After downloading correct binary package install it as other programs on your OS.
It’s already distributed for different graphic cards & drivers: DirectX, OpenGL1.x, OpenGL2.
OpenGL2 version produce best graphic quality, but need more powerfull GPU for run.
You can start YSFlight executable in few ways:
by clicking on executable file;
run from console with parametres (see bellow).
On Linux there is support for ALSA and Pulse-Audio backend:
../plugin/sndYsflight32.so../plugin/sndYsflight64.so../plugin/sndYsflight32-pulse.so../plugin/sndYsflight64-pulse.soIf ALSA not work for you try use Pulse-Audio by default. For this rename delete files of ALSA plug-in and rename sndYsflight**-pulse.so to sndYsflight**.so and restart YSFlight.
Using “YSFLIGHT Command Parameters” you can run in needed mode directly from console.

If you have Intell, ATI/AMD or other GPU then try next command:

~ $ vblank_mode=0 primusrun {path-to-ysflight-executable}or
~ $ optirun {path-to-ysflight-executable}Also read more about “PRIME” technology for Intell, ATI/AMD or other GPU in its docs.
