I might release my quality settings… but ive made myself some low medium and high settings for nanite, lumen and virtual shadow maps… and im shocked that i got my detailed city with lots of detailed nanite meshes running at 90 fps even with my RVT in the scene. highest settings i never get below 60 fps … even with tesselation enabled.
The trick to using nanite, lumen, virtual shadow maps, and Run Time Virtual textures is the CVARS console commands and the best way to test them is device profiles.
And im nto even done yet… i feel like i can get this up to 100 fps. Its currently 4k rendered at 1920x1080 with TSAA upscaling.
World Position offset materials need to be handled with care… disabling them at a distance or telling them not to modify the virtual shadow map all together with realtime updates.
