Update src/com/mojang/mojam/MojamComponent.java #879

Closed joeyismusic closed 12 years ago

joeyismusic commented 12 years ago

This speeds up Java2D by silently converting all image operations to OpenGL calls. The Java2D buffer strategy cannot be used with OpenGL acceleration, so someone would need to write a custom back buffer flipping class.

This slows down the game as hell for me running Linux although I should have OpenGL support.

joeyismusic commented 12 years ago

Perhaps an older JVM? I've heard there are problems with linux as well...

danielduner commented 12 years ago

Is the slowdown a result from not using a proper buffer?

And how does this relate to #858, #870, #872?

joeyismusic commented 12 years ago

This is built-in supported by the JVM, so you don't need native libraries to take advantage of the implementation.

Woah! Unplayable on my Linux machine. I got between 1 and 2 FPS. (Ubuntu 10.04 64bit / OpenJDK 1.6.0_20 and Sun Java 1.6.0_26)

master-lincoln commented 12 years ago

Also unplayable under Ubuntu 11.10 64bit Sun/Oracle Java 6 and 7

Update Just tested and confirmed. The proposed fix at stackoverflow works. Though framerates are similar and not much increased. Could you integrate the toCompatibleImage in MojamComponent line around line 517

Update 2 Nevermind...I commited it.
