I have compile OpenGL SuperBible 5e’s example of Chapter08\fbo_drawbuffers. The source code is come fomr SVN.
When I move the camera with keyboard, I find that the moving is very rough and I cannot moving the camera with hold 2 key (KEY_UP/KEY_DOWN)+(KEY_LEFT/KEY_RIGHT)
However, I run the original fbo_drawbuffers.exe in which the moving is very smooth.
I also run other chapter’s original exe example. The moving is also very rough.
Anyone know that where is the problem?
