When you are looking at RT shadows then you will know it.

  • I love having them on.  I don't miss the jaggy shadows from 2020.

    On equals pin sharp shadows in the cockpit, off equals soft and aliased shadows.  You must be able to see a difference!

    It is the main culprit on the VRAM BUG. Thus, I have had to turn it off.

I used to have them enabled since mainly was flying GA but I recently bought the Fenix and it was often crippling performance on my 7800x3D and 3080ti system.  64 Gb of DDR5 wasnt helping.  Started going through the various settings and knew it was one of the gpu intensive settings.  RT Shadows gave me at least a Gb of reduced vram use which really did help.  Might keep it all all the time now and increase the shadow resolution in the UserOpt.cfg file

Not entirely true.

The part about ray traced shadows off is true - they are all very soft.

However, ray traced shadows on can have both sharp and soft shadows depending on the light source how far the object casting the shadow is. That's what makes it better - it's more realistic.

You gotta luv Ray Traced  shadows and the fps is small IMO.

For my eyes, the visual difference is small and the fps cost is between 5 and 10 per cent.

I can see the difference but, a quick check shows about 6-7 fps loss, depending on scenario. I'm not concentrating on the cockpit shadows ...I like looking out the window. 😉

Obviously - it is the sharp shadows I was describing as the stark difference between on/off. 🫣

I wonder if people who are using RT shadows have tried 'Shadows Size 6144' in the UserConfig instead.

Nice crisp shadows and no perceptible performance hit, unlike with RT shadows.  It makes RT in this case totally unnecessary.

I don't understand why Asobo aren't advising this.  It seems like they don't know their own sim sometimes as they have never mentioned it as far as I know.

Yep. My post on Page 1. Nice sharp shadows, zero performance hit.

Sorry.  Was speed reading this morning as I had to go out.

Yes it does.  Just that I noticed it wasn't significantly better at 4k, and it introduced just the slightest performance hit at 8192, so I just dialled it back a bit. 
This was with my old GTX1080 though, probably my newer 4080 would handle it.

Meanwhile, 4096 was still just a bit softer on the shadows, that is why I settles for 6144 halfway in between. 
This was probably 2 or 3 years ago in MSFS2020.  I haven't changed it since, I just carried it over into the 2024 UserConfig.  All good!

When turned OFF performance is perfect.
