Radeon 9200 and AGP Express

Somewho · 03-28-2012, 09:25 AM

Thanks for useful info. I've read about "AGP Express", but haven't read about 845GV.

So reporting "forcing AGP to PCI mode" would be correct. Its not actually a AGP slot, its a PCI slot that looks like an AGP slot.

Yes, I know.

Splinter cell might be running from the video RAM and only needs to put new stuff into video RAM when changing stages, etc..

And works faster that glxgears?

I can't believe.

I've downloaded GPU-Z for Windows (attachment). Yes, assuming my current knowledge about 845GV and "AGP Express", looks like under Windows all works as it should. But not under linux

By the way, in my lspci's output for Radeon I've found

Quote:

latency 32

. Is it OK?

UPD
I've manually set it's latency to 0, but nothing changed.

I dont get what you are trying to say here.

GLXgears in not a benchmark anyway.

Your GPU-Z sceenie shows that you are using PCI mode with windows as well (Bus Interface AGP 2x @ PCI).

Latency 32 is fine AFAIK.

I mean, even if that game is using some optimization, I can't believe that that is the only reason why it works faster than simple 3d-test (or what glxgears is). I hope, now you understand me.

Yes, I've understood GPU-Z output before posting

That was just a proof of your post about lack of AGP 4x at 845GV chipset, and about "AGP Express" meaning.
I've tried to manually set

Code:

        Option "BusType" "PCI"
        Option "AGPMode" "2" # I thought, may be, Xorg is trying to work at 4x speed and fails

in xorg.conf, but, as always, no results.

Yeah, now I've got it, thanks.
