Re: GLX acceleration


Yes, XWin_GL seems to run OK, though I have not seen any dramatic
speedup yet.

It is likely that part of this may be due to memory problems I seem to be
having in the latest xorg downloads, with XWin and now also with XWin_GL.
(I only seem to have these problems in xterm and rxvt, not in a Cygwin
console window.)

`dired` (below) freezes and other processes i other xterm windows bomb:

Subject: Re: new Cygwin has memory problems?

I cannot determine why, but with the new Cygwin base I just installed,
a utility I have used for quite a few years, dired
[http://www.math.utah.edu/~beebe/software/file-tools.html#dired], now
freezes my window.  A `top` shows that CPU usage quickly climbs to
maximum values.

I have to guess that other utilities will have similar problems.

Thanks.

I've tested it with some programs including the glut suite. Some of the 
glut examples fail but most work well.

Just install it and run XWin_GL.exe instead of XWin.exe.

Any feedback is welcome. 

BTW: Only the multiwindow mode is useful with the accelerated server since
the OpenGL drawing surface is not translated to match the window boundaries
in windowed moded.
