Same for me. I tried "escaping" ReSharper a few times over the years (have used it for 10+ years) - but I kept crawling back after a few days or weeks feeling super handicapped without the features.

I also bought new hardware - and noticed no real improvement (something about a fundamental threading problem, I think).

About 6 months ago I was finally fed up and just accepted I would be slower and less productive in some areas for a while without ReSharper, but that it would be OK.

I still miss features from it on a daily basis, but overall I am now quite happy with vanilla VS2019/22 - and never want to go back to the lag-hell that is ReSharper.
