And it has to be the same pixel format if it's the same (wide) buffer. :-) > > BTW, the 8800 is limited to 2048x2048 for OpenGL contexts, but > > that seems to be per context, and I'm not inderested in > > stretching a single context over both screens anyway.

The driver is supposed to just clip at 2048x2048. Some tester concluded it does on Windoze, but I haven't tried it on the Linux drivers. (Though they even have the same bugs as the Windows drivers, so I'd guess they're pretty closely related...) //David Olofson - Programmer, Composer, Open Source Advocate .- Audiality -----------------------------------------------. | Free/Open Source audio engine for games and multimedia. | | MIDI, modular synthesis, real time effects, scripting,... | `-----------------------------------> http://audiality.org -' --- http://olofson.net --- http://www.reologica.se ---
