      New MC launcher. JVM arguments is -Xmx2G
      Executable is unchecked, it automatically runs the stock version of MC that you guys provide MC with nowadays.

      MC is much laggier using your version of MC. Running the old MC, with a 64-bit 1.7 JVM makes MC a lot faster.

      With the new JVM, MC seems to need to allocate a lot of memory, doing a full cleanup cycle every 3 seconds or so, making a huge lag spike (the Memory jumps up and down quickly). Every now and then MC crashes (once in an hour or so, see the JVM crash report attached.

      Oh, and I have UAC completely disabled, doesn't fix it.
