Hi
I was tired trying to find a solution for the frames problem with the Wilco E-jets and 737 models when using Windows 8, 8,1 and 10 and Wilco stupidly is not offering support for the latest windows, so I decided to do it myself... Im publishing this because I'm sure I'm not the only one with this issue and there is no other place where solution for this matter has been given so far so here it is:
First
Find the Feelthere folder and locate the SETUP program that enables to setup the frames per second and other graphic settings and use any setup you want, then right click on the icon and use compatibility mode for windows 7 and run as administrator.
Second
Run Fs2004 only as administrator, DO NOT USE any compatibility mode.
That's it
Now you will find the frames run as smooth as you used to have on win 7.
best regards
Rodolfo :D
