That is unfortunately only 'fixable' by slowing the Time Compression (TC) to about 128x approx. A little more, a little less, dependent upon the computer. Pearl is probably the worst, but any place that has a lot of traffic spawning, especially airplanes, will do that. Some mods added traffic to the areas, and others have tried to make things more 'efficient'. Are you using any mods? In
Fall of the Rising Sun Ultimate (FotRSU), we've split the Jap_HarborTraffic file into 'layers', like the majority of the rest of the campaign files, and that does seem to help (disclaimer: not scientifically proven). The plan calls for splitting the US_HarborTraffic file next (yikes!), but no timetable yet.
