It's a GeForce 7900 GT. I'm using nVidia's binary drivers, version
1.0.9631.

I did some experimenting.. while Beryl's benchmark feature (<Super>F12)
is running, E-UAE i586 with SDL OpenGL output is fast. I had noticed
that the benchmark feature causes everything to be very smooth and fast
updating (rotating the cube, moving wobbly windows, window burn effects,
water and snow, etc). Perhaps it's calling something in Beryl which
causes everything to update in that instant?

A plain X11 build would be great to try. If you could compile a 32bit
version of E-UAE like that, I'll give it a go.

Both Amiga (only tested AGA with AB3D2 and the boot up options screen -
geeze that's hard to get to, any chance E-UAE could hold both mouse
buttons for us? :-)), and P96 screens are affected.
