This is true, and I vouch for gamedevs to first test other engines to see the differences.

Calculating for the future is extremely important in pretty much everything.

Also I wouldn’t say there would be performance issues, unless you somehow completely screw up coding and compiling said code.

Projects should work on top of a bottom layer, or translation layer as it’s sometimes called; game logic calls for functions from there, instead of directly from the engine. This is also important for code security.

_move_entity might be calling the proprietary unity_move_object with a different reg stack, but when compiled the performance should be +/- 0.
