Sauerbraten, FC5, Radeon 9200: streaky vertical textures

Hi,

I've got Sauerbraten 20060611 on a Fedora Core 5 notebook with a 64 MiB ATI Mobility Radeon 9200, using the standard radeon driver that comes with X.org. Textures on horizontal planes show up OK, but on verticals they seem to streak out --- see the URL below for an example.

Is this "normal"? Can it be corrected?

Thanks,
James

That\\\'s odd i get 190 FPS and it looks fine on my 9250 256mb. have you tried updating your Catalyst?

Yes, definently try new drivers.

I find fglrx is currently broken for the 9200 under FC5 (libGL binding errors)... I\'ll try again later and see if they fix anything. (I remember both Cube and Sauerbraten being completely FUBAR with fglrx in the past and stopped using it.)

I see the vertical streaks in the Mac OS X build running on a Geforce3 - I doubt it's an ATI problem!

Well guys, I did *try* updating fglrx, but I've got a 9200 chip (specifically, RV280) and ATI have gone and broken the current release on it... Additional info: verticals are OK on Cube.

Do you have shaders turned on? That happened to me, until I realized I didn't have them turned on...

Don't think I have got shaders (see debug output below). Is there any way to force them on>

Yes - buy a new video card.

The texture streaking bug was fixed by adding the shader system. If you have to disable the shaders for fps, or if your video card doesn't support the shaders ( a 9200 does not support them btw ), then you are running sauer with the older texture rendering methods. Even certain nvidia cards have the texture streaking problem under the non-shader conditions. If your video card does this, you have no way of stopping it.

There is the slim chance that certain drivers might fix it, but thats hit-and-miss from different video cards...ati, or nvidia.

Better get out the soldering iron then... this is a notebook ;)

Well, then forget running Sauerbraten on it. Thats the main reason I will not buy a notebook...I'm a gamer, and I would have to throw it away after it was a year old.

I'll stick to my tower case pc, where I can toss a couple hundred dollars at it once a year and stay up with things.

I've just tried Sauerbraten on my Intel 855-based notebook, and the thing renders fine (but runs dog slow). This must be an X.org/radeon issue; I'll try things it on Windows later.

It´s a driver issue. Try updating your drivers/using diffrent ones.

In the first screenshot it looks like you are using vista :/


That could be a problem, but maybe you just have a theme.

Mesa? It is a software implementation of OpenGL! That explains why it is so damn slow!

Use the original x.org-radeon drivers, not the fglrx drivers
