of course
Good, and 10.7 needs to be on a short release cycle. Finish refining the changes made in 10.6, fix bugs, improve APIs, and maybe roll out a UI improvement... But let's see if Apple will finally correct one of MacOS's longest standing, biggest problem, most annoying issues of all time - sucky graphics drivers/support.
I expect full latest-version OpenGL support, massive improvements in GPU acceleration, full SLI/Crossfire type of capabilities, and full support for nearly any recent generation graphics card on the market. At a minimum the current line of the majors - nVidia, ATI and Matrox should be supported.
I am so sick of lackluster graphics support on the platform that is supposed to be the graphics king. It is beyond annoying, approaching criminal, that I can't just run down to the store, buy a shinny new ATI 5870 or an nVidia GTX 295 and pop it into my Mac Pro and just have it work. Heck, nVidia has a unified Linux driver that works with 90% of their current cards. If nVidia can do it for the wild west of operating systems, Apple can certainly man up and write a dang driver for their tightly controlled OS.
Apple also needs to support more GPU options for their other computers as well, which will need driver support in the OS. And what is the deal with the lame 256MB or 512MB vram configurations Apple? 1GB is now becoming common in average PCs. Get a clue, fix the graphics.
Yes, 10.7 better make a significant improvement in this department. Your bread and butter (graphics) market is starting to bail to Windows and Linux platforms cause your systems can't hack it. Fix the graphics!
