Early-z hardware optimizations can discard extraneous frame-buffer reads and writes. In fact, even older hardware, which lacks these optimizations, will benefit from this step, because more fragments will fail the depth test, resulting in fewer color and depth writes to the frame buffer. See more The pipeline, at the very highest level, can be broken into two parts: the CPU and the GPU. Although CPU optimization is a critical part of … See more Optimization without proper bottleneck identification is the cause of much wasted development effort, and so we formalize the process into the following fundamental identification and optimization loop: 1. Identify the … See more Texture bandwidth is consumed any time a texture fetch request goes out to memory. Although modern GPUs have texture caches designed to minimize extraneous memory requests, they obviously still occur … See more The very back end of the pipeline, raster operations (often called the ROP), is responsible for reading and writing depth and stencil, doing the depth and stencil comparisons, reading and writing color, and doing alpha … See more WebJul 11, 2013 · ic0de. Author. 1,014. July 10, 2013 12:55 AM. As far as my research has shown that there are two different extensions that can be used to force an early Z test in OpenGL 3.0. these are GL_ARB_conservative_depth and GL_ARB_shader_image_load_store. According to the spec they can be used to force …

If you take it beyond that then you're more into the realm of deferred rendering and post-processing. For the most part an early-z approach is almost a hybrid between traditional forward and deferred rendering - by allowing you to avoid expensive shading operations on pixels that do not contribute ... WebNov 11, 2010 · Early Z is a very coarse representation of the scene depth. It works on groups of fragments (8 pixels or so) so that they can be discarded before they are pixel-shaded. As such, you cannot solely rely on early z alone. Having said that I'm not sure if you can enable early Z without having regular/late Z. I think that that is not possible. earnout ifrs
