Multi canvas performance?
Posted: Tue Jul 28, 2015 12:12 pm
Hello
We're making a game where we implement a simple version of deferred shading using a diffuse, normal and AO canvas. Since it's a generally recommended practice, we did it using the new multi canvas feature where you can render to multiple canvases from one shader.
However, we also tried doing the same thing by simply rendering to the canvases one at a time and this turned out to actually give us better performance, especially on my friend's semi-old midrange laptop (nvidia geforce 9200m).
Is there anyone here who has tried out this feature and is there something we need to know or is the feature simply not optimised yet? (It's pretty new after all)
