Geforce 2 GTS- Problems w/ framerates

[Mezzanine]

Hi'

I've been having problems with the framerates when I run games like UT (or anything for that matter) on my GF2 GTS. It seems that whatever I try, the framerates drop TREMENDOUSLY when more polygons get on screen. Now I know it's normal for them to drop, but these framerate drops are abnormal. In Unreal Tournament, it can go from as high as 160+ FPS to below 28. Its really odd, here are my system specs:

-TBird 1.1ghz
-128mb Ram
-GeForce 2 GTS 32mb DDR
-DX8
-Win 98

I have tried all the following to attempt to fix this problem:

-I started w/ Windows ME, then went back to 98 and the problem persisted
-Reformatting my drive
-Using DX7 instead of 8
-Installing the VIA 4 in 1 drivers
-Installing almost ALL detonator drivers
-Checked to make sure my GF2 isn't conflicting w/ any other devices of sharing IRQs
-Turning off individual GF features (like FSAA, etc)

So, as you can tell, I've tried mostly everything. If anyone can help at all, it would be appreciated. Thanks in advance.

Try different settings for your agp apeture in the bios.

I tried changing the AGP Apeture in my BIOS settings. Still no use. Any other suggestions? They would be greatly appreciated.

Maybe you can find something at one of these sites.

Well, unfortunately those sites had no help for me (well a little but not much). Any more suggestions would be greatly appreciated. Thanks.

I wish I had that problem rather than my own. I've got a Leadtek Geforce2 GTS/Pro mated with an Athlon 1.2, and I get 60 frames per second in Quake ONE. About 30 FPS in halflife, and around 50-60 in UT. I've been trying everything, different bios and drivers for the motherboard, DX versions, vid board drivers, nothing will help.

So anyone else have suggestions? I'm depserate here . Some games, like Black and White, are just too hard to play because of the high polygon counts (which I think is the problem with my slowdown). It should not be this slow, I know this for a fact. This is very odd, as my friend on a Pentium 3 w/ GeForce 2 GTS Pro gets smother fps with an 800 mhz machine.
