Content examples have Lumen and Nanite turned on, Lumen and Nanite were improved from 5.3
My tests were done with these features off, configured for games that need performance
Lumen, Nanite, Mesh Distance Fields, Temporal Super Resolution, Virtual Shadow Map,
Tested with these turned off for both versions and UE5.2 with DX11 outperforms UE5.3 with DX12 by 50% -100%
with any large and realistic environment I bought
Found this explanation from Unreal Source:
“Unreal’s DX12 implementation has been known to be pretty bad, the first version (since 4.9!!!) that actually multithreads it properly is currently expected to be 5.4 and I’m pretty sure it will only be a first pass at it and 5.5 will get it better
it’s kind of insane they went with a single render thread for this long”
