I can find just as many benchmarks with the 9800 outperforing the 5900.

The reality is that both cards are fairly even.....at the moment.But with DirectX 9 optimised games being released in the coming year,the 5900 will fall behind.

The xt is a bit fster and newer drivers are available for both cards. Which card is best for you depends on what games you play. Prices are also very close, xt is a bit higher, For AH2 I beleve the 5900 will always be faster, but that remains to be seen.

Where the ATI cards shine is in there FAA thats where they leave nvidia in the dust.
Turn all the eye candy on then see what happends LOL.

sad thing is the 5900 is nolonger the topend card for nvidia.

doesnt change the fact I cant afford anything on that list.

Just FYI: Those benchmark numbers are all worthless.

Doom3 is not released and those numbers are based on some old Alpha of Doom3, which is not relevant, and NVidia disables tri-linear filtering when running UT2003 to improve its scores.

The Cat 3.10s are scheduled to be released tommorow. (Wednesday) They look to be primarily a bugfix release.

The 3.10s are out. I haven't tried them yet, but will this evening.

Man I would love to know how you guys are gettin such frame rates...do you have all the "eyecandy" turned on on your cards such as anisotropic filtering and anti aliasing?

I am running 2.0 Ghz machine, 256 megs ram, ATI Radeon 9800XT with 256 megs ram on it.

Frame rates are stinky at best...choppy and rates from teens to 40 or so.....mostly choppy and in the low end. I have the eyecandy turned up on my card and overclocked it. Also have the screen set at 1600x1200 and the next one down...NO MEASURABLE DIFF.

Any suggestions????

TG12:confused:

Since I had to uninstall my ATI drivers anyway, I figured I run a test:

There's most definately something not right with the Radeon 9500 and up cards in AH2. My GeForce 4 Ti 4200 (put it back in for a test - 41.09 drivers) delivers over 2x the framerate of my Radeon 9800 (standard 128 MB, NOT SE or Pro/XT) in 1.997 at 1280x1024 32bpp (no FSAA or Aniso).

The new Cat 3.10s do not seem to be any better than the 3.7s for AH2. I haven't yet tried them in anything other than AH2, so I don't know if OpenGl is still broken, as I found with the 3.9s.

A couple things I've noticed, between the nVidia and Radeon cards, in AH2 1.997 is that on the Radeon cards there is a very noticible stutter that occurs at a very regular interval (offline at least) of about 1 second. This started with 1.995 for me.

1.995 and up are nearly unplayable with all the detail sliders in AH2 to the max (25 fps on the runway, dropping as low as 17 fps in flight - 1280x1024 32bpp). At about 80% the framerate is acceptable at about 39 - 45 fps. The triangle count drops from well over 20000 to about 12000. Strangely enough, turning on 4x FSAA has no significant impact on framerate, 2x has none at all. (On the GeForce 4 TI 4200 you couldn't turn on 4x FSAA and get even 25 fps in AH 2, and there was a very large performance hit enabling it.) This would lead me to assume that this isn't a memory bandwidth/fillrate issue with the Radeon card, but rather something else. It might be a driver issue, or it might be something to do with AH2, it's really impossible to tell for sure. Considering that in every other game I have the Radeon 9800 is significantly faster than the GeForce 4 Ti 4200 I think it might be something to do with AH2. AH1 runs at my monitor's refresh rate (85Hz - 85 fps) with 4x FSAA turned on at 1280x1024 32bpp under nearly all circumstances. The first beta version ran MUCH faster on the Radeon card and performance has been dropping slightly in future releases. (I got 75 - 85 fps down low with 4x FSAA on in 1.9901 for example.) 1.995 was the big hit though.

I sure hope HT can track this one down.

Detailed hardware specs:

Athlon XP 2400+ @ 2.13 GHz (2600+ effectively)
Asus A7N266-C bios 1.05 b2, newest nVidia chipset drivers
Radeon 9800 128MB standard, cat 3.10 (was using 3.7 previously)
4x AGP rate, Fastwrites enabled (made no real difference either way)
Direct X 9.0b
512 MB DDR
120 GB WD SE HDD
nVidia Soundstorm audio (ob)
Windows 2000 SP4 + all critical updates

That's very odd. In AH my FPS are pegged at 120 it never drops except for a click to 119 then back to 120.(my refresh rate is 120)

In AH2 I'm in the 70's all the time, drops to the 50's on occasion.

Both of these are with all the eyecandy turned up and vid card settings on max quality.

Spec's

P4 3.0
Gigabyte K8NXP
1 GB OCZ DDR400
ATI 9800XT
Raptor 10k SATA in RAID 0

I have an FX 5600 256 DDR

AH2 only shows 130.4 M of video mem yet AH1 shows the full 256+.

Off course it does not show its using it all either........ it just seems strange.

FPS's seem to vary widely with settings both within AH2 video settings ranges and within NVidea control panel settings ranges.

Just trying to gather more information. What AGP Aperature size are all you running at?

mrblack · « **Reply #28 on:** December 18, 2003, 04:33:29 PM »

If your asking about that setting in bios skuzzy mine is at 128.

If it's the one in the vid cards settings then its agp x8

Fast writes off

JustJim · « **Reply #29 on:** December 18, 2003, 04:57:43 PM »

AGP 4x

AGP Aperature size 256
