Every game I have runs just as well under 11 as it did under 10--I mean, to be expected, as Win11 is Win10 with a few cosmetic changes and an upgrade on the baseline security requirements. I had all of the W11 requirements running Win10, fully supported, and the only difference in that regard is that W11 mandates them while Win10 supports them but does not require them.
I've had TPM 2.0 since I bought my last mboard two years ago--and the rest of them I was using for years before that.
But Win10 has at least 3.5 years of life ahead of it, fully supported, for those who balk at the slightly increased security baseline of Win11. Win11 hasn't actually been released for the markets--that won't happen until October--what everyone is running are the current beta versions available through the Insider's group. Current beta version is 22000.100, for those who are interested.
