In SP I am getting 40FPS sustained and higher. In MP I do not go above 10FPS. I have done the reinstall, tried multiple servers, and I just cannot pin it down. I am waiting on some sort of update or acknowledgement from DCS that it is a problem. This 2.5.6 has really caused some issues and it baffles me as to this but like a good little boy, I wont convey too much sadness as many will remind me that it is an Open Beta. I have the stable installed and no issues like 2.5.6. Good luck to all of us. :(
