PostFX: fastest way to copy contents of a texture or backbuffer to another texture?

Unity Engine

Graphics.DrawTexture or Graphics.Blit? I will most of the time, be drawing a smaller area of the texture.

I suspect DrawTexture and Blit have the same cost, I just need to confirm as benching this on my gpu is a fiasco. Any tips?

Eventual output will support mobile too (for what it is worth).

Hey :slight_smile:

I think I’ll give it a good look, I think that’s jolly decent. Btw if anyone else is interested, there’s a paypal donate button there. If you click it, you generally get faster framerates from the god of gpus.

I know I intend to click it next time my paypal fills up. Anyone fancy joining me?

Nice resource Bruno, thanks!
