There could be something wrong with the sim. Based on your subjective opinion, you could write it up as a discrepancy (see 14 CFR 60.25). Anyone can write up the sim. There are automatic and/or manual QTG tests that can be performed by the sponsor to determine if the visuals or motion cueing is out of tolerance. All it takes is one parameter or more to be out of tolerance and the sim may not "pass" the tests.
