The stutters of the last beta are much reduced for me, close to running as il2 does now to be honest, only far better looking! I did notice more shimmering tree shadows from the air - they look like shadows of trees in a blustery wind , blurrily moving around a lot.
Sounds are stronger, some of the MG sounds are very loud; stuck bombers in the 'German - column attack' quick mission no longer get stuck in mid air over the land, though I still had one permanent stuck bit of smoking debris in the air.
Still no damage model for buildings, no matter what's thrown at them.
Nevertheless, a good step in the right direction, FPS more stable with far less sudden big drops and a lot less stuttering (practically gone) over built-up areas.
It would be nice to be able to change the AI strength in the quick missions.
Keep up the progress, I'm starting to enjoy this a lot more
