I have installed my Orbx TE GB sceneries from XP11 into XP12 and they are working. But I do find the performance (FPS) often disappointing. Flying around GB in the Zibo Mod 737 I am getting FPS in the region 24-30 But very often the FPS plummet to 1 - 4 FPS and the program freezes until the frames increase again. I am running a Home Cockpit (2 computers). My main sim computer has the following (abbreviated) specs CPU i5 7600k@380 GHz Ram 16.0 GB Dual Channel DDR M'Board Gigabyte Technology Z270 Gaming K3 Graphics - Nvidia GeForce RTX 3060 Ti Storage 232GB Hitachi SSD 931 GB SeaGate Sata My In Game Graphics Settings are in the Med - High range. I have tried differing settings with no obvious improvement. With my hardware what FPS should I reasonably expect? Maybe I need to uninstall and forget Orbx? Thanks for any guidance. William
