Title: RenderWindow::capture() fps down
Post by: youri1er on February 06, 2015, 03:09:19 am

Hi, i've make a game, and like "geometry wars" i want to put a post effect on the result of the renderWindow.

I''ve make a shader "Bloom". The probleme is that : my shader take one parameter : a texture
And the function RenderWindow::capture() decrease a lot my fps.

Have you and idea to improve my situation or to solve it ?

Sorry for my bad english.

You should not use capture to get window content into a shader:

Draw to a render texture then draw the render texture with the bloom shader to the window.
