Performance test results
Survival mode, uncapped framerate.
Main PC: 200-300 fps. Sluggishness when many chunks recompile.
MacBook: Plays fine, no keyboard focus bugs. The mouse cursor is visible. 20 fps.
Eee 901: 9 fps (16 with closest fog level), very choppy when chunks get recalculated. Just barely unplayable.
I think the framerate when playing is acceptable, but I need to speed up the chunk rebuilding speed. That’s pretty much the most complicated part of the code, though, hehe.
