980Ti + Java (Minecraft)

[xBlizzDevious]

Hi all,

 

I recently upgraded my 3 x 7970s in Crossfire to a single 980Ti and the performance is remarkable! Near matching what two 7970s could do on games that supported Crossfire and doubling the performance on those that didn't.

 

One thing I immediately noticed however, was that Minecraft didn't run as fast or smoothly as it did with my 7970 (no Crossfire on Java). So, being an inquisitive person, I looked into what was causing the issue; it seems that the GPU doesn't boost its clock speed when playing Minecraft and so the GPU is running in "idle" mode.

 

I've tried changing the settings for the individual applications (FTB Launcher.exe, javaw.exe, java.exe) and the global settings as such:

Threaded Optimisation: OFF

Power Saving: Prefer max performance.

Neither has improved performance on Minecraft. Is there a way to make the 980Ti register Minecraft as a 3D application and boost itself to "gaming" clocks?

 

Thanks!

Download EVGA Precision X and turn on Kboost. Kboost locks a GPU to its max turbo speed

I think Minecraft is CPU bound.

AMD GPU's do better in Minecraft due to OpenGL.

Are Nvidia GPUs not particularly capable with OpenGL?

 

Also, what use is Advanced OpenGL? I've never witnessed a benefit when testing it. Should it perform better?

I've never been able to figure this out, but the issue is caused from it being a Java game(instead of D3D or OpenGL based). I haven't had bad performance though so I've never really investigated it. If you look at your GPU usage , it will be low since Minecraft primarily uses the CPU(unless if you use shaders, then the GPU usage goes way up).

 

I would try KBoost that The_Stig recommended.

Minecraft can't even when it comes to GPU's.

From what I've heard, Minecraft runs single threaded instead of multi-threaded like most games and relies purely on CPU. I could be wrong though.

I'm trying the KBoost method just now. Hopefully it works.

Partially true. Minecraft is single-threaded but it doesn't only rely on CPU. GPU plays a part too.

As to why I'm noticing a performance issue: I'm playing FTB Infinity with a 64x64 texture pack. I would expect performance to deteriorate when I start building thousands of machines, but I'm only at the early hundreds of machines and it's noticeably laggier than I would expect.
