One thing to test to fix the Microstutters is your "Standby List"
Just google for "Intelligent Standby List Cleaner" and u should find several threads + download for the Program.
Windows 10 has some issues (not for all Users) that the Standby List does not get properly cleared and therefore your RAM might running full (which leads to Microstutters cause of File/RAM swapping).
I have the same Issue in Apex Legends and this helped me to mostly resolve any Microstutters.
Your General low FPS is a different Story, in my eyes you should definetly should have higher FPS.
As Aaradorn stated, try use MSI Afterburner and see if your GPU is not able to get a stable high clock..
desti1337 got a reaction from Auno94 in Micro Stuttering and Lower FPS than expected
