Low FPS with 8800GTS

In BF2 I am getting low FPS. My card is even Overclocked to 625 MHZ and 1000mhz ram. It will frequently hit 30fps and averages probably about 50. On my old X1950XT it would average about 75FPS. It would almost never drop below it if and when it did it would only go as low as 65. I am using forceware drivers 158.22 and have it set to use application settings.

Also to make sure it wasn't doing just bad in BF2 I did the Half life Lost Cost stress test and it averages 44FPS. That is completely horrible. When I had my proc at just 3GHZ and a X850XT installed I played the whole Half Life 2 game with an average over 60FPS.

Ive had a X850XT, X1950XT, and now 8800GTS. The 8800GTS is 3 generations ahead but is worse than the X850XT. What's wrong. I might reinstall windows soon hopefully it will fix this unless you have better suggestions.

1.) Could be ur PSU not having enuf pwr, but more likely...
2.) Drivers... try one of those 'driver unilstall' apps thats abt all i can think of rly

I have a combined total of 36amp on both rails max and 20 amp for a single rail. Also PSU calculator calculates this system to be 513watts. When I had the X1950XT it calculated it out to about 600 watts so it should actually be better off now.

I tried CCleaner to uninstall drivers but it didn't help.

The game is at the latest version. BF2 is not the only game experiencing the problem.

if i was you i would bum a better psu off a friend to test it and see what happens

what you will find is that the 20 amp rail is powering the cpu while the 16 amp rail is powering the hdds , mobo ,gfx ect
June 14, 2007 6:39:36 AM

The CPU is only taking 124 watts so 124/12 is 10 amps. The 8800GTS over clocked to about what I have it at is 120 watts to 120/12= 10 amps again. The 3 HD's that I have take a max of 13watts each so 39watts all together /12= 3.25 amps. A high end Mobo takes on average about 50watts/12= 4.2 amps (This isn't even a high end Mobo). My system is only taking about 28 amps from the 12v rail when everything is working as hard as possible. I have 8 amps left, the PSU is not a problem.

maybe its just a bad card? have you tried popping it into someone else's rig and seeing what happens to your fps?
June 14, 2007 6:54:50 AM

Ya i can pop it into another rig but that rig probably will have a PSU problem as it only delivers 18amp on the 12V rail. Plus Ill have to deal with drivers. I might try to do that tomorrow if all else fails.

well dont try it in an underpowered rig or else you'll def fry it. find a nice rig with atleast a moderate power supply and see what happens.

yeah but what have to remember is that there are 2 rails not one so if the cpu is on one rail ( normally the 20 amp ) so you only have 16 amps for the gfx (10 amps) , hdds (3 amps) , mobo 4 (amps) = 17 amps which is over 16 amps
June 15, 2007 3:53:44 AM

Both rails can put out a max of 20 amps. Why would it give 20 amps to something that does not use it all? It doesn't it will dedicate it the way that requires the most power. I have 3 amps left for all that stuff. And I think the Mobo uses the same rail as the CPU draws from (not sure).

I reinstalled windows today it helped a little but it still will hit 50fps occasionally. I'll put a X1950XT into it again when I have time and see what it gets. The X1950XT guzzles more power than a 8800GTS too.

I don't know anyone with a nice rig all my friends have everyday average dells.

im running 8800gts 640- I'm not home to look now but I remember that evga recommended a 20+ (26maybe) amp 12v rai; for this card. hit evga even if it's not an evga card most of whats out fits.
good luck
June 15, 2007 5:01:57 AM

one other thing- make sure this card sits on the rail alone if you can.

any good news Derek? I've got the same issues with my 8800GTS 640, and its not o/c. Its at stock clock speeds, 513Mhz core, and 792Mhz mem. I'm avg around 59-75 FPS on BF2, all max settings. Even when I tried it at lower settings, I got the same FPS. I've already updated all the drivers; and uninstalled/reinstalled twice.

FYI:
For Lost Coast, I was able to avg out at 68.12 FPS with normal clocks,
and 68.45 FPS with 620 Mhz Core/ 1070.Mhz Mem. Any ideas, as to why the low numbers even with overclocking?

Its not your psu i can tell you that. Unless it is going south on you.

I have the same psu and gpu plus i have used sli in the past with no problems.

In bf2 and a single card i am at 100fps constant.
this is with a x24400 and a 16x10 monitor.

I solved the problem a complete reinstall of XP worked. My guess that I didn't completely get rid of the ATI drivers. Now I get 100FPS and 80 in the most intense battle scenes.
June 26, 2007 5:31:32 AM

so needless to say, i should do the same thing?
June 26, 2007 5:33:57 AM

I think it should definitely help.

I never get this problem, but then an XP install doesn't last longer than three months on my rig anyway. [/extreme madman]

Meh. :D  My 420W Sirtec is specced to give 18A to 12V rail. Kinda explains why I really can't overclock my 8800 GTS that much -> gets pretty random while my cpu/gpu cooler gets dusty -> more heat -> uses even more. :p 

Yeaaaah, new PSU + mobo + processor + rams + case coming ...during this year. :p

I'm looking at hacking a secondary PSU to supply my GPU exclusively - 500W is starting to get a little... limiting.

In order to OC my GPU, I have to de-OC my CPU. Fun...
