My setup is PS4 Pro, 43" 1080p non hdr tv, boost off, supersampling off, disc copy and version 1.02.
RDR2 at times looks great in various locations and with smooth frame rates in Valentine and Saint-Denis.
However there is also lots of times with various amounts of blur and out of focus look.
This more than 4K checkerboarding problems as all systems are experiencing blur issues.
I believe this game is presented as intended. R* went big for realism and the graphic effects are part of that.
The problem is that R* may think it is pretty and Oscar worthy while lots of squinting gamers hate the look
Many gamers, like myself, hate anything that adds blur and washed out colors to a game.
The fix is to provide setting options to disable effects like dof, camera blur , and god rays.
