bzflag is slow since nvidia-graphics-drivers 390.59-1

[Harald Dunkel <harri@afaics.de>]

Hi folks,

after the upgrade of nvidia-graphics-drivers to version 390.59-1 bzflag seems
to use mesa instead of the nvidia libs. Running

	dpkg-reconfigure glx-alternative-nvidia

doesn't help. Other games (e.g. tuxracer) are fine, so I wonder WTH? I haven't
found the problem yet.


Every helpful comment is highly appreciated.
