WebTo ensure early depth test rejection is used effectively, it is important for games to submit all draws that write to the depth buffer first. Doing so builds up the contents of the depth buffer so that early depth testing can reject subsequent obscured fragments. WebGraphics hardware can perform early depth-based culling of fragments before computing their color value (in other words, before running your fragment shader). Consequently, if you utilize any features that would affect that, such as discard, alpha-testing, or manipulating gl_FragDepth the hardware's ability to do that optimization will be compromised since the …
