AGP Option Grayed out on Radeon 9600 4x AGP Card

Hi. I have a Pentium 3 800 MHz with 384 MB RAM. I have an ATI Radeon 9600 with 128MB in 4x AGP mode. However, when I go into advanced graphics in preferences, my option to activate AGP mode is grayed out. I have had SL "autodetect my hardware" after installing the latest ATI driver (released June 9).
Anybody else experience a similar problem? Is there a config file I an override or something?
Thanks very much in advance for any advice.

AGP features are disabled for ATI users. Linden blames ATI.

That's too bad. . .

this game looked like fun! :(
It's really unplayable for me, but I guess 800 MHz is the minimum after all. . .

I have seen a similar thread stating the same thing, but I think I ought to reply to this one since I never did the previous. I get a notification dialog stating that my card is in PCI mode and that AGP mode is disabled. The AGP checkbox is also grayed out for me.

The interesting thing here though is that when I first installed and ran SL on this computer, prior to UPDATING my ATI Radeon Mobility 9200 drivers (at http://www.OmegaDrivers.net), I did not get this warning/notification dialog upon starting SL. So.... I don't know what to make of any of it, really.

I never even get the "PCI mode" dialog. It just silently has the AGP disabled. When you had old drivers, did the AGP mode work? I may be able to revert if necessary.
(gripe) Shouldn't my hardware be transparent to the implementation anyway? I mean, I don't recall there being a DirectX "AGP" mode, although I could be wrong. . . (/gripe)

On second thought. . .

If you have a mobility card, I'm guessing you're using a laptop? Is it possible to have AGP on a laptop?

When I had older drivers, I never payed attention to the checkbox you mentioned. I am still not real sure what it does. (See dialog content below) With the old drivers, I now assume it did not work since I have twice seen that LL disables AGP with ATI cards. But I am absolutely possitive I did not get the pop-up dialog that I now get, which states:


From: SL 1.6.7
GL indicates that the graphic driver on this system is running in PCI mode, a slower method of drawing graphics. If you're using a PCI video card, you can ignore this message. If you are using an AGP video card, you should update your motherboard drivers for improved performance in this and other 3D applications. If you are using a PCI Express graphics card you can enable AGP Graphics Acceleration from the Options panel in Preferences in Second Life.


And yes, I as far as I know, I have AGP capabilities in this system. The utilities that come with the Omega drivers say that it's running at the system max of 4x. Other utilities such as Everest Home Edition also corroborate that I have an AGP bus.

One other strange thing worth mentioning while on related topics: the Omega drivers as well as hacked Catalyst drivers (DH ModTool 2.2) both detect and install my card as a Mobility 9000, rather than a 9200 (what the HP OEM drivers and system specs refer to it as)

The AGP mode for the ATI card is greyed out for all ATI cards. As I understand it, this is just a method SL uses to handle textures and isn't that big a deal as far as performance is concerned. ATI varies from certain standards that SL doesn't like and that is one of them.

Right, Nick, there's three reasons you're getting poor performance in SL: your CPU is slow, you don't have very much memory and given that it's a P3, your memory bandwidth is slow. Your video card is pretty good, but even if you had a video card that could take advantage of the AGP option, SL is still CPU-bound anyway.

Kathmandu's correct, toggling AGP mode on my Nvidia-equipped computer does affect SL slightly, but not as much as it the name might indicate.

Adding more system RAM might make SL more usable for you, but not as much as a new CPU would, and that's a huge hassle, not to mention expensive.

More ram would definetely help. But on the PIII platform I dont think you will make the 1 GB I think you really need to enjoy good system performance. The various PIII chipsets dont support that much. I think some goto 768 though. Overall your best bet is get a new machine. You should be able to move your nice video card over to it. And most manufacturers have machines with decent specs for under 300 now. Just move your video card over and upgrade the ram to 1GB and rock and roll.

Most cases where an AGP video card is running in PCI mode, this indicates that the motherboard "GART" drivers are not installed properly.

YMMV.

Yes - AGP is about the wiring and the data protocol, not the physical plug. There are many, many computers out there with on-board AGP graphics controllers, notebooks as well as desktop PC's.

ATI Cards and AGP Option

Must be only for Windoze user's. My ATI 9800 Pro Mac Special Edition (256) has always permitted the AGP option in Preferences settings.

I am not sure your statement is correct, even for the Windows users.

Can't say if it is correct or not but that is what the Lindens have said repeatedly.

I've got an ATI Radeon 9800 Pro w/256Mb VRAM...when I first joined SL the AGP checkbox was useable but due to some SL updates and ATI driver updates there became an incompatiblility somewhere and so LL has since disabled that feature for ATI cards (and have stated as much somewhere else in the forums, I just can't remember where and am too lazy to look for it to provide a link here...heh). However, I haven't noticed a lick of difference performance wise, everything still runs great and looks as good as it did the first day I started playing when I had the little AGP box checked (can you say placebo? lmao). As some ppl with Nvidia cards have mentioned, they don't notice much difference (if any) with the AGP box checked or not (again, say it with me now, placebo). Also as other ppl have mentioned, a P3?!?!?! yikes, you desperately need to upgrade your system...hit a computer show this weekend and come into the new millennium with the rest of us...lol :p (just teasing, but you seriously should consider upgrading ASAP)

Same here....horrible performance.
02-16-2006 00:51
2.8ghz Intel LGA775
2GB PC3200 RAM
256 MB 8x ATI 9600 AGP card.

AGP option grayed out.

Everquest 2, Planetside, Auto-Assault...ALL run with amazing performance at balanced settings.

Second life, if I turn everything down ALL the way, I am lucky to get 15 FPS.

Horrible...=/

(yes - i have good drivers, and all updated windows XP junks)
