I wonder if Wine will profit from the new X Presentation and Synchronization feature NVIDIA is working on:

I doubt it, unless it will somehow make the drivers themselves faster.
e.g. when I start several instances of my game with Wine on my computer (AMD X2 with Ubuntu and proprietary NVIDIA graphic drivers), performance breaks down dramatically.
Yeah, that's a fairly well known issue with the nvidia drivers, you can also see that when e.g. comparing fps from running two glxgears instances with running just a single instance. Running two instances at the same time will get you much less than half the performance. That issue may be unique to nvidia's setup, I don't get it with the free r600 driver. Though it should be said that performance there isn't quite at the level where it's fair to compare yet.
