To be exact i expected to be able to:
Set the Rendering Resolution in runtime.
With anti aliasing, yeah, i know, i just realised it, thats my fault.
And with Fog, i actually thought about Fog like, well, yeah, Fog.
^^ But that was never really a problem, since how i imagine it can be done with a 2D texture like i currently do.
So yes ok, to round it up, in all honesty, if i could set the rendering resolution at runtime i would be glad enough.
But that is only set for the 3D canvas and not the 2D. As far as i can tell.
Sorry that i had some false expectations (Talking about Fog and AA(I was a bit overreacting))
when i think about it afterwards, it's kind of clear that it wouldn't be like i thought it would be.
