Max # of layers in a layout

I'm planning to "cheat" the 2D nature of C2 using scaled layers to simulate a 3D room looking top-down. I'm using the personal version of C2, so I know I'm not limited to four layers, but I'm curious as to how many layers I can use before I may start noticing problems. I also understand this may certainly vary per computer and other factors (ie: assets in the project, mobile platform vs PC). I'm just looking for some general info to be mindful of.

Thanks!

Quote from Ashley:

[quote:1mmytww9]Layers have no performance impact unless you change the layer opacity, blend mode, enable "force own texture", or add WebGL effects. Otherwise there is no reason for layers to reduce performance.

So basically, what you do with the Layers is the main factor.

That'll work! Thank you, zenox98 and Ashley from the past!
