pixel-bound

Pixels are most probably the slowest part in your pipeline. The bigger the resolution, the more pixels we have to be shaded!
Pixels are most probably the slowest part in your pipeline. The bigger the resolution, the more pixels we have to be shaded!
So how to check if we’re pixel-bound? While running our game, we can press ~ and enter: r.ScreenPercentage (for example) 25 or r.SetRes 480x270, for example. Then if your framerate improved a lot, then it means you’re pixel-bound. Not for example vertex- bound or memory-bound. The pixels are the problem.
