That's the strange part about it all. - In Arma 2 missions I have to limit my FPS to avoid damage to my graphics card, so that hits a solid 60. - I get this same issue in all DayZ servers, as well as testing the DaiZy Single Player to see if that would be any different, it wasn't. Still struggling for FPS. - Interestingly though, a friend of mine just told me about DayZ Breaking Point, it sounded like fun, so I decided I would give it a go. I've downloaded that, and on the same map (Chernarus) I'm having the same issue I get in the Arma 2 missions, my FPS is too high. It's peaking at around 500-1000 FPS if I'm at the coast looking out to sea, with all the settings turned up to maximum. I haven't managed to get to a city yet, so I'll have to get back to you there, but the coil whine caused by the extremely high frame rate wasn't tolerable, nor was it doing any good for my PC. One thing I have changed is that earlier I had my processor running at 3.3GHz, not 4GHz which I thought, due to the time my heating was stuck on, and the average room temperature in my house was 30-40 degrees, meaning I was struggling to keep my PC cooled at all, never mind with an overclock. Even so, after overclocking up to 4GHz, everything else in Arma 2, Arma 2 OA and all my other expansion packs are working perfectly, including other versions of DayZ like Breaking Point, and DayZ Origins, but for some reason standard DayZ just won't work properly.
