Yes it was a fairly big difference between 1440P with 4K DSR and actual 4K. A lot more level of detail. Like I could make out details on characters clothing from a lot further off. Or see details in their faces from far away.
With my old 1440p monitor I selected 3840x2160 in the Witcher 3 graphics settings.
The issue I had was higher GPU utilization with 4K DSR then actual 4K. as much as 20% difference. The higher utilization gave me a higher more consistent frame rate.
Wow... How come I didn't see any difference.. Was it because I expected more and blinded to some visual improvement..I already returned my 4k monitor.. I feel like buying a new 4k monitor and do a more thorough analysis.

What 4K monitor did you buy? Some monitors are great right out of the box, others require a lot of adjustments to make them really shine.
Its possible your expectations were really high. I mean, it wasn't like it was a whole new gaming experience for me. But I never really thought that going into it. My 1440P monitor was a really great monitor as well. So it wasn't like I was going from a low end 1440p to a high end 4K. At 4K I have to stop and admire the extra detail. If I am actually playing the game, battling, driving fast, running, etc. then I'm to busy to really notice any difference between 2K and 4K. Again there is definitely an obvious difference for me it just depends if I am stopping to admire it or actually playing the game.

It was U28D590D...
To clarify you meant 4k DSR vs 4k Native right?
From regular 1080p to 3k/4k DSR its miles better. But when I looked at 4k monitor it was identical to the 4k DSR on my old monitor
.. Another question, did you have to adjust the mouse higher to cope with 4k monitor?

Correct, 2560X1440 monitor with 4K DSR enabled vs actual 3840X2160P with NO DSR of any kind.
No I didn't have to adjust the mouse at all.

Hmm somehow I had to with DSR enabled.. So you're saying you didn't adjust mouse settings for both instances?

Well I had to adjust the mouse for DSR... For example, the mouse needs to be adjusted higher for DSR... Wait I think I know what it is.. It's the menu in games where I had problem with the mouse.

I have a 1080p hooked up to the HDMI port on my Titan X and I still use 4K DSR on the 1080p tv. It works fairly well.

I see. Have you played around with DSR? Meaning for 1080p, I played games at 2x, 3x,4x DSR. I notice the biggest improvement is from 1080p(2millions pixels) to 1520p(around 4 million) with the biggest Visual improvement, even more than from 4million pixels to 4k(8 million pixels).
Just wondering if you notice anything like that.

A little bit, prior to Titan X SLI I had 980 SLI. Which wasn't really capable of 4K. At least not to the way I liked. I gamed at 1440p DSR on my 1080p tv. It was a nice visual improvement for sure. Interestingly enough with an actual 4K monitor now the DSR options disappear from the Nvidia control panel. When I swap my monitor over to the 1080p tv the DSR options re-appear. From what I understand 4K monitors disable DSR in the drivers. Which is strange because when I had a 1440p monitor I had the option for 5K DSR. Might be fun to play some older games at 5K DSR. So I wish that option would come back for 4K monitors.

It could be the SLI. I've heard some people had to create custom resolution to make DSR appear again. I'm not exactly sure about this. Just hearing things.
Just wondering and it might be personal for me to ask. But why did you buy Titan X instead of gtx 980 TI unless you bought them before it came out. I also thought the same thing about gtx 980 sli is not going to be enough for 4k.
4k from my experience takes around 3x performance hit of a 1080p. So if 980 is enough for 1080p, 3x 980 at least will power 4k not to mention about sli scaling. So I thought I needed at least Titan x sli or gtx 980 ti sli to be enough for 4k.
970 for 1080p, I hear it a lot, I still disagree gtx 970 is best bang for the box but it's nowhere near enough for 1080p unless you disable AA on dragon age inquisition, not enough for gta 5 max setting for sure even without AA, it's not as optimized as dragon age or witcher 3. And I don't think its enough for witcher 3 as well. 970 I'd say barely enough for 1080p even without AA

Its on purpose by Nivida, they don't allow the DSR option with a 4K monitor as they feel trying to move above 4K wouldn't provide a good experience since it would be beyond 99.999 percent of all configurations. I was told this in the geforce forums.
My wife surprised me with the Titans as a present, so it wasn't something I had picked out and it was before the release of the 980 Ti's. I am happy with them and I like the 12gb frame buffer as I have plenty of games i'm playing now that exceed 6gb. So I didn't feel the need to send them back. If both the 980Ti and Titan X were out at the same time and I was shopping for myself I would probably have just got the 980Ti.

I just got a 60' HDMI cable to run from my PC to my bedroom. I have a 32" 720p tv in there and I thought it might be fun to game from bed on occasion. With DSR on the 720P tv my max option was something like 2250x1540. Looked pretty bad compared to my 4K monitor. Mainly I just wanted to see if I could get a signal through a 60' HDMI cable and it worked great. Now I just need to upgrade that tv to at least 1080p.

Well friend I just got my own 4k monitor and gtx 980 ti sli... Gpu utilization... I experience the Same thing.. It's not our fault I guess.. They need to optimize the game and the drivers to get gpu usage to 99%. It seems to happen in all games 4k SLI.. But at certain scenes it's 99% usage. It seems like it's the scenes that matter. I tried them on Dragon age, witchers 3 and gta 5.
PS: lordkaless, yes I see the difference now on 4k :) ... cant believe i couldnt see the difference the first time...

Witcher 3 is the only game I have experience odd utilization since going from 4K DSR to native 4K. All other games like GTA V have had excellent utilization. Glad it is working out for you

Well yes it seems witcher seem to have most problems with gpu usage issue.. That's the first thing I noticed. Whereas in my other 2 games, it didn't occur as much. And the usage for witcher 3 were jumping up and down between 50-70%. And I was standing still in the room that was in the castle before meeting emperor emyr

Witcher 3 has GPU usage issue, in sli, But it is not that bad. Its all about the stupid consolls Why do you think batman arkham knight launch width 30 fps cap and looks crap, Allmost no graphics settings, It is because of consols G-sync Fixed BOTH Tearing and stuttering to 100% I gott rog swift my own :) there will be a new Rog swift 1440P 144hz IPS soon aswell, So a uppgrade there + I would never go 4K it is a waist of cash width no G-sync atleast!! Just go rog swift, Then DSR= 144hz 4K + G-sync :) and there will be plenty 4K Gsync monitors soon.! 60hz atm is just no go

Some people are different. I prefer maximum visuals. I don't play shooting games, so I don't see the usefulness in over 60fps. It's not a waste of cash to me when you're maxing out GTA 5 on 4k with 70-120 fps. As for G sync, yes it's nice however, adaptive v sync does the job as well if your games are over 60 fps. It'll never look as good as 4k monitor. Competitively I play dota 2, and the rest is to enjoy the view in games.

I am good with 60fps, I can't tell the different above that on 144hz monitors I have seen. I can't tell the difference between a solid 40fps and 60fps. Now if it fluctuates a lot I can tell the difference.

I can tell between 40-60 however I'd like to try from 60-144.. But as he mentioned he said he wanted to use ROG swift 1440p 4k DSR, to get 144fps on 4k is not possible on witcher 3 or new games to come bur it might be possible for older games that have good SLI drivers and optimized games, and I'm talking about 4-way SLI gtx 980 ti or Titans X here. So I don't know if that's called saving money.

Try checking your setting again, for some reason my resolution wasn't set to full screen.. Maybe because of alt tabbing, after using full screen resolution, it seems to give me higher fps.
