First of all thank you all for the warm welcome, this is my first post so please be gentle. (that didn't come out right, did it?) Anyway I am in my early 50's and just want to learn from you young studs out there, so please be patient. I recently installed DCS World, FC3, and A10c which to my surprise run fairly well considering my outdated system. I get aprox. 30 fps. on the ground with all aircrafts, and in the air 45+ give or take depending how hectic things get up there. However there is one thing that really has me puzzled, with the SU27 the fps count drops and even more when I turn on cockpit lights, is this normal? :dunno:
