Yes, the occurance of screen stutter as you start to fire on a bandit is definitely way, way up since the update. Very noticeable and extremely annoying.
As for bullet hits, etc. I'm repeatedly seeing aircraft that I am carefully tracking as they pass in front of me, where I have a well-prepared deflection gun solution setup in advance at 100-300ft, only to have the bandit pass completely through my bullet stream without registering a single hit sprite or any damage.
Previously, it was more likely than not, I'd at least get one hit, if not serious damage or a kill. I'm talking about a very close, simple and deliberate passing shot. This was a standard bread 'n butter setup for me. Now, starting since the last full update, I see this no hit scenario occur 3-4 times a day with no rhyme or reason.
