I'm trying HDRR. My application (osg v1.2) turn in real time (>60fps) using
FBO with texture 16bits (GL_RGBA16F_ARB), but when I try with FBO
32bits(GL_RGBA32F_ARB) my frame rate is null. Is it normal loosing almost
all performances? :s
There is a minimal hardware configuration to do HDR32? There is something to
do more than change the internal format of texture attached with FBO?
If someone have an answer :)
