Thank you for your advice，i have AMD VII,but in other computers,the gtx titan supported in Big Sur in the other i7 computer is working perfect，and i check in the Internet，gtx titan 6G Should be supported in Big Sur，it's the first titan for nvidia 7 series,so I am very confused now ：（ Could it be the acpi problem？i use all ur ssdt for the acpiYes - I chose not to map those 3 USB 2.0 ports so I could remain under the 15 port limit. It is possible to create a virtual device and map the USB 2.0 ports to that so you can remain under 15 ports per controller but it gets messy and I didn't need those USB 2.0 anyway.
But I'm almost 100% certain that your problem is the GTX Titan - it is not supported in Big Sur at all and would definitely cause issues like this. Also the experience without a supported GPU will be terrible. You should consider changing to a supported AMD GPU or if you really need the Nvidia GPU in a different OS then run both AMD and Nvidia, but disable the Nvidia GPU in MacOS.
