When I first launched after latest patch I got a no discreet video card found. I went in and set the video to what I had been running , restarted and didnt get the error..

I also played Sub for the first time. Well, Im not sure if it just fits my play style, but it is so much eaiser than PHC..  I have not played PHC (the other side ) since patch but Sub was so much easier mostly do to the construct system not needing to build 3 types of plant to cover T1, T2 and aircraft..
