Thanks for this helpful page.
I am looking for a way to disable the animation for going full screen.

I only use Full screen mode when I double click a YouTube video, and the 2sec animation that follow is incredibly irritating. Any suggestion is welcome.

This is more about the animated powerpoint effects and disabling them. This is not about disabling the features that they animate. I would also like to disable the full screen business, never user it and it activates by accident causing disorientation and distraction.

@aminozuur you can find a checkbox in settings > accessibility > display to reduce animations. Entering full screen will be much faster.

Doesn't work for my 10.15.2. Hide/Show animation is still shows

I use El Capitan and the "Reduce Animations" thing came later. Some more settings that (in my experience) help are:

1. System Preferences > Show Scroll Bars = "Always" (the implementation for the "Auto" setting seems very expensive!)
2. System Preferences > Use LCD font smoothing when available => unchecked
3. Preview Preferences > smooth text & line art => unchecked (expensive)

I am using a MacBook Pro, 16 Gb, i7 with an NVIDIA 650M in docked mode on a 2K thunderbolt display (so anti aliasing is superfluous). Using lexrus' script and these settings the GUI runs as fast an ASUS RoG G703 with an NVIDIA 1080 also hooked into a 2K display.

On the native MacBook Pro screen, this stuff is less or un-necessary.

Thanks a lot lexrus ...

I get awful migraines from this type of animation. I don't think a different screen would change that. And the defaults write -g NSWindowResizeTime -float 0.001 doesn't work in 10.14.6.

Any update in 2024? the window switching animation is killing me
