....It works as close to perfect as one can desire. cad.onshape.com/checkreturns some tens of millions tri/sec under the latest firefox. No graphicsartifacts whatsoever.While here, my laptop under the same build as above, having an Intel 530graphics (and a GeForce 950m, non-functional) works again perfectly wellusing 'driver Intel', whereas 'driver modesetting' is absolutely unusable.>>>
