Smile New GPU recomendations

I am looking at replacing my nvidia gts 250 with one that has better support in OpenBSD (2d/3d accel). I have looked into the ati x850. Can anyone else give me recomendations? First hand experiance with a card would be good.

$ dmesg | grep ATI

$ glxinfo | grep direct

$ xdpyinfo | grep -A1 screen
default screen number: 0

screen #0:
dimensions: 3360x1050 pixels (886x277 millimeters)

$ glxgears
1725 frames in 5.0 seconds = 344.995 FPS
1732 frames in 5.0 seconds = 346.244 FPS
1730 frames in 5.0 seconds = 345.855 FPS
1730 frames in 5.0 seconds = 345.222 FPS
1728 frames in 5.0 seconds = 345.492 FPS
Dual 22" widescreen LCD's. Works like a charm, though I had to put "xrandr --output DVI-I_1/digital --right-of DVI-I_2/digital" in .xinitrc to get dual screen (i.e. no mirroring) working.

That actually no longer indicates that DRI is working, AIGLX seems seems to set that field to "Yes" even if the software rasterizer is loaded.

Use glxinfo | grep renderer instead, I'm guessing that you're actually not using DRI.. as ~344 FPS is rather slow, my ancient Radeon 9200 SE (..r200) gets over 900 FPS with glxgears.

On OpenBSD, for good 2D/3D.. R200/R300-based radeon GPU's are the best supported ATI cards, no DRI module is built for r500+ cards.

Well that's retarded.

And yes, that seems to be the case. Thanks for pointing that out.

Thanks Guys. I'm going to look at r200/r300 chips. Unless anyone can suggest better I will go with a ATI Radeon X600. Would a dual link like this work with OpenBSD. ATI Radeon X600

It has nothing to do with AIGLX. In fact, if you set the LIBGL_ALWAYS_INDIRECT variable, forcing apps to use AIGLX, you will not get direct rendering.

It's simply that the software rasterizer included in Mesa these days supports direct rendering. If you disable AIGLX entirely in Xorg, but still use software rendering via Mesa, you still get direct rendering.

Just to update for anyone looking for a gpu. Everything seems to work on the x600 xt. Good card, cheap and passive. Win all around.
