Uncapped framerate in certain screens causes high levels of GPU usage.


    • Confirmed

      Minecraft's GUI screens (with no 3D rendering in the background) don't have a cap on the framerate they run at. This means that they will use up a lot more GPU power than needed.

      Here's some example framerates taken from 13w10a (so I could test the texture pack screen in-game).

      Title screen: 36 FPS
      World List: 780 FPS
      Server List: 725 FPS
      Options (From Title): 785 FPS
      Language (From Title): 710 FPS
      Texture Packs (From Title): 785 FPS
      In Game: ~95 FPS
      Options (In Game): ~95 FPS
      Texture Packs (In Game): ~95 FPS

      Of interest is that the texture pack screen has the same forced background depending on where you access it from, but it only displays the abnormally-high framerate if you access it from the title menu (or the options screen in the snapshot).

      So it's a bit more taxing for the GPU to sit at the world select screen than it is to actually play the game.

      Crash report 1 (02.35.03) is from 1.4.7.
      Crash report 2 (02.38.24) is from 13w10a.
