Please tell me more...re-download game?
Would that effect just one type of plane then? or any with 50's. I don't seem to have any problems in a 51. Less than 100 rounds usually does the trick, but I'm finding I'm going through hundreds with the F4u plane sets.
Might be a few things. Packet loss from ISP. It could be convergence issues, relative distance to the con or where you're shooting at on a con. I can hop in a Jug, Pony, Hellcat, etc and not have problems.
95% of the time, I'm sawing a wing off. Fuselage shots seem to act like a "sponge" for me, so I avoid them.
