So glad you are getting such a great FPS with the Epic.You must have an amazing machine.
I consistently get that framerate on every other plane (such as FlightFactor, SSG, Carenado), but the Epic is stuck around 9-10fps.
My machine is a configured with a Xeon 3.0 Ghz (turboboost to 4.5) with 10-cores (so 20 hyperthreads), a 2 GB SSD, 32 GB of RAM, and a Radeon Pro Vega 56 with 8 GB of VRAM.
X-plane's settings...
Anti-aliasing is less than half.
Number of World Objects is Medium.
Reflection Detail is High, not max.
There are no other AI aircraft.
So, respectfully, I think it may have something to do with the Epic or at least it's configuration. Even with the reflections off in the Epic's options, I'm not breaking 10fps.
Thanks for your input though!
Librain is not and has never been installed. And the refections are all off in the Epic options. So that can't be it. Thanks for the suggestion though!
