now FlightGear OSG is running almost at the same speed (sometimes
faster) than plib for me.
FreeGlut was the culprit. Switching the the good old glut gives another
10% FPS boost. And it fixes a bug: For me the c172p with freeglut is
accellerating itself at the runway without using the throttle. With
glut-3.7.6 it stays at the starting position.
Yes, a small gain ( 10%) here. The big improvement was down to Mathias'
recent changes. But most important is that with GLUT the bug in the start
for the Hurricane/Spitfire/Seafire has been fixed.
It remains the case, that while cockpit views are now comparable, or better
than plib, external views are still about 25% down, and usually less than
the cockpit view. My guess is that transparencies have a disproportionate
affect on frame rates.
