Similar issue here. Opened my 5.0.3 project and it says Nanite and Virtual Shadow Maps won’t run if I don’t enable SM6 in my settings. Without this, all of my textures are ruined and nanite is acting crazy.
Enabling SM6 gave me a loss in performance. Like from getting 80-90FPS in editor in 5.0.3 to getting around 70 in the same scene in 5.1
The real problem is Play in editor
The performance tanks. In 5.0.3 I had 60+ FPS but now hardly 15 FPS
Don’t know what to do. Will use 5.0.3 for now
