I just discovered how to speed up etqw. It looks like it doesn't use it own libSDL:
# ldd /usr/local/games/etqw/etqw.x86
linux-gate.so.1 => (0xffffe000)
libSDL-1.2.so.0 => /usr/lib/libSDL-1.2.so.0 (0xf7eb8000)
Here should be a symbolic link :
ln -s /usr/local/games/etqw/libSDL-1.2.id.so.0 /usr/local/games/etqw/libSDL-1.2.so.0
and a change in the start script (etqw) from:
after that etqw started with command:
'/usr/local/games/etqw/etqw' +set com_allowConsole 1 +seta com_unlock_timingMethod "1" +seta com_unlockFPS "1" +seta com_unlock_maxfps "90" +seta com_videoRam "256"
in 1280x1024/Normal/AF8x/all_set reach now constantly 90-100 FPS during online play (in start menu I have still 30FPS )
It is highly recommended to set cpu scheme to performance level.
