hi lately iv been noticing some studdering in an odd place and its not really a fps loss. best way i can describe it is for example when im flying over some hangers and look at them with the camera they studder as they pass under my aircraft. im pretty shure this just started happening but i dont know why could anyone possibly help out here? thanks

I think you will need to be a bit more specific to get help with this. Is this something that has just started without you changing anything? What setup are you running IL-2 on?

well apparently its part of the slight performance decrease with the AAA ui 1.2

Go ask at the place where you got them please.
