Minor nitpick about early OS X
There was no acceleration (even 2D!) until 10.2
- rcarmo 2y agoWell, actually, there was. I was doing OpenGL stuff at the time on a Bondi iMac that barely ran early OS X and distinctly remember that.
- ndiddy 2y agoMac OS X versions before Jaguar supported GPU accelerated applications, but the windows were composited in software which caused severe performance problems. Jaguar introduced something called Quartz Extreme, where the windows are treated as OpenGL surfaces and the window contents are textures mapped onto the surfaces. This made OS X significantly smoother on computers with a fast enough GPU and enough VRAM to support it, as the CPU didn't have to spend a bunch of time copying all the window contents to the framebuffer.
