Kelsi c4d0a21713 Improve shadow performance: halve resolution, 9x fewer PCF taps, throttle depth pass ... - SHADOW_MAP_SIZE 2048→1024: 4x fewer pixels rasterized in depth pass - Replace 9-tap manual PCF loop with single hardware PCF tap in all 4 receiver shaders (terrain.frag, wmo_renderer, m2_renderer, character_renderer). GL_LINEAR + GL_COMPARE_REF_TO_TEXTURE already gives 2×2 bilinear PCF per tap for free, so quality is maintained while doing 9x fewer texture fetches. - Throttle shadow depth pass to every 2 frames; OpenGL depth texture persists between frames so receivers always have a valid shadow map. 1-frame lag at 60 fps is invisible.		2026-02-18 21:09:00 -08:00
