You can also achieve nearly the same level of performance by adding exclusions to Windows defender. I typically exclude the game process as I still would want folders scanned when updates / downloads are running. There's a noticable improvement to load times, streaming texture latency, and CPU utilisation.
I don't believe ReFS is contributing so much to the performance improvements seen when using Dev Drives. Removing storage filters from volumes can go a long way.
According to some benchmarking removing the storage filters offers a mild boost when compared to adding an exclusion and you don't have the benefit of some AV protection when other processes are accessing the volume like steam etc.

The file system filter is still queried using exclusions. Eliminating all file system filters yields a faster read/write.
