application controlled as well as the hardware controlled running. Doubling them up like that sucks the life outa any card.

 

[tdank]

Double post :?
