I have recently built a high end PC and have installed steam and some games etc. all the drivers are up-to-date, and for the first day gaming i spent on Arma 3 Exile and i was getting 60fps+ which was fantastic! but then a couple days later i realised i was not getting the same fps, and for the the last week or so i cannot get anything higher than 13fps! I have spent over a grand on this pc and do not want to have to deal with these kind of frame rates, i have been trying to find a solution and i am at my last resort here, i need help guys please can i do anything!?!
