I have same gpu as you. I fly GA and don’t really have any issues, pretty smooth and stable. Not as rock solid as xplane but xplane does not have the visuals of MSFS. I don’t do voodoo fixes just a few settings required and off you go. Been at this for years and MSFS has taken many many searches and a long time to understand, but now it’s been stable for weeks.
All that said though some have expectations beyond the current capabilities of today’s systems. This is not their fault, its more the people in the know misleading them.
VR allows people to “be there” but at the cost of blurry visuals. For some - like me - that’s well worth the sacrifice, for others they can’t live with not seeing crisp clear images.
