"OpenGL is a lot faster on my system in Carrara Pro 5 Beta than Carrara Pro 4 was. The floating points are still a problem for imported hyper-smoothed objects." What I found incredible is that with OpenGL I can now place a texture that is a video onto an object and then play the animation and see it in near realtime in the 3D view (textured shading). Something that was no where near possible in C4 or earlier. Its also a big plus with animating with bones. As you can see the movement play back smoother and faster.
