The card has 32MB RAM and I'm usually running at 1600x1200x24.... is this reasonable?
It seems the Radeon driver doesn't have the fallbacks you mention, then?
Of that 32MB, almost 23MB are taken up by your framebuffer and depthbuffer. That doesn't leave a lot of room for textures. You should try increasing your GART memory to 32MB or 64MB. Add a line like:
Option "GARTSize" "64M"
to your device section.
It seems that the M shouldn't be there. ANyway, I did this, but it doesn't help at all. Look at these snippets:
(**) RADEON(0): Option "AGPMode" "4" (**) RADEON(0): Option "GARTSize" "64" (--) RADEON(0): Chipset: "ATI Radeon QD (AGP)" (ChipID = 0x5144) (II) RADEON(0): AGP card detected (**) RADEON(0): Using AGP 4x mode (II) RADEON(0): AGP Fast Write disabled by default (II) RADEON(0): Depth moves disabled by default (II) RADEON(0): Page flipping disabled (II) RADEON(0): Using 8 MB GART aperture (II) RADEON(0): Using 1 MB for the ring buffer (II) RADEON(0): Using 2 MB for vertex/indirect buffers (II) RADEON(0): Using 5 MB for GART textures (II) RADEON(0): Largest offscreen area available: 1600 x 4040 (II) RADEON(0): Will use back buffer at offset 0xeaa000 (II) RADEON(0): Will use depth buffer at offset 0x15fd000 (II) RADEON(0): Will use 2752 kb for textures at offset 0x1d50000
So:
1) although the optoin is recognized, it still only uses 8 MB GART aperture (note that my BIOS is set to 64 MB AGP Aperture). Still only 5MB for GART textures.... :(
and, some other questions"
2) AGP Fast Write is disabled. Is it smart to enable it? It is enabled in my BIOS, by the way.
3) Page flipping is disabled. Is that good?
Can we make the driver use a larger GART size by default when DRI is enabled? 5MB is just about worthless. I would suggest 16MB as a bare minimum.
What can I do now?
Kind regards,
Manuel
