People switching over to an xbox one x simply because of rdr2 being superior on it are absolutely ridiculous! Each to their own, but it is a bit silly, especially when rockstar haven't even commented on a potential 'fix' if there is one.
The ps4 has far more exclusives and even multi platform titles on par with the x, so there are very few reasons to own microsofts console.
I expect the vaseline issue to be resolved but it does remind of the gta4 situation where the ps3 version was quite blurry compared to the 360. Patches weren't as regular back then, but if the community are vocal enough rockstar will fix this. It is sony who are feeding rockstar and not microsoft, so i am sure they are smart enough to pay attention to them.
If this is a case of ensuring that the game is effectively '4k' then i really do not know what to say! In this case a toggle to 1800p will do.
Have more people tried this on the pro pre patch?
