Situation is that: multiple monitors (multiple video cards). Open editor at one monitor = 120FPS. Open “Editor Preference” window on another monitor = 40FPS. Open third window on another monitor = 20FPS. Told you about it at UDN about year ago…
So, on production workstation it is force you to use one little window. All Niagra, Chaos, and other improvements are great, really, but if you lock people to work at 20 FPS all of those improvements negated.
