I have a 4th gen i7 , 4770 with 16 GB RAM and Gigabyte GTX 960, 2GB. I had decent frame rates with DCS 1.5.8 and 2.2 with a mix of medium and high settings but with 2.5 I was hardly managing 16 tp 25 fps at low settings. Just yesterday I bought a used Gigabyte GTX 970 G1 gaming card and applied the setting suggested on page 3 of this thread. Now I am getting 40 to 60 fps from inside the cockpit but it drops to around 30fps with outside views. Is that fine or I need to further fine tune something?
