1)It is not the helo itself which causes the problem.
2) the problem does not result in stuttering.
The problem is caused by the design of the ship which results in pauses ( there are other sceneries as bad which I cannot mention here ).
This can result in the user thinking it's their machine when in fact it's the designers fault.
Luckily it is easy in this case to remove certain textures like the static helos from the decks and other little things to improve the draw issues.
This trend of designing sceneries which do not function correctly has been getting worse lately!!
To Aerosoft's credit they were at least honest enough to admit it from the beginning.
I still wonder though why a company would set out to sell a product which they know causes problems no matter what the machine.
For the money
