I compiled the current version of UE5 from source (Downloaded on 27.11.2021), and noticed that the performance of lumen has gotten considerably worse. (Comparison done at same settings/location etc. Will investigate further tomorrow.)
EA2 (FPS):
57
71
53
Current UE5 from Github (FPS):
43
61
41
Hardware used:
CPU: Ryzen 3700X
GPU: RX 6900 XT
That said, there are some visual improvements/changes.
- less “noise” from emissive reflections
- GI from subsurface materials is now stronger.
- Light sources in general seem to be stronger? in comparison to EA2. (there sometimes is more “bouncelight” in direct comparison.)
Then there is this “Endless loop” of lumen getting brighter for no good reason (issue wasnt there in EA2 (ignore the broken UI-stuff, something got removed and UMG decided to stop working.)):
