Newbie question

Hi there, i am new to all this but i have a problem that i am hoping someone here might be able to help me with.
I recently bought combat flight sim 2 and installe it on my PC but it doesnt seem to run smoothly, it is very jerky which is a pain, my pc fits all the system requirements so please help me, i love these games and want to be able to play it to its maximum.
Thanks in advance
