All fine! I L-O-V-E 2.99!!!
Best thing first: Download and compile totally easy. git clone simgear, git clone flightgear, cmake, make, make install, ready. THAT is how we Linux users love our "unstable" versions!
Much faster on my hardware again - despite tons of eyecandy activated, my beloved EC135 handles really smoothly!
Lots of nice new features, such as integrated fgcom - and no segfault on exit! Uhm, ja... no exit at all... I chose exit and seemingly it stopped working but didn't exit. I HUP'd the task and it left clean, without segfault. Would still be nice to be able to exit FG the "normal" way .
The console log was full of OpanAL complaints: 1328x "OpenAl function alSourceUnqueueBuffers failed with code 40964"...
Talking about sound - I would suggest, putting the regulator for the fgcom volume to the sound settings. That makes it easier to adjust all sound sources in relation to each other.
Otherwise, I'm gonna have a flying weekend and will test and report.
Thanks devs!!!
