Hello
So, I've been using maya forever and have just made the leap to redshift and GPU rendering. Purchased a Gigabyte Geforce GTX 1080ti gaming for my 2010 12 core mac pro 5,1 , 64 GB ram with High Sierra. Pleased with the render results I went ahead and purchased a Geforce GTX 1070ti. Everything's peachy. Found a great deal on another 1080ti (an msi aero), added an external PSU (EVGA 850GQ) and.... disaster. Well, not really, the performance is just terrible - screen lag, maya (and everything else) becomes unusably slow (not just rendering but interaction as well).
I've done some experimenting with different cards in different slots and the results are all over the place: geforce 1070ti in slot 1 gigabyte 1080ti in slot 2 = fine,
msi aero 1080ti in slot 1 with gigabyte 1080ti in slot 2 = fine,
gigabyte 1080ti with geforce 1070ti in slot 4 = lag and poor performance,
which made me think perhaps the problem is slot 4, however I was able to recreate the lag with two msi aero 1080 ti's in slots 1 and 2!
Thoughts anyone??
Yes, I have the latest Nvidia web driver (I think) 387.10.10.40.124
