Well the title kinda says it all. Going from SLI to Quad-SLI gave somewhat.. not the boost I expected. I assume this is because games is not optimized for it. So I was wondering if there is someway you can lock an entire core to Physx only (so game only uses 3 cores alá 3-way) or disable only one core so Nvidia CP thinks I have 3-way? Sorry if there already exists a thread or answer to this, tried to search but found nothing.. Thanks!
