I have SP4 i7 256GB 8GB RAM model. I got it 2 days ago. Works good but when I use Maya 2016 (3d software) and select any part of a relatively light and simple model the software freezes for half a minute or more. I can switch to other already open software or interact with windows and continue working but Maya stays froozen and then suddenly unfreezes. Until I select again. Extremelly frustrating as I need to be able to display my work on it. Is it buggy display drivers? What could I do? I am in Europe so can't get refund. I think the hardware is not defective just in Maya2016 somethign odd happens. Do you think future software updates will solve this? Really frustrated. P.S- Btw I have all the latest updates applied.
