>>105854814 (OP)>Are there primary differences between Windows 11 and Windows 10?One notable difference is that Windows 11 can make proper use of CPUs with >64 threads
Before win11, a single process was limited to using 64 logical CPUs, and getting above this limit required a conscious effort from the software developer. Most didn't bother. And even if they did, scheduling still wouldn't work optimally.

BTW that 64 limit was the best case scenario. If the total number of CPU threads wasn't divisible by 64, it would be even less. For example, if your processor has 96 CPU threads, each process would be limited to using just 48 logical CPUs, because each processor group has to have an equal number of logical CPUs (but no larger than 64).
