Anyone else having performance problems with the 777?

A lot of people have claimed that performance was better with the 777 than the 737. Honestly, I am having all sorts of issues with the 777 and I think the performance pales in comparison to the 737. I just had a three hour flight that CTD as I was on approach to land. Frequently when I go to move my camera view around the cockpit the screen freezes temporarily. When I switch to outside views it takes longer for the plane to fully appear than it does with the 737. I've made many flights with the 737 without any of these issues, so I am not sure what the problem could be. These stutters really break the immersion and I found myself flying the 737 again.
