optimizing iPhone OpenGL ES fill rate http://stackoverflow.com/questions/2785640/optimizing-iphone-opengl-es-fill-rate My framerate is pretty sucky ~20fps. Using the Xcode OpenGL ES performance tool on an iPhone 3G it shows Renderer Utilization 95 to 99 Tiler Utilization ~27 I am drawing a lot of pretty large images with a lot of blending. If I reduce the number.. sucky ~20fps. Using the Xcode OpenGL ES performance tool on an iPhone 3G it shows Renderer Utilization 95 to 99 Tiler Utilization ~27 I am drawing a lot of pretty large images with a lot of blending. If I reduce the number of images drawn framerates.. iphone performance optimization opengl es rendering share improve this question Given that the Renderer Utilization is basically at 100 that indicates that the bottleneck is filling texturing and blending pixels. Techniques intended to..
