well i agree with one thing, 3d applications needs to seriously start digging in on the gpu performance for more then just opengl preview, it needs to start helping out the cpu with the final renders, alot of seriously wasted performance there on most modern day rigs. make it optional if youre concerned with people without a decent gpu. however theres a big difference tho, even tho a game is real time its still like a big sandbox (a premade box with limits and posibilitys) compared to the virtualy unlimited things your 3d applications needs to handle, that sandbox environment helps out quite alot when it comes to games. but yes, 3d apps could be so much quicker to work with.
