DOOM3+BFG 6800GT stutters, format??

[SnOop005]

I had a GF4 Ti 4400 card with 61.77 drivers, the first drivers for this card is probably a 56.xx drivers prior to the 61.77. I picked up a BFG 6800GT today. Went home took out the gf4, poped in the GT and let windows find the drivers. Turned on anisotropic optimization, turned off Vsync and ran DOOM3.....omg it stutters like crazy. My hard drive light was on like a xmas tree. I played around in the game for 3-6 min, stutters. Uninstall nvidia drivers, restarted and install 61.77 drivers again. Messed with settings and ran doom3 again. Better but still stutters. Is there anything that i should be aware of? Im just wondering before i waste my time formatting. I was onlying running doom3 at 1280x1024 and 4x AA on Ultra quality.

heres my specs:

Abit IC7 max3
P4 3.4
512mb 3700 Dual channel DDR
7200 rpm hd
Geforce 6800 GT factory clock.

bios settings, 256mb for agp arpature size.

Oh yea i jus ran CS, runs fine tho.

i get the same thing, but only when i run the timedemo, and only the first time. once it finishes and i run it again it's smooth. have you tried defragging your hard-drive for starters?

More ram maybe? Just a suggestion but see if you can borrow a stick from a buddy.

any more input on this matter?

Thats your problem right there. Ultra quality uses uncompressed textures which can be up to 500MB of graphics memory. Heck, your system memory isn't much more than that, and obviously the 6800GT doesn't have 512mb of memory. Because Ultra quality texture's takes up more space than whats on your videocard, it stores some of it on the system memory, and even then, you really don't have much to begin with. The stutters/freezes is the game trying to send the texture from the memory to the videocard, but because your system memory probally can't even hold the full amount, its probally extracting it from your HD too... VERY VERY SLOW.

Turn it down to High, and try again.

Yea, after reading the hardcorp i noticed about the ultra quality so i turned it down a notch...same thing.
How can ppo with similar set up run at 1600x1200 ultra quality with 60-70 fps?

I was having a similar problem...mainly when encountering a "warping" effect (glass, heat, etc.). Nothing I did solved the problem. I ended up doing about 5 things at once, and now it works fine, so I can't say for sure what it was, but by any chance are you running the duct tape mod? I was, and now I'm not and it's not doing that anymore, so I think that it may have had something to do with it. I also disabled my secondary monitor. Some things to try.

Which 5 things did you did, and what's that duct tape mod that you did?

whats a good program that completely remove the forceware drivers?

Thanks

Ultra quality is too much and drop AA from 4x to 2x.

try turning OFF fastwrites.

Ok, Everything is fine now i think.
I end up installing windows on a spare hard drive and test it there instead of jus formating my main drive.

I got 69 fps in timedemo1

1280x1024 on good quality. I compared it to the benchmarks on anandtech guide and it seems fine.

AA and AF are set to Application control and I turned AA off in doom3.

This is running off from driver 61.77

I jumped from a Geforce 4 Ti please let me know if this is within normal bounderies of my set up.
