I get the same..I think it may be due to the density of the smoke. My fps dont drop much in cockpit view with the flares but the MLRS and mass arty strikes are a killer. I just make my own missions and dont use the MLRS or large arty strikes. But I dont have a super PC either. I still get a solid 30+- fps with a single core intel 3.4 extreme,2gigs ram and a nvidia 8400gs 512 card.I have my options on med and did edit some of the other usual options in then LUA. either way i just deal with it because this is an excellent sim by all means. nice work ED. I am a rotorhead and i am still sportin wood over this.....
