My first thought would be that of course most current= cards are inadequate. All software overwhelms the hardware until newer har= dware is made to meet the challenges of the software and then the cycle sta= rts over.

Looking ahead, I would check out the USB= C/Thunderbolt 3 GPU expansion chassis and I would add as many cards with as= much RAM as I can afford.

Good Luck.

Thanks for the info although it confirms that VR Tools might not be = ready for primetime. That's my guess too. But without some way of calcu= lating, do we know if 32GB is enough? And if SLI will get you there or does= it have to be a single card? The lack of info on this is disconcerting.
