I just spent awhile running the Half Life and Call of Duty 2 games and verified
that anti-aliasing works with OffscreenRenderingMode set to pbuffer or
backbuffer.  I just let wine pick whatever RenderTargetLockMode it wanted.

OpenGL games actually only seem to suffer around a 20% to 40% drop in FPS with
backbuffer and anti-aliasing set to 2x, so Half Life and COD are playable, and
the quality of the AA looks quite good. However, with AA any higher the FPS go
down very quickly. DirectX games were not playable in backbuffer mode at all
though. I literally almost ate a whole bag of microwave popcorn waiting for
Need for Speed Pro Street to get to the first selection screen.

And neither OpenGL or DirectX games run very well with pbuffer, although they
do work and you can see the beneficial effects of AA.

So there definitely appears to be a problem with AA and FOB, at least with the
games I'm using.

I just want to say again though, the quality of the AA was very good, just as
good as under Windows to these untrained eyes. If it worked with FOB it would
be awesome!
