@rjsict My issue was remedied by lowering my AA, I had it full to the right. It is now at 4X. The changelog mentioned "added new glass reflections to PFDs & MFD screens, adjusted panel textures, etc", These new items put more of a strain to my GPU, thus causing my stutters. I noticed you use a 4K monitor setup with no AA, Of course your situation will vary as every setup is not the same.
I hope you get your issues resolved.
