Medium to poor viewport performance with a 1080 Ti

[danio]

Hi all - I recently got a 1080 Ti in the hopes of using it for some GPU rendering and to boost my viewport performance a bit over my old FireGL. I haven't done any GPU rendering yet, but unfortunately both SketchUp and 3ds Max are still somewhat sluggish in the viewport. On a low poly scene Max might hover around 80 fps but give it anything to chew on and it drops way down. I recall my old 580 seemed to do better than that...?

Using SketchUp 2017, Max 2016 and the latest nVidia drivers 38x. Running an older dual Xeon @ 3.5ghz. Cheers and thanks for any tips!

try setting "power management mode" to "prefer maximum performance" and uninstall Geforce experience. i don't know if it makes a difference to system performance but i never install the 3D drivers when installing nvidia drivers.

How old is your Xeon motherboard? is it pcie 2 or 3. 1080ti is designed for pcie 3 so maybe there is a bottleneck there?

Thanks for the response. Yes, could be. I'm running an EVGA Classified SR-2 which is PCIe 2.0. Also relatively old but the CPUs are still fast and overclockable (Xeon 5680's). Not sure if a viewport requires that much throughput?? Or maybe it's just an incompatibility.

I guess it is black Friday coming up, could always turn this old feller into a render node...
