March 8, 20251 yr 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 Chris Ibbotson AMD Ryzen 7 7800x3D / MSI AMD MPG x670E Carbon Motherboard / Gigabyte GeForce RTX 5090 Gaming OC 32GB GDDR7 PCI-Express Graphics Card / Corsair DOMINATOR Titanium RGB Grey 64GB 6000MHz AMD EXPO DDR5 / NZXT C1200 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 1200 Watts - 80 PLUS Gold / 48” UltraGear™ UHD 4K OLED Gaming Monitor / 40" Philips 4K LED Monitor / Honeycomb Alpha Yoke / Honeycomb Bravo Throttle Quadrant / WinWing Orion Rudder Pedals c/w dampener / WinWing Ursa Minor Airline Joystick / WinWing Airbus MCDU
March 8, 20251 yr I love having them on.

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. dd
March 9, 20251 yr For my eyes, the visual difference is small and the fps cost is between 5 and 10 per cent. 5800X3D, RTX4070, 600 Watt, one or two 1440p 32" screens, 64 GB RAM, 4 TB PCle 3 NVMe, Warthog throttle, VKB NXT EVO stick, Honeycomb Alpha yoke, CH quad, 3 Logitech panels, 2 StreamDecks, Desktop Aviator Trim Panel.

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. 😉 i7-13700KF @ 5.3GHz 32.0GB DDR5 @ 5600 RTX 3080 65" LG OLED @ 4k

Obviously - it is the sharp shadows I was describing as the stark difference between on/off. 🫣 CPU Ryzen 7800X 3D RAM 32GB Corsair VENGEANCE DDR5 6000MHz GPU GEFORCE RTX 4090 Monitor AOC AGON AG352UCG UltraWide G-Sync @ 3440x1440 Internal Storage 1TB NVMe PCIe SSD External Storage Three 4Tb HDs
March 9, 20251 yr The water reflections need to be ray traced or path traced. At the moment it is just horrible (both sims). http://youtube.com/c/Greazer
March 9, 20251 yr 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. Rob (but call me Bob or Rob, I don't mind).

March 9, 20251 yr 1 hour ago, Reader said: 8192 also works very well. 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! Rob (but call me Bob or Rob, I don't mind).
