Minecraft FPS irregular in fullscreen, but reporting 35-45

  • Minecraft FPS irregular in fullscreen, but reporting 35-45 l0b0

    How to reproduce:

    1. Start the PC, and log in to Linux Mint 12 (although I'm pretty sure the same issue appeared on Ubuntu 11.10 as well)
    2. Start Minecraft
    3. Maximise the window
    4. Have smooth experience at 35-45 FPS
    5. Quit Minecraft
    6. Start Minecraft again
    7. Maximise the window

    At this point I'd expect Minecraft to behave in the same way as before, but there's an important difference: Most of the time (but not all of the time) when starting Minecraft the second and subsequent times after logging in, even the title screen will be choppy, looking like a movie player dropping frames all the time. The tilted text on the main screen doesn't bounce smoothly, the background doesn't pan smoothly, and the game doesn't play smoothly. The last bit is the most puzzling: It still reports 35-45 FPS, but it's clearly not displaying at that rate. Also, it still seems as smooth as before if I restore the original window size.

    This "lag" doesn't happen every time I start Minecraft, so sometimes it's enough to just restart it a couple times, maximise, and see if the title screen is animating smoothly.

    The fact that Minecraft reports 35-45 FPS, I've got the latest ATI drivers (and saw this issue on earlier versions as well), and that I've had some complete hangs when maximising a lagging Minecraft window (only AltGr-SysRq-REISUB worked, not even Ctrl-Alt-F1), leads me to believe that the window manager, X or graphics driver is to blame.

    Anyone having the same issue or tried-and-tested fixes?

  • I suggest installing Optifine and seeing if that fixes the issue.

    While I know that the issue isn't your PC not being powerful enough, its still worth a shot.

  • Give it more RAM, add Optifine, and Update your video card drivers. Update Java as well.

  • Recently I've encountered a problem. Well, it wasn't a problem at the beginning, but now my PS3 can't even start downloading a patch. What happened step-by-step: I booted my PS3 Started the game (Injustice: Gods Among Us) PS3 asked if I want to download and install the update I chose "YES" and waited At around 84% (or so), my internet went down. When it was back up, PS3 wasn't able to continue the download, so it was still calculating(and adding) the time remaining. After a while I turned it off (by holding power button) Repeated steps 1-4 again PS3 wanted to start downloading the new

  • I've noticed when in the menu, there are a few undocumented keyboard shortcuts. I've found the following so far: 1 appears to work the same as Enter 2 will compare items in the menu 3 will automatically junk something for you I've noticed inconsistent behavior in dialogues - when speaking to a blacksmith trainer to see if these shortcuts worked at all in dialogues, I managed to spend my life's savings on training by hitting 1 in that context. What other interface-specific keyboard shortcuts are there, and are they documented anywhere?
