Hi, can you please tell me if the updates for the P3DV4 model are cumulative or not? I have installed the base package csy572_1300 then the update csy752_1303. The aircraft is virtually unflyable due to chronically low framerates, whereas before I had to re-install everything on my computer including Win10, it went well but each update had been installed as they were released.

Any help[ or ideas gratefully accepted.

Thanks, Paul
