Hello guys, i have exactly the same setup but with 32 gb ram and GTX 1070 and the same driver, The framerate drops really low if i have at least one bp window open and it shows the nodes with the simulation. if the bp window does not show the nodes, the editor is ok.
Take a lok at what i mean:
In the 2nd picture i have dragged the nodes so they are not showing and the framerate is better.
-------EDIT------
I updated the nvidia driver to 373.06 but nothing changed.
