I don't have this problem either and I probably have one of the oldest gpu around- gtx 680 4gb, its supports up to dx12.
This is a new pc I built that's running windows 11 beta, just used my old gpu cause of prices at the moment.. Ill get a new gpu eventually. I'm going to have to say this a software or driver problem
Windows 7 supports DX11 but only partially supports DX11.1
i5 - 11400
