Nice demo Lee, here are the FPS ratings on my 2 windows 10 devices.
Laptop
ACER SWIFT SF315-52
i3-8130U CPU 2.20Ghz to 3.1Ghz
Intel UHD620 Graphics
12.0Gb Ram
Windows 10 - 64bit.
Full Screen
12 to 14fps @ 1920x1080
28 to 31fps @ 1280x720
Running in a window of quarter screen size
38 to 41fps @ 1920X1080
58 to 62fps @1280x720
So very fast on Intel UHD620 compared to GG Classic, I was getting 12fps, as Classic can only run full screen.
