I'm trying to paste a Canvas which is capturing a layout into another Canvas, but with halved/quartered/reduced resolution.
The reason for this is that I need to apply several layers of PS blur and that causes a major slowdown at full res.
Using the Resize Canvas options even before the Paste action cause the capture to be either zoomed in or distorted making this approach seemingly pointless.
A workaround I've managed to use is creating an itermediary Canvas, which captures the source at full res, gets shrunk to the lesser res and gets pasted into the final Canvas, which has to be at the lower res since game start. Lastly that Canvas gets upscaled to the proper res.
I seem to get a performance increase which more or less scales with the downresing factor, but this solution is very cumbersome - does anyone know of a better way to directly paste stuff into Canvas, but with a lower resoltion?
