well
amd 3000+ 2ghz no o/c
1 gig ram
ati 9800pro no o/c
Ah Setup 1024 tex at 1024x768 with hi res pack
in h2h i get 90+ FPS in SE i get 195 and in MA i get 30s-60s
plus i want to have full detail range. Is there any way?:confused: more also have 6aa on

Run Aquamark and see what you pull as a benchmark. That will give you a start point. To improve you'll need to either optimize your system (what % of system resources are being used at start up etc)...optimize your drivers...overclock....or all three.
You can also look at your ram...what are you running and how good is it. To me with your AA at x6 your pulling very good framerate.

Go down to 512 on your textures and knock you AA down to x4 (my best guess).
Here is a copy of Skuzzy's Video Memory optimization formula. I tried it. Was getting ok frame rates, but would get drops and hesitations I couldnt figure out. Skuzzy set me straight, and I have had really good frame rates and stable video ever since.
At the time I was running 1024x768 resolution, 1024 max textures, 4x AA. If your number you come up with is higher than the amount of video memory you have, you will be swapping in and out of memory, which eats up the card's resources. You make the card work harder, you get drops in frame rates and stutters under a load. You can see by the results, if I had a video card with 256MB of RAM I would have been fine. My card only has 128MB. I had to adjust my settings. I havent regretted it since.
Here is a simple formula Star. It is about the amount of video ram needed for any given frame. This is an approximation.
Drawn_Frame_Buffer = (Horizontal Resolution * Vertical Resolution) * 4;
Working_Frame_Buffers = Drawn_Frame_Buffer * 2;
Total_Frame_Buffer_Space = Drawn_Frame_Buffer + (Drawn_Frame_Buffer * AA level);
Aces_High_Texture_Space = (Maximum Texture Size / 5) * 1MB
----
Now, add it all up.
Approximate Video Memory Required = Total_Frame_Buffer_Space + Aces_High_Texture_Space;
(1024 * 768) * 4 = 3.07MB;
3.07MB * 2 = 6.14MB;
3.07MB + (3.07MB * 4) = 15.35MB
(1024 / 5) * 1MB = 204.8MB
220.15MB
Now this is a rough estimate, but it gives you an idea of the amount of video ram needed for any given scenario.
This also does not take into account the amount of scratch pad video ram required by the video card and drivers. You can toss in another 4 to 8MB for that, depending on the video card.
In a best case scenario, you want that total number to be less than the total amount of video ram you have available.

you do know having vsync off is not good for AH?
you are nto getting anything close to those FR in reality, no moniter runs at 195hz
-
What JB73 said. You should have Vsync on to see what your frame rates really are.
-
ha is on don't even know where its at :p with anim water on
-
monitor gos 2 180

Ok here u go 30237

Now you have an initial bench mark....I'd check to see if you have latest drivers...also look thru here for threads on optimizing OS by getting rid of useless overhead. Start with that and see if you can bump it up.
