I noticed an also strange fps drop. On my level all entitys are ent_created. I use a code which calculate every frame a new universal scale (nothing special, only one line). Every entity has an action which updates his own my.scale with the univeral scale every frame (the level looks much bigger with this trick ). But this process kills my fps!!!!
It runs nearly smooth without this code (setting the universall scale to 1), but with the calculation its unplayable. The calculation of the scale its not the problem, but the update of entity scales.

So my question: How fast is my.scale_x=value;????
Note: every frame for 500+ entitys
