How to render Minecraft on the GPU?
- by l0b0
Hardware:
Intel i7
AMD Radeon HD 6970
SSD with plenty of space
6 GB RAM
Software
OpenJDK 6, 7, and Oracle Java 7 (reproducible with all three)
AMD Catalyst 12.8 and open source driver (reproducible with both)
Ubuntu 12.04 x86_64 and older
Minecraft 1.3.2 vanilla and older
On this setup I am getting rubbish frame rates after a short while of playing, dropping from about 45-55 to 15 in a couple of minutes. CPU use is 40-45 even when rendering the opening screen at 1920x1280, and gameRenderer is using about 90% CPU when playing.
Rather than trying to eke out a few more FPS out of an obviously broken rendering pipeline, I really hope to find a solution to make the GPU render Minecraft.
