Plauged by stutter when zooming in on maps. Have now tried different bearing overlays, and found it indeed to be the reason.
The GWX overlay is 11MB... (original was 2kB
). Found Pato's Bearing Overlay 3.0 and it really makes all the difference. Went from 4-7fps to 80fps... and I think Pato's overlay is actually sharper?
Stutter on bridge too when panning past crew. Solved by replacing the 4MB files with 760kB ones... also rescaling medals/no medals. Huge difference. 20-40fps to now over 130fps...
