6. Texture Priority

• Locate an object in the distance with an unloaded or blurry texture.
  • You may need to fly to a new area or log out / log in.
  • example test location: http://maps.secondlife.com/secondlife/TextureTest/161/82/44
• Zoom in on the object so that the blurry texture is large and centered in your view.
  • The texture should quickly improve to the correct resolution, before other nearby textures do.

7. Full Res

(Removed)

8. Texture Memory management

(Removed)

9. Texture Cache

• Clear the cache: login to SL, open preference -> setup: reset the cache, click "OK" when asking if clear the cache. At the beginning of the next login, the entire texture cache will be wiped out.
• Save to cache: re-login, open the Develop menu with "ctrl+alt+q"(SecondLife 2.x), open the texture console by "ctrl+shift+3". Watch the final status of each fetched texture is "WRT", which means the fetched texture is written to the texture cache.
• Load from cache: re-login, go to the places you visited last time, open the texture console by "ctrl+shift+3", watch the status of each fetched texture. There should be no "SIM", "NET", or "HTP" status for most textures, especially for those "white" colored texture items shown in the texture console. The texture fetching process should be much faster.
• Exhausting test: this may take a long time. Set the texture cache to be minimal (64MB) (Going to "preference -> Setup -> cache size"). Visit a lot of different places to make the cache full. To determine the available texture cache use this calculation: 20% of the cache size goes to VFS. 20% of the rest goes to store headers of textures. So the texture cache size is 0.8 * 0.8 = 0.64 * cache_size. Example: With Viewer Cache Size set to 64 Mbytes, the Texture Cache size is 40.96 Mbytes. To determine when the texture cache is full Open the Texture Console: Develop > Consoles > Texture Console and observe there will be a line output like Cache: 11.0/40.0 MB (The first value is the current size of the texture cache / The second number is the total allotted texture cache) When the texture cache is full (like Cache 40.0/40.0 MB), 20% of its contents will be purged based on Last Recently Used. Example: With a viewer cache size set to 64 Mbytes, 40 Mbytes are available for texture cache. When that 40 Mbytes is exceeded in texture cache shown in the Texture Console, the texture cache will purge 8 Mbytes and then be sized at 32 Mbytes. Watch that viewer and cache works fine when this 20% purge occurs when the texture cache overflows. Every time when re-login to the last place where you quit SL, most textures are still loaded from the cache. There should not be any freezing or crash happening.
