I have a 3 years old computer with an upgraded GPU (GTX560 - 1 year, mid range) and I can play DCS on 3286x1080, window mode near max settings and if I use only one monitor, 1920x1080 and Fullscreen mode I can max almost everything. I have 35/40 average stable FPS.
I have flight mates with even older and must worst computers, some of them notebooks, that can run DCS with average to low settings with smooth FPS. Around 20/25 FPS average.
With so many reports of smooth play on so many kinds of computers I really don't understand how can you guys keep blaming ED for a very complex yet reasonably polished simulator.
Computer and games world is a complex one and is impossible to game makers to cope every problem around like drivers, diferent hardware, etc.
I'm 100% sure that the majoraty of problems reported here can be solved with the right tuning on same computer on this same game.
