Hi, I have a fresh install of FSX-SE with the but am seeing a very weird FPS problem specific to the ERJ-145 v2 whilst moving on the ground. As soon as I get above 1KT the FPS drops dramatically (from 40-50 FPS to 20-30), but jumps back up again the moment I leave the ground. I've tried running with clear skies to avoid clouds sapping any FPS but the problem persists and it seems specific to the ERJ 145. I can't understand why it should just be happening on the ground, and why it is fine while the aircraft rolls gently at <1KT but kicks in at anything greater. Has anyone else experienced/reported this issue or any ideas why it might be happening? With clouds and payware scenery/airports I suspect the FPS drop will make the ERJ unusable. System specs: Intel Core i7-4790K @ 4.00GHz, 16GB RAM, nVidia GTX 960 (2GB), Windows 10 Home 64-bit. Thanks in advance for any help anyone can provide - I'm stumped! Alan.
