There is no visual or simulation speed difference for G00 or G01 in simulation mode. You should be able to tell those moves by looking at the toolpath. Feeds are solid lines while the rapids are dashed lines. You may need to play with the settings in the simulation toolbar to get the 'jerks' out. It also helps to have alot (4+Gb) of system RAM and 2+Gb of RAM on the video card.
BTW, if you have not yet noticed, the TURBO mode provides poopy results. I only use TURBO to check that I am not rapiding thru areas that should not be.
I hope this helps. Have you been to the CAMWorks forum?
