When I try to play Dayz Epoch, I get low fps. I can play any other dayz mods with at least 25-40 fps. But in any epoch server, The max fps I get is 20. This might be high ping, I try to join low ping servers, but Dayz Commander has difficulty sometimes giving accurate ping. I have messed with settings, arma2oa.cfg, and launch parameters to get better performance but it does not help. Does anyone know how to fix?
