Artifact and Rapid FPS Drop

XMLWordPrintable

    • Icon: Bug Bug
    • Resolution: Incomplete

    • 1.15.0.8 RTX Beta

      TL;DL: Rapid FPS drop from 60 to <10 and freezes, with or without RTX. Full screen artifact 

      Guess: Draw distance blows up to infinity, culling (if any) fails

      Reproduce step: 

      1. Create world "Temples and Totems RTX"
      2. At entrance of Water Temple, look right into forest
      3. Observe rapid FPS drop from 60 to <10 and basically freezes, but game does not crash
      4. When fps is really low, random artifacts stretch from horizon towards camera and covers viewport/screen. Everything flicker, disappear or show corrupted texture
      5. Switch to desktop and back, observe scene is redrawn and FPS recovers to 60
      6. Unless walk away or turn camera, issue cycle (step 3-4) restarts immediately

      Sample locations:

      1. Entrance of water temple (Screenshot(4).png)
      2. Top of water temple (Look towards forest through window)
      3. Corridor beneath water temple (Look into wall)

      Notes:

      1. Restarting game does not help
      2. Issue persists with or without RTX. Sometimes RTX on prevents the issue
      3. CPU, RAM and GPU usage remain reasonable, but GPU memory maxes out according to task manager
      4. Recently installed Windows with all updates. Latest drivers. Fresh install of Minecraft RTX beta today, newly created official map. Stock texture. No mod
      5. In game OSD reports about 6 fps, but perceived fps is barely 1
