No problems here. Its most likely a problem with your control setup, or you just need practice. The 777 handles wonderfully for me, that is when it is trimmed properly. Note that you can activate a "FBW" bug to see what speed the airplane is trimmed for, and you'll want your trimming to be precise in order for the airplane to behave properly. This is the only "quirk" of the pmdg 777 and has been discussed before. Keep in mind that its the European and Asian carriers that use the high level of automation all the time due to the zero to hero flight programs over there. On US carriers with a clear day and a manageable workload, its common to manually fly below 18000 feet, and even turn the FDs off(oh heaven forbid ). Good luck and enjoy flying!
