I've done some benchmarking of my GT 430 card on linux and windows, and I did notice a significant drop in performance on Linux - up to about 30%.

because the linux drivers arent nearly as good as the windows ones. -_-

Computers can do that?

You know the steam folks came out with numbers that showed higher performance on linux than windows. But 30% is meh... You going to get far bigger range of performance from different grfx cards. No point super optimizing for one specific case.

If you are looking to get your performance back on linux playing minecraft, then you have to drop OpenJDK. If you are on Ubuntu or another Debian based distro here is a tutorial to install Oracle's JDK, which is far superior to OpenJDK. If you are using Fedora or another RPM based distro, go to java.com and simply download and install the .rpm

Switching from the default to oracle's increased my performance greatly, better than what I was getting on Windows actually.

My code never has bugs... it just develops unexpected features!

You comparing like with like there?  ie. OpenJDK 7 with Oracle Java 7?  The default OpenJDK on Ubuntu is 6, but 7 is in the repos.  They shouldn't be that much different in speed - they're practically the same code base.

OpenJDK and Oracle JDK share 97% of their source code. I completely disagree with you about the "superiority" of Oracle JDK. Maybe Minecraft is slower with OpenJDK but it doesn't mean than OpenJDK is slower than Oracle JDK. There is still a known bug preventing from running Minecraft as an applet with Icedtea-web & OpenJDK but actually it comes from something else as you can see here. Minecraft, an extremely famous game has a bad support of OpenJDK and you blame OpenJDK instead of blaming Minecraft itself, it's not fair. I have never noticed measurable performance differences when developing 3D applications in Java when running them both with OpenJDK and Oracle JDK.

Yes, that is what I think too.

Which drivers? Proprietary or free open source ones? Don't mix up everything. The last version of Windows having a better support of OpenGL than GNU Linux was Microsoft Windows 98. After that, OpenGL was known to be faster and more reliable under GNU Linux in general.

I installed proprietry drivers from NVIDIA on many Linux machines and never had any problem with it.
I once had a radeon card, but I also don't remember having any driver issues with it.

If you have NVIDIA or ATI, just install proprietry drivers - card manufacturers know best how their cards work.

Adding to this statement, IIRC Valve managed to get better performance on Ubuntu when they began porting some of their games to OpenGL.

Quote
"That the Linux version [of Left 4 Dead 2] runs faster than the Windows version (270.6) seems a little counter-intuitive, given the greater amount of time we have spent on the Windows version. However, it does speak to the underlying efficiency of the kernel and OpenGL" - Valve Linux Team (source)
