I tried the FEAR benchmark with everything on high with soft shadows at 1280x960 and my lowest FPS was 27, with an average of about 40. (max 119) (THIS IS BARELY BETTER THAN MY 7800)

I tried the same thing at 1024x768 and my lowest was 43 and my average was 95. (max 190)

Why is there such a huge difference? I thought the 8800 was built to play at higher resolutions.

I've noticed the same trend with Oblivion, its at times almost unplayable at 1280x1024 but at 1024x768 it is as fast as can be.

amd x2 4200 oc'd to 2.5Ghz
2GB Corsair 450 ddr
8800GTS 650/2000
SATA Raid HD
KN8-SLI
8759 3dmark 06

These all at 1280x1024 with additional 16xaa 16x af
15-20FPS Froggy
27-35FPS Adrianne
100FPS smoke
100+FPS BF2

Hmm, od

look here. This is my first tries when i bought my card. http://www.nvnews.net/vbulletin/showthread.php?t=79612&highlight=nowaydude

I wonder if your CPU is slowing you down? I notice a small boost OCing my 4600x2 to 2700 (270x10 in bios)

Are your FEAR Scores with 16xAA/16xAF? If so then thats ALOT better then a 7800 Card considering it couldn't play the game remotly that smooth with 4xAA.

No 16aa,16af were off

as a matter of fact when I turn them on I get nearly the same frame rates as with them off

Sounds to me like your CPU is the bottleneck. Just about every review I have read states that you shouldnt think of upgrading to a 8800GTX unless you have a pretty heafty system (Core 2 Duo/FX). The largest gains will be seen only with top of the line CPU's otherwise it will be the CPU that bottlenecks you.

I just installed the dual core optimizer and restarted the computer now I get 91fps average with max 190 at 1280x1024.


Well that wasn't true--v

As a follow up I enabled supersampling, and forced 16xaa, 16af & soft shadows at 1280x1024 and I got

min: 28
average: 51
maximum: 125

That sounds better. I can play FEAR without a hitch at 1600x1200, 16xAA, 16xAF, and all in game options maxed (SS disabled) and it seldom dips below 30 (I have two 8800GTSs powered by a s754 3400).

So, yeah, even with as huge a bottleneck that my CPU is your framerates should have been a lot higher. I guess that dual-core optimizer really does help. ;)

Well I don't think it was the optimizer that helps, my problem has returned. It seems after 5 minutes of playing Oblivion the frame rate gets cut in half or more. Any ideas?

(I tested the same areas of the game, the first time it was 35-40, after the slowdown the same area was 10-15)

I just ran FEAR again though and I got the same good results.

add /usepmtimer to your boot.ini, see if that does anything
as for the oblivion inconsistency....the weather might have something to do with it?

Hm... Not sure what could be up. I don't own a copy of Oblivion so I can't help much here. Though I know the card should perform better than what you're seeing.

Good luck!

PROBLEM SOLVED!

This is like a major thing that everyone should know. After much fiddling I have found that you must turn OFF transparency antialiasing and you will DOUBLE your oblivion performance even if you have 16x AA / 16x AF enabled.

Before and after I got 13fps and 35fps

I guess all those leaves are transparent and are double antialiased when that setting is on and it drags performance Way down.

Heh, transparency AA is a definite frame-killer. I never use it, honestly.

Well, but especially Transp. AA makes the biggest difference especially in Oblivion...

There's a reason for the performance drop, you know. If there weren't any transp. textures there would be no performance drop. So I'd rather reduce the AA level to 4x or 8x (CSAA) and live with the performance drop. AA alone doesn't make much sense in Oblivion if you disable TSAA... since most of the scene wont get any AA at all.
