Drivers are usually kernel-tied more than anything else. I wouldn't expect too much improvement from the FOSS drivers like Nouveau (I suspect the performance required of modern games is still out of their reach), but the binary X drivers from should see some big improvements - any distributions that currently can leverage those would benefit.

In particular, I'm hopeful that the radeon and intel FOSS drivers will improve (although I guess that nvidia said they will help with nouveau now: http://arstechnica.com/information-technology/2013/09/nvidia-seeks-peace-with-linux-pledges-help-on-open-source-driver/ http://arstechnica.com/information-technology/2013/09/nvidia...). I gather Valve has given significant feedback to all three vendors (http://www.pcworld.com/article/2049369/amd-nvidia-ramp-up-linux-driver-support-after-valves-steamos-announcement.html http://www.pcworld.com/article/2049369/amd-nvidia-ramp-up-li... and: http://games.slashdot.org/story/12/08/31/1551230/valve-finds-open-source-drivers-to-be-great http://games.slashdot.org/story/12/08/31/1551230/valve-finds...), and that steam games have, perhaps, stressed the sort of hitherto rarely used code paths that would only show themselves to be broken or unreasonably slow when some compositing DM feature wouldn't work, for example when KDE 4 was famously broken on fglrx for a couple of years, and no one cared enough to fix the driver bug because who plays games on linux, right? Of course that's the closed driver but the same kinds of problems have happened for all the drivers for want of heavy use, and of course they won't be heavily used if they are way broken. Please correct me if I'm wrong, but I think Wayland/Mir support must be added to any driver that will support them, and I believe it's not yet clear that that will be done. Intel has already refused a pull request for XMir support (http://slashdot.org/story/13/09/08/0431242/intel-rejects-supporting-ubuntus-xmir http://slashdot.org/story/13/09/08/0431242/intel-rejects-sup...), and I think the proprietary drivers have no support for either of the new WM's, nor will will they publicly admit to having any plans to implement it. KMS was added to the kernel five years ago this month, and the proprietary drivers still don't support it, although the intel driver does. Imagine a similar outcome for the new compositors, where the vendors don't implement support for a long time, or, worse, where there are factions comprised of certain combinations of driver/distro/WM... that would be bad.

  AFAIK Intel is pushing Wayland. As for Mir, I'm not aware of any group outside of Canonical with the slightest amount of interest.

    Yes, so the question is: if Valve is creating an Ubuntu derivative will they stay with X11 when Ubuntu switches to Mir? As it is now, Steam is easy to install on Ubuntu, and possible, but maybe a bit of a pain for other distros, depending on which one. It would be sad if Steam eventually only worked well on SteamOS, because of fragmentation in the graphics stack. If I wanted to choose my OS solely on the basis of what works well for gaming, I would be running Windows. Then again maybe Intel and Valve will sort of bring some adult supervision to the distros by putting some pressure on everyone to pick one graphics stack and live with it. I'm not sure whether I think this is a good thing or not.
