Hello guys,
I am using rendering on demand in a lot of my scenes. So while the scene changes I decrease the quality and if everything is static I increase it to max settings. Most powerful setting is the hardware scaling level. I would love to supersample the canvas to infinity but unfortunately that’s not possible. Depending on the device the browser crashes if I set the hardware scaling level too low.
My question is: Is it possible to determine the lowest hardware scaling level possible? Since it’s only necessary to render one frame with this setting I want to push it to the edge.

Unfortunately no. we do not have access to the browser memory and thus we cannot estimate the max value 
Too bad
Does the lowest hsl depend on the scene? Or doesn’t it matter how complex the meshes are and how big the textures are?
does not depend on the scene 
so half good news!
You can try using lowest values iteratively until the render width (or height) does not increase anymore:
On my computer, the final level is 0.125 (size=6072x5463) with the default Playground render window size but only 0.25 (size=7438x4460) if I widen the render window before starting the PG.

I love it! I will make some tests with it. Thank you very much!!!
