Well, we know that for OpenGL-based applications, the DRI stuff
will make a profound difference. Voodoo-3 and Banshee cards will
be able to render in-a-window at full speed - and the nVidia and
Matrox cards will be able to run at full speed without being
crippled by the GLX protocol stuff.
Dunno about the other improvements - but being a 3D person, I'm
very excited about the next release.

Indeed - and so would the games developers. With the performance of
3D hardware doubling about every 6 months, having to delay a game until
your target audience has (on average) 20% more performance is only
a wait of a month or so. On the other hand, an ugly bug in a program
that can't be worked around because it's the fault of the driver can
quite easily delay a game's release by more than a month!
This is especially true for the smaller games companies who will
have a harder time getting the board developers attention when
something goes wrong.

Probably the lack of support for USB sticks, digital sticks and
force-feedback sticks. USB is likely to get solved VERY soon because
USP support is supposedly in the next Kernel rev. Non-USB digital
sticks - and especially the force-feedback ones are VERY problematic
because Microsoft has the largest market share with those devices
and you can guess how enthusiastic they are about supporting a Linux
driver for them :-)

Yep - and in any case, we are talking **GAMES** here. How many commercial
games use any of that GUI stuff from the OS anyway? Since Xmas, I've installed
RailRoad Tycoon, Quake-3, Civ and Heretic II - not *ONE* of them uses the
GUI provided by the OS. They all have custom written GUI's that are utterly
unique to that specific game.
Games hardly do anything other than sound and graphics that envolves the OS.
(...well - maybe networking...)
Even when they are doing their graphics stuff, they are using a small subset
of the relevent API's. Quake-3 only draws textured triangle strips - there
is probably 90% of the OpenGL API that it never uses. 2D games blit LOTS
of rectangular or non-rectangular sprites - but they don't need fancy API
to do that...it just needs to be blindingly fast.
