Performance wise? Yes, however some of it is being tested. Nanite itself is relatively stable, but with Foliage and WPO? Starts to be a bit unstable, but they are both beta features while getting Nanite to where Tessellation was before. Now that it’s there, it’s great but also is still in progress so we could be running into that issue.
There are a myriad of driver issues that can occur to cause these crashes specifically as well, most happening only on DX12 + SM6.
