CPUID and Power Strip say AGP n/a but...

[bixster]

I have a 32 meg G400 DH running PD 5.52 on a Soyo 7VCA. It's never run reliably past 1X, and in the past few days Power Strip, Sandra and CPUID report that AGP is somehow disabled.

I bumped up the clock 10% in MGA Tweak and it _greatly_ improved my Wintune numbers, although AGP is supposedly disabled.

Here are my Wintune results:

Now they seem fairly decent to me. Before I twiddled with MGA Tweak, the 2D performance was about 10 MPixels less.... but the Direct 3D score was at 44 and the Open GL was a paltry 15. How did tweaking the clock 25 ticks cause such a huge performance increase to 338 and 158? I'm new to MGA Tweak. Is this a normal performance increase? Regardless, it has made my new machine noticably snappy, so I'm not complaining.

Should I disregard the AGP n/a messages? Is there a reason AGP would/could be really disabled? Thanks for any input on this...

Hi Bixster,

don't know what could be wrong with your system, but I suggest to run 3D Mark 2000's 64MB texture rendering tests ...

If you get a slide-show, there's no AGP transfer, but if it's around 100fps, just ignore those false reportings ...

Besides that your Wintune results are pretty impressive.



Cheers,
Maggi

Well, right after I posted those numbers, I did something that caused my performance to revert to its old scores... showing much more modest gains using the same MGA Teak settings...

I installed the 4.03 Via AGP driver as well as the 6.0 beta Matrox drivers, and now I've got 2X going. Much better 2D scores, but my Direct 3D/Open GL scores are still pretty bad:

I don't know what I did before to somehow boost my 3D performance 10-15X, but I can't replicate it. Anyone have any tips on getting those numbers up? Since I don't play many graphics intensive games it's not that big a deal, but I still feel I should be able to improve those 3D scores.

1152x864@24bits/pixel

... in 24bpp hardware acceleration is disabled !!!

Set to 32bpp for true color and 16bpp for high color to re-enable hardware acceleration ...

Well shucks... how come I didn't know that? Changed the rez on my P3V4X to 16 bit and my numbers took off. Now to try it on my 7VCA. Many thanks....
