Maybe we should start making short videos and compare these things.
I'll start with this one:
Object: Shadows and details of anti-climb guards on barriers
Versions: 1.21 and 1.23
Location: Drop Point at Palm View Street, near by the Afterlife
Settings:
1080p, everything maxed out except Chromatic Aberration, no DLSS
rtx3090 ; 5950x ; 4x8gb ddr4 3600 ; x570, stock PBO, XMP enabled
OC: Precision X1 ; memory clock +248, core clock +50, power target 119%
FPS cap: 360
Mods:
Video1: No mods
Video 2: [Streaming] DistanceBoost = 45.000000
Videos:
1)
1.21: -> YouTube
2)
1.23: ->YouTube
Result:
There doesn't seem to be a difference in the speed of the shadows on those barriers. It shows 10 FPS more, which might be the result of lower GPU temps and higher clock speed.
