I was noticing inconsistent frame rates last night, but chalked it up to player density and maybe an accumulation of dust inside my machine that I need to take care of soon. I noted excelent conditions while bombing the bish strats, good in the large bish horde down south, good in a large rook horde which included a CV about mid/mid-upper - but when I upped some B-17s ~3 sectors N NE of the rook horde destined for said CV, all by my lonesome compared to the earleir areas, I noted a couple chops in frame rate for about the first sector. As I got within 2-sectors of the rook horde and leveled off ~8k, I noticed nothing unusual. I never did make it to the upper 1/4 of our (knit) front lines though.
