I can't play starcraft under wine because the performance is pretty terrible. The problem is that starcraft wants to use 8 bit color, and translating that to output on x running under 32 bit color is very cpu intensive.
We do not plan to add depth changing to RandR along the lines of the original proposals. Rather, we intend to support depth changing in compositing managers. Hardware compositing support should, on current hardware, be more than fast enough, once hardware accelerated compositing managers are commonly available.
