Just bought DTM today with a view to getting into both it and R3E. I'm on an iMac with a 4gb 780m (mobile) which doesn't support Nvidia Surround 2D but in Assetto Corsa I was able to run triples in windowed mode 7680x1440 and lower no problem. Is this possible in DTM/R3E. Going from triples to a single screen really loses the immersion I had with AC. Can I create a custom res or is there any other way to get it to work. Cheers.
