After (finally) getting Coot to work install via Homebrew I find that
the rotation smoothness is much, much worse compared to v0.9.8.1, when
the window is enlarged via the buttons at the lower right of the menu
from 1800x1500 -ish to 2900x2300 -ish which is a more useful size.
This seems almost independent of map radius (within reason) or if I
have just a simple difference map with relatively few lines drawn.
I tried playing with shader settings but Basic and Plain do not
increase draw speed and they shrink the drawn area into 1/4 of the
area of Fancy. And they don't draw any faster in that smaller viewport.

Any suggestions for tweaking ?
Hi Phil,
Congratulations on your compilation.
You can investigate the FPS using the Draw -> Frames/Sec...
Using the tutorial model and data, I get about 4FPS when I have focus in
the graphics window (and bizarrely about 8FPS when focus is in (say) the
Display Manager). And that is largely independent of the molecule drawn.
This has been a topic of conversation (amongst other things) on github:
https://github.com/pemsley/coot/issues/33
This has been one of my major concerns over the last 2 months.
Charles and I have been doing some reading - it seems that there are
other gtk-based programs that are slow on MacOS.
The resize buttons were added because the normal resizing method (using
the window manager) doesn't work right. I haven't blogged the window
resize buttons, but Lucrezia tweeted it:

The Basic vs Plain vs Fancy mode framebuffer resizing issue should have
been fixed. I will need to check that.
Paul.
