I am getting 59fps most all the time. When I get around an airfield my FR drops to about 40 then goes right up to 59 again. Sometimes it will drop and hang around 40 then go back up. When this happens it starts to stutter. I am running hires textures. 1024 size and a res of 1920x1200. Also my ingame memory says 512 available, 156m used. Also take a FR hit around the black smoke. If my system cant handle it with the settings I have. What parts do I need to update? I just had it built about 8months ago. Not affraid to make it better though.
