Bugs from me that ive noticed:
Hurri series wont start
Tree pop-ups. I took the advice of others and turned the tree's down, restart and turn them up again, but it only works for a short amount of time. Once i get to the point of maximum view from where i initially started the flight, the problem returns. Tree's thin out, and the popup tree's return. Its like the tree's arnt initially rendering, but its still rendering the LOD as if you were getting close to them. Biggest givaway, when this happens, fly low and pause the game. Jump out side and zoom out and in: Zoomed out, the tree is not able to be viewed... zoom in, and the LOD renders and pops up, you can see the leaves and shadows being rendered, but not the tree itself has still not rendered. ill b happy to lend a video of this if needed
Edit: Forgot to mention - The other day i got jumped by a 109, there was no sound of the aircraft being hit. The 1st i knew about it was being heavily wounded and getting the good old red vision

damage on the right wing looked cool though
Transperent cables inside certain aircraft.
