GPU Lightmass Test Unreal Engine 5 RTX 3090

Trees created with @SpeedTree and assets from @Quixel Megascans
No Nanite just high quality meshes and some 8k textures.
Light is HDR and volumetric fog.

Testing Baking with GPU lightmass with RTX 3090 entire scene took only 10min production quality and high settings.
Pros using GPU Baking are more accurate GI and fast bake, AO settings in PP, 120fps.
Cons are you need RTX for it to work.

Pros Using Lumen no RTX are no need to UVMap assets, no need of reflection probes, no mass importance volume, no more setting lightmaps resolution, better reflections, everything is full dynamic.
Cons using Lumen no RTX with same scene are getting 40fps, cannot control AO, GI is not that great.
