Hi all, 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 :)
Thanks you bnua
