I have a volume with 512x512,313 dimensions.
I have enabled reslice driver for tracking of a needle. The reslice rendering performance is quite good when I am navigating on only once slice at a time. However when I set the slab thickness to around 75 and have a spacing fraction of 5 I see a huge slowdown to about 1fps. Is this normal? I am seeing that my computer is being CPU limited. I have a i7 with 1.9ghz speed.
