Tim Sweeney on Unreal Engine 5 Optimization Issues: “The main cause is order of development” [“Ideally, optimization should begin early—before full content build-out.”]

My issue with Unreal Engine 5 is pretty much exclusively Lumen.

Developers turn it on and call it a day. No baked lighting. No reflection probes. Just blurry reflections and blurry shadows with FSR on top for extra blurriness.

It runs and looks like absolute ass and I simply stopped buying UE5 games that use it.

I haven’t played any game that uses Lumen. At least that I know of. Can you give me an example?

Pretty much every UE5 game I have played so far has it, with very few providing fallbacks to old school lighting.

To list some of the worst offenders I can remember right now:

Lords of the Fallen (2023)
Remnant II
Talos Principle 2 and Talos Principle Reawakened
Wuchang: Fallen Feathers
Supraworld

ah. Dodged all of those 😅

LiveLM

I looooove Talos Principle but my hardware is getting long in the tooth and 2 runs so blurry (and not well enough to compensate) that I gave up on buying the 1 Remaster, even though I really wanted to play the new bonus chapter…
