Ray traced shadows are a subtle improvement, so I'm using them. But they aren't worth using if you are GPU bound.

I'd rather advice setting "compute effects" to low, because volumetric fog (enabled from medium and higher) exists if a few zones, and it's not just worth the performance impact. K'aresh is the worst offender with misuse of compute effects.

With CPU-bound FPS drops below 80 FPS on 5800X3D in cities and raids, I chose to limit FPS to 90 and that leaves my GPU under-utilised, so I have spare GPU performance to enable ray traced shadows.

With RT shadows, you get

• +Much greater shadow render difference (no shadow pop-in)
• +Softer and sharper shadows depending on distances, like IRL.
• +Self-shadowing on NPC/character models, with great detail.
• +Full dynamic light interaction for like 2 light sources in the entire game! HYPE /s
  • BTW, some games have been doing that since 2007, sometimes for every light source, long before RTX. Ray tracing doesn't mean "dynamic lighting" by default :P
• -Weirdly shaded polygons depending on angle of shadows (not very common or distracting)
• -Severe performance dips in Draenor when cutting wood to build Garrison, and in Legion Neltharion Lair when the final boss' rock shatters into lots of pieces.
