Noticeable FPS drop while holding a GT6 tool and holding down the right mouse button

I might try attaching JVisualVM to my Minecraft instance later to see if the sampler can identify where in the code the JVM is spending all of its time.

That would be awesome if you could! It’s such a substantial frame drop that whatever is happening should shoot right to the top of the listing.
