Help, Java runs only with crappy graphics and sound.

Issue: Java uses OpenGL to interpret graphics. Especially if you are a MAC user it is possible that your version won't live up to the highest quality standards.

Solution: Make sure to have installed the latest version of OpenGL for your OS as well as the latest version of Java.

Alternative: You can always try to run an older Java version. But be aware that this might create a security risk for you.
