OpenGL support is a necessity IMHO for 3D apps. As models get more and more heavy polygon wise (M3 and V3 are good examples) everything slows down on the screen when you try to move stuff around. And if you work in shaded mode it's worse. OpenGL is better for previewing lighting and transparencies and textures in general. There is a reason why professionnal apps support it. Nothing will bring a machine down on it's knees faster than a 3d application It only makes sense to download some of the cpu's load to the video card. I have a good video card on my system, and I can easily swing around huge polygon models in Lightwave, it makes a big difference when you are working.
