           Summary: New DirectDraw hardware acceleration slow on nvidia
                    driver 100.14.19 in Starcraft
           Product: Wine
           Version: 0.9.51.

Outfrom from glxinfo using nvidia-drivers 100.14.19.

As I understand it, Wine can use a new way of accelerating DirectDraw, using
OpenGL, since version 0.9.47, which can be activated by setting
DirectDrawRenderer to opengl, and RenderTargetLockMode to "readtex". When I
still used Nvidia drivers 87.something, StarCraft (which uses 8 bit color) ran
perfectly smooth. However, now that I've upgraded to 100.14.19, it runs
extremely slow, but only when selecting an Overmind or an Egg. When selecting
any other building or unit, it runs as smooth as before.

When running with GDI, the game also runs slower with an Overmind selected.
However, not as slow as in OpenGL mode.

- Gentoo Linux.
- Wine: 0.9.51 (also tested 0.9.50, which was the version I used together with
the older nvidia drivers).
- Video card: GeForce 6600 LE.
- nvidia-driver: 100.14.19
- CPU/RAM: AMD Athlon X2 3800+/2GB RAM.
- Glibc: 2.6.1.
- GCC: 4.1.2.
- Kernel: 2.6.22-gentoo-r5.

Output from glxinfo is attached.
