If glxinfo says OpenGL 2.0 is supported, it does not necessarily mean that it's supported in hardware. > Definitely, any time I attempt to do anything that might be vaguely > OpenGL related (fades, dissolves, etc), their is a CPU spike and 60+ > percent drop in frame rate. Almost all OpenGL accelerations use shader programs, and I don't think that a FX 5700 has shaders. Dissolve is one of the few that do not use a shader program, but it uses some sort of texture-to-texture rendering, which may be a feature that only newer hardware supports, so your driver falls back to software rendering. -- Hannes _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
