From bf3acbf388406f736286d990adb5f35a9023c390 Mon Sep 17 00:00:00 2001 From: x2048 Date: Sun, 25 Jul 2021 12:36:23 +0200 Subject: Distribute shadow map update over multiple frames to reduce stutter (#11422) Reduces stutter and freezes when playing. * Maintains double SM and SM Color textures * Light frustum update triggers incremental generation of shadow map into secondary 'future' textures. * Every incremental update renders a portion of the shadow draw list (split equally). * After defined number of frames (currently, 4), 'future' and 'current' textures are swapped, and DirectionalLight 'commits' the new frustum to use when rendering shadows on screen.
