I don't know if I am crazy or not but I just tried the mod (updated version) "WithDynGPUFreq" I played for 2hours docked and I followed this video for settings :
Youtube Vid
It's litteraly at least ps4 version now
the game is so clean with shadow, light effects, rain effects and all and the framerate still the same, maybe even better. Quality of details is now amazing and the drawing distance is way better.
I play without any overclock!!
My mods work but i realised one side effect, there is less cars.
Thank you so much this mod is perfect! I hope you will update for the new game update soon and improve the mod again!
I attach my settings ( in french sorry)
