From 82db4943e011fc65e9a0b87990abb49b898a7782 Mon Sep 17 00:00:00 2001 From: "Jonathan \"Geenz\" Goodman" Date: Tue, 12 May 2026 20:23:44 -0400 Subject: Rework texture streaming and tracking. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a big one: - Reworks the discard signal almost entirely. Now has a normalized 0..1 discard signal: distance x size x channel exponent, floored by staleness and background app state. Shaped by VRAM pressure. - Textures can now scale down to the smallest GPU mip (1×1), independent of the codec's encoded mip count. - Terrain texture LOD now works. Useful for 2K textures and PBR on terrain. Based upon camera distance to nearest terrain patch. - New texture quality setting. Low/Medium/High/Ultra - Caps texture resolution on Low to 1024, and otherwise shifts the discard signal around. Makes distance based texture LOD work a lot more predictably. - We now track last bind state for textures, and discard accordingly. We progressively discard based upon last bind time. - Avatar textures get a residency boost to stay loaded in VRAM longer under pressure. --- indra/newview/llvlcomposition.cpp | 18 ++++++------------ 1 file changed, 6 insertions(+), 12 deletions(-) (limited to 'indra/newview/llvlcomposition.cpp') diff --git a/indra/newview/llvlcomposition.cpp b/indra/newview/llvlcomposition.cpp index 3441e25c6a..eb0261b5e5 100644 --- a/indra/newview/llvlcomposition.cpp +++ b/indra/newview/llvlcomposition.cpp @@ -173,7 +173,10 @@ LLPointer fetch_terrain_texture(const LLUUID& id) return nullptr; } - LLPointer tex = LLViewerTextureManager::getFetchedTexture(id); + // LOD_TEXTURE so streaming math runs (the base-class processTextureStats + // pins mDesiredDiscardLevel at 0). + LLPointer tex = LLViewerTextureManager::getFetchedTexture( + id, FTT_DEFAULT, true, LLGLTexture::BOOST_NONE, LLViewerTexture::LOD_TEXTURE); return tex; } @@ -343,18 +346,9 @@ bool LLTerrainMaterials::makeTextureReady(LLPointer& tex { if (boost) { + // Quality is driven by the streaming math via synthetic signals + // for BOOST_TERRAIN textures in updateImageDecodePriority. boost_minimap_texture(tex, BASE_SIZE*BASE_SIZE); - - S32 width = tex->getFullWidth(); - S32 height = tex->getFullHeight(); - S32 min_dim = llmin(width, height); - S32 ddiscard = 0; - while (min_dim > BASE_SIZE && ddiscard < MAX_DISCARD_LEVEL) - { - ddiscard++; - min_dim /= 2; - } - tex->setMinDiscardLevel(ddiscard); } return false; } -- cgit v1.3
