Shaders missing on my WindowsXP & ATI - Richard - 10-03-2008

I use the vdrift-setup-2008-08-05.exe but the game doesn't show the shaders on my machine, so most of the polygons look very dull and I'd be keen to see graphics like the screenshots show.

The stderr.txt reads :

Quote:Card supports: drawbuf4 auxbuf0 antialiasing anisotropy16 cubemapping shaders multitexturing16(8) texture_rectangle depth_texture shadow framebuffer_objects
Card does not support:

[Sound etc]

It's Windows XP pro on a DELL Vostro Slim Case with ATI Radeon X1300 pro 256 MB, recent drivers.
On the same machine other OpenGL applications run fine with shaders, for example Sauerbraten (Cube II). Also Blender runs fine (not sure if it uses shaders, though). I think the OpenGL drivers work fine.

What could cause this problem?
Thanks for any help and hints.

All the best and thanks for this great game!

Unfortunately I'm not printing out enough info to determine the problem. Do you know much about the glsl language? One option is to look at the full/fragment.glsl file and comment stuff out selectively until it compiles to try to find the problem. Another option is for me to put in more debugging info and then have you try to compile from source. Or you can wait until the next release... I bought an AMD/ATI card so I can test with that now before releasing.

Hi Joe, and thanks for your fast reply!

Unfortunately not. I just know it's a C like language being used to make the graphics card calculate effects per vertex/pixel.

Quote:One option is to look at the full/fragment.glsl file and comment stuff out selectively until it compiles to try to find the problem.

I'm going to give this a try. However I don't know glsl and shaders in general. Is it possible to print out (hehe) some debug info with the full/fragment.glsl ? I suppose not.

Quote:Another option is for me to put in more debugging info and then have you try to compile from source.

Debugging info would be helpful, but unfortunately I've never compiled a C/C++ programm on my machine before... :-| I could help out with Java, though. :-)

That's good.

I've found the helpful Windoze tool GLview (M$ .Net) which prints out what the various graphic cards support (you can select not only your own card but also many others). For my ATI X1300 card (with ATI driver version 6.14.10.4396) it prints out:

However, I'm not sure if this is helpful in any way what's concerning the shader problem...

Okay, I fiddled around with the shaders on my ATI-powered computer and made some changes to get them to compile. You can download the updated data/shaders/full/*.glsl files here:

http://vdrift.svn.sourceforge.net/viewvc/vdrift/vdrift-data/shaders/full/

With my 4850HD I get 100-200 FPS running at 1280x1024 and everything set to the highest settings. I'm not sure how well your card will perform, let me know.

Note that motion blur doesn't work correctly so keep that turned off. Keep shadows turned on, otherwise it will select a different shader that I haven't fixed yet. You can fiddle with the other settings to get a playable framerate (hopefully).

Hi Joe and thanks for your help!

The good news:
Now the shader's reflection effects are there and look great!

The not-so-good news:
My ingame frame rate dropped from ~ 50-60 fps to ~ 10 fps... (in the menu it's about 60-70 fps.) This I don't understand...
When I restore the fragment.glsl with the old version which produces errors, the fps increase again to ~ 50-60 fps (because shaders aren't wortking then, I suppose).

This is all with 1280x1024 and everything set to highest settings.
Setting the options to lowest did just bring a 2-3 fps increase. So I guess it's something to do with the shaders.

- joevenzon - 10-09-2008

Doh, I was afraid of that. I read up on the X1300 a bit and although it's a somewhat recent card it looks like it's a low-midrange model. Make sure you turn off Anti-aliasing and maybe try a lower resolution. Other than that, the only other option is to turn off shadows -- see if that keeps the cars shiny (so, the no-shadow shaders compile fine), or if it ends up disabling shaders and making everything look flat (the no-shadow shaders fail to compile).

- joevenzon - 10-09-2008

By the way, for comparison my nvidia 7600 GS would get about 25 FPS with all settings set to high at 1024x768 on Paul Ricard w/ the TL2 car. My 7900 GT gets 32, same settings & track. It's pretty dependent on the track. The main slowdown is the shadowing. I'll try to be more generous with shadow detail settings in future releases.

Indeed; it's one of those being inside DELL's new (=2007) Vostro. With 256 MB V-RAM I thought I'd be OK, but you're right, it's just :

Quote:it looks like it's a low-midrange model.

Unfortunately.

Quote:Make sure you turn off Anti-aliasing and maybe try a lower resolution. Other than that, the only other option is to turn off shadows -- see if that keeps the cars shiny (so, the no-shadow shaders compile fine),

Disabling Anti-aliasing and shadows improved a lot: jumps from ~10-12 fps to 25-35 fps, with the cars all shiny. So I can play the game again.
All the other settings I kept to maxium, because lowering the option values didn't bring a single frame increase.

Thanks again for your help.

Excellent, I'm glad you found some settings that work for you.
