I'm using Windows on 3 different gaming PCs with a 3070 (PM 5.5c), 5700XT (lolminer) and 1660Super (PM 5.5c). No issues with stability, shares...nothing. I'd post an image of my pool results, but I'm not sure how on this site:

stale and invalid look great...but 13mins not long.
Looking at the results from randey it shows that higher Hashrates solves shares faster, the RTX3070 with 61MH have 55 valid shares and it beats others with lower hashrates, makes lot of sense I believe 🤔
