That’s a tricky question
I’m going to say NO, if you feel you could have all settings at Ultra in VR.
I have a 4080 and in VR it still feels like I need more. Please know that I am content with the outcome because there is nothing more I can do but get a 4090. MSFS is not at the point where I want to put even more money into it.
Yesterday I flew, and it was amazing, and it thrilled me in the Sim. However, that changes from day to day in the Sim because of performance.
I don’t regret getting the 4080 (FE) and I can only hope the Sim gets better for VR in time.
Good Luck
