Yo
I have a fairly heavy patch that runs reasonably fast ~40fps
I want to pipet 12 values from the (rather large) main output texture, to control some lights.
I’d expect to be able to downsample the texture to 12*1px in a render pass, then pipet that small texture at a relatively low performance cost. Making the texture smaller doesn’t help though, and the fps drops to 20fps.
In fact, I just noticed that as soon as I connect a renderer > dx9texture > pipet together, the framerate drops to 20fps. Even though they are not connected to anything else!
What gives?
