Hi there,
I noticed something strange while using the
Custom Tool in F8.
I use it for a simple Despill in the Channels-Tab, nothing fancy
if(g1>((r1+b1)/2),((r1+b1)/2),g1)
It's very slow, it needs around 3-5 seconds to render out the result; I get the loading-cursor and the node also gets the loading-bar on it. It doesn't matter if I feed it int8 or float32 (I noticed the slow render first when I changed it to float, that's why I mention it).
On F7 which I have installed aside of it, I can use the exact same set of nodes (just copy+paste) and it's there in an instant. Of course 3sec render isn't hurt me, but it's adding up obviously, for something that should be close to realtime.
The footage in this case is a JPEG, 1920x1080px
Machine is a Hexacore i7, 970 GTX GPU
Could it be did a bad setup of F8?
