Hi everyone,

I use GPU's to process dense clouds inside Photoscan. I had a new rig put together with dual Fury X cards and I was expecting them to pull off between 1.5 and 2 billion samples per second. (my 7990 does about 1 billion). With these two fury x cards I am only getting 400 million right now:(

I have not been able to get the cards to use more than a 6% average load while processing... I have turned off crossfire and disabled ULPS as I found this to work with my 7990 before.

I have tried cleaning old drivers out with fresh drivers in with no luck... I removed a card to see if I could get one card to perform, again, with no luck.

I am very stumped with this. The CPU is an i7 6700k, 64gb of ram, and a z170A motherboard running Windows 10 pro.

Any help would be greatly appreciated. Thanks

Yeah, I installed those earlier this afternoon with no change in performance unfortunately.
