Help needed again (ATI users only)

[Graf Zahl]

Can someone with a fairly recent ATI card and driver please post the GL extension string that GZDoom outputs on startup?

I fear that a few things I need for handling dynamic lights in a shader require features ATI hasn't implemented yet and I'd like to know that before investing any work there.

Once I can get to my dad's machine with his ATI Raedon 4830 I'll grab the information.

And I was able to get to my dad's machine. Here's the output

[Graf Zahl]

Thanks. And good news. Both of the extensions I need are supported.

[Gez]

Which ones are they? Any of those?

These 2:

GL_ARB_texture_buffer_object/GL_EXT_texture_buffer_object (different name, same functionality)
GL_EXT_gpu_shader4

I need them to handle dynamic lights in shaders. Texture buffers are the only method to get a sufficiently high amount of coordinates to the hardware.

[GuntherDW]

I've checked on my laptop with an HD3650M (Dell studio), using the latest drivers (9.6),
and those 2 show up in glxinfo.

so they are "supported" in linux as well

altough i just compiled the latest svn, and it's a little unstable (all kinds of (debug?) shader linker messages in the console, and a couple of WARNINGs), and quitting crashes the game.
but that's another problem

GL_EXT_gpu_shader4

They exist in my extension string, if that matters.

[Graf Zahl]

Ok. I already checked ATI/AMD's driver specs. Looks like the texture buffer objects were added in Catalyst 9.3.

[Gez]

They don't in mine, if that surprises anybody. And I've just updated to Catalyst 9.3; it added some of the "missing" ones, when comparing to Insanity Bringer's list, but not those ones.

[Graf Zahl]

Maybe your hardware is too weak...
