Why is Minecraft so slow?

**h4ck3r** · June 18th, 2011

IF your minecraft is slow, first, make sure you have this installed:

Code:

sudo apt-get install fglrx-modaliases

Then, using Jockey install the proprietary drivers. (you can start jockey from the terminal with the command: "jockey-gtk")

Next, try and run aticonfig --initial, not sure if you'll be able to do this or not.

Finally, following this blog post, add this to your Device section in your xorg.conf:

http://www.linuxinsight.com/your-ati...erver-1.3.html

Code:

Section "Device"
 Identifier "ATI Radeon"
 Driver "ati"
 Option "AccelMethod" "EXA"
 Option "MigrationHeuristic" "greedy"
 Option "AccelDFS" "true"
 Option "EnablePageFlip" "true"
 Option "EnableDepthMoves" "true"
EndSection

Simply put, the goal of this is to first, install the proprietary ati drivers, then add those lines of code to your "/etc/X11/xorg.conf" file's device section. You may need to create one if there already isn't one there. I'll try and help anyone, if you don't understand my instructions, or get stuck in the process. This was hurriedly thrown together and isn't a really complete guide on how to install the proprietary drivers.

My xorg.conf file looks like this:

Code:

Section "Screen"
        Identifier      "Default Screen"
        DefaultDepth    24
        SubSection "Display"
                Virtual 5760 1200
        EndSubSection
EndSection

Section "Module"
        Load  "extmod"
        Load  "dbe"
        Load  "xtrap"
        Load  "record"
        Load  "dri"
        Load  "glx"
        Load  "GLcore"
        Load  "freetype"
EndSection

Section "Device"
        Identifier      "Default Device"
        Driver  "fglrx"
        Option "AccelMethod" "EXA"
        Option "MigrationHeuristic" "greedy"
        Option "AccelDFS" "true"
        Option "EnablePageFlip" "true"
        Option "EnableDepthMoves" "true"
EndSection

Section "DRI"
       Mode 0666
EndSection

I second that, you definitely need hardware 3d rendering, and without driver support, it's simply not going to happen. With your specs, I have no doubt that the problem is the fact it's a driver issue.

Prefaced: I am using a ATI Radeon HD Mobility 4500 series

With the open source drivers I have been having the same low framerate issue.

Unfortunately, when I have attempted the solution of installing the proprietary drivers and editing the xorg.conf file, minecraft simply crashes when rendering the world. I've seen several other threads with the same issue, but no solution other than switching back to the open source drivers (which is the source of the initial problem). Any ideas or are we at the point where we just wait for the problem to be resolved in the drivers?
