I upgraded to 4.11 p5 just to see what would happen and I was able to build and package my game without problems and the frame rate is actually better with 4.11 than it was for 4.8 and 4.9. I don’t know what is causing the problem for me with 4.10, but I will just stay on 4.9 until 4.11 is ready. No need to keep this ticket open as far as I am concerned.
