Recently (about the time of the last MacOS update) I noticed a inability to run my game full screen without major FPS drops. I have attempted a full reinstall but the issue persits.

I am currently playing in a window, which is acceptable but was wondering if there was something I could adjust to all me to go back to full screen playing without having to deal with 14 FPS in an empty world. UPS is holding at a stead 60.

Any help with possible ideas on the problem, or a solution would be greatly appreciated.

Thanks for taking the time,

Same for me on windows, seems to be related to Atlas Texture Size Option.

Default was "Largest Possible". Changing it to even 8192 made it a lot smoother for me, 4096 made it smooth as butter. In early betas of v16 it was like that for me too, but it was smooth towards the last few beta versions so dont know what changed upon release.
