I didn't know Ark even had RT support!
Ark's shonky reflections were exactly what I was thinking of - the wings of any flyer in ark reflect off water bodies far away in a really weird-ass way. Raytracing could fix that.
I have not played Ark. I have, however, played Control. I had to right? best looking RT game out there etc. And it is, in ways. Some of it really is amazing. However, you enter a room and a big black swirl flies about and stuff starts flying and then some boss thing comes out and you see it.. Grit. Grain. And it is really, really distracting.
So as much as I really enjoyed looking at the chick in the reflections and having a good look at it all like you would when you photocopy your arse at the work do, that was about all it was for me. It was distracting, and not in a good way.
It seems to be something to do with the shadows, not the reflections. Maybe it is because Turing really isn't good enough? maybe it is something else I really don't know. But I would walk into a sun lit room in Metro, go "wow!" and then notice something was clearly very blocky or pixelated. It was like I say, you are robbing Peter to pay Paul.
It may well get fixed, but like I said it ain't worth no £1300, or in my case of ahem, "winning the lottery" and spunking £1800 on a GPU?. Put it that way, if it were my money I would be a total fool. It would be even more not worth it then.
For many moons I did game at 4k. From two Titan Black (and then 3) to the death of SLi and Crossfire (CF Fury X). And it was amazing, but I got sick of paying the price. So, instead I hopped to a Titan XP, downgraded my monitor back to 1440p (because a lot of software I used didn't like 4k so the menus were not legible) and whenever the Titan XP still had the balls (like FO4) I would just use DSR to up the res to 4k, sorta kinda. Which worked very well, jaggy free gaming for all.
Maybe at some point I will try the games I mentioned with DSR and RTX and see if the 4k slideshow takes away the issue? I would doubt it. It's definitely RT based, whatever the heck it is. It doesn't happen with it off.
