Hi Daniel,
Hi there
I have experienced that generally as soon as I use shaders, my DRAW time starts
to increase significantly, and this even if I just reimplement the fixed
function pipeline basic functionality.
I wonder if some out there make the same experiences. Either it is my poor
shader programming (i know about if's and branches that kill performance) or is
there really a price for the added flexibility?
I'm running a GTX TITAN so usually there is plenty of power...
1.) Are testing release mode?
2.) Have you tried to rule out state changes etc. by providing minimal
shaders?
I once had some serious performance problems from lots of unneeded
uniform and texture binding. With the pragmatic shader composition this
vanished.
Cheers
Sebastian
Cheers,
Daniel
