I think most of the dislikes are becuase video has a lot of stutter. Tho don't get me wrong scenes all scenes look great however I didn't like one with the F-15 in current Caucaus map since it looks like trash.
Everything else is great.
So if you are plaining to make videos "professionaly" I would advise to upgrade your PC if you want to do it just for fun this is more then enough.
