>>Not true – it runs better under OS/2. I haven't tried to run it under OS/2, but I seriously doubt that it runs better. what is your definition of better? Is it more stable? Is it faster? That multitasking stuff is nice, but what are you sacrificing for rendering speed. Is it twice as slow? Maybe three times. I'm curious. I'd like to see some benchmarks. Again, I must emphasize that I have never used OS/2. I do use windows and Unix and DOS. My experiences from using AutoCAD on those 3 OSs is that the DOS version is much faster. Whenever you multitask, you are spreading your system resources to various tasks instead of devoting them all to one task. That is where you can take a serious performance hit. If I change a material or a scene and want to rerender it, I don't want to wait because I've got some other thing going on in the background. The faster the better. I am more productive if it takes less time for a scene to render as I can go back and modify it and rerender it fast. I have found that the more programs you run in a multitasking environment the slower each app is going to be. This is true both in Windows and on Unix platforms. I've run 3 sessions of AutoCAD on my SUN and in windows and found that it didn't make me any more productive since I was always waiting for one session to redraw or zoom or do something CPU intensive. As soon as I closed all the session except one, AutoCAD sped considerably and I was able to get more done. Anyway, these are my 2 cents. To each his own OS. I like DOS cause I am a speed freak. I feel the need for speed. That is true for everything I do, ie driving, bike riding, windsurfing, rollerblading, skiing and of course rendering and CAD.
