One thing I've forgotten to mention in my previous replies is that it's really unfair to compare the performance of an editor (MBC) with a viewer (LDView), even if both are running on the same machine. A viewer doesn't have to worry about adding, (...) (20 years ago, 17-May-04, to lugnet.cad.dev.mac)

(...) Since we seem to be talking about performance measurements, what do you think about comparing the the current yardstick: l3lab? On my fairly old 500Mhz PC with a TNT video card l3lab prints this for stats. Timing: Load: 1222 ms Draw: 8442 ms (...) (20 years ago, 17-May-04, to lugnet.cad.dev.mac)

(...) Maybe you're running into one of those weird oddities of the Apple opengl drivers. For example rendering to the GL_FRONT buffer really renders to a hidden back buffer. There are times where this setup causes you to use triple buffering, which (...) (20 years ago, 17-May-04, to lugnet.cad.dev.mac)

(...) Ah, that explains my mysteriously low load time. I did the measurement on the 2nd try. So, I'd say anything drawing in the fps range is certainly getting some benefit from the opengl acceleration. Don (20 years ago, 18-May-04, to lugnet.cad.dev.mac)
