I'm wondering what version of OpenGL is best for Minecraft. Currently, I'm running Windows XP (2G RAM), OpenGL 2.1, JRE 5 (and Minecraft 1.2.5, haven't downloaded the latest yet).

Minecraft runs well (although I have Render Distance set to Normal, or it's too slow).

Would it be worth the hassle, of upgrading/installing the latest OpenGL (4.2)? What effect would it have on Minecraft, if any?

Update: I'm running 32-bit Windows XP, with a GeForce 7600 GS 256MB (fairly old, I know). As for OpenGL, it came with XP. When I checked with an OpenGL Viewer, it told me the version was 2.1. Whether that was what came with XP, or was installed by Minecraft, I don't know.

minecraft comes bundled with its own opengl library... –  z ' Aug 7 '12 at 3:14
    
@yx, any documentation for that? If so, sounds like an answer. –  Cyclops Aug 7 '12 at 10:45
    
@Cyclops I think he's confusing OpenGL with LWJGL. LWJGL comes with Minecraft. –  smoth190 Aug 8 '12 at 0:21
    
The performance problems in Minecraft most likely don't come from OpenGL. –  Gnoupi Aug 17 '12 at 14:10
    
Unless you have Advanced OpenGL on. –  Timtech Aug 19 '13 at 19:35

OpenGL drivers are usually part of the graphic driver package (though there's also a default implementation on the Windows installation media); in your case, NVidia's. They have to be to access the hardware on a low level and to know which extensions and capabilities are implemented by the hardware.

So the basic answer is: Update the drivers for your graphic card. That's the most recent version of OpenGL you're going to get. That's also the most bug-free, usually, and thus recommended.

When you say Windows XP with OpenGL 2.1, do you mean your graphics card supports up to OpenGL 2.1? If that's the case, don't upgrade. I didn't think you could even upgrade OpenGL, and I've never heard of anyone upgrading it. Minecraft uses LWJGL, and I don't know if it has it's own internal OpenGL library which can't be upgraded.

No matter what the case, I would think a lower version would run faster. I know if I run games on DirectX 8 instead of DirectX 9, I get way better FPS, even if my graphics card supports DirectX 11.

If you have a 64-bit operating system, but are using a 32-bit JRE, that will make it run slower, so make sure that's all sorted out!

The link for LWJGL says "provides developers access to high performance crossplatform libraries such as OpenGL" - doesn't mention installing it. –  Cyclops Aug 7 '12 at 10:44
    
@Cyclops - OpenGL most of the time installed by the program that requires it. Direct X is also installed in a similar way. In both cases only the version the game was compiled against can be used. –  Ramhound Aug 7 '12 at 11:41
