I started playing raceroom yesterday after I decided to buy DTM 14. Once I got it all installed,I fired it up. It was ridiculously laggy. I tried everything to fix as I have a system that should run it no problem. For a hour of frustration I changed graphics settings and tried anything I found online. Then I decided to try in windowed mode (not full screen). It stayed full screen anyway but fixed the problem. Now It runs great. So you guys might wanna look into that. My system specs are Intel i5-4460, 8gb ram, AMD R7 370, windows 10 Anyway I think this game is really good and I've had such a great time playing the DTM '14 that I bought ADAC 2014 as well. Keep up the great work.
Heard about that a couple times now and seems to be connected to Win10 and drivers. If there's anything the team can do to improve on the issue they will, but it might just be down to MS to provide the necessary fixes.
