Brien, I just checked out the video card status in preferences and it shows up as the onboard Intel card. I spoke with someone in support last week and they talked me through how to switch to the Nvidia card but I can't recall the process. My understanding was that I would only need to change this one time but obviously something happened to kick me back to the Intel default. Can you let me know how to switch this back to the Nvidia card, hopefully this will alleviate the problem. Thanks
