Difference between DSR high res and native

[Dakpilot]

Just wondering if anyone has experimented with using DSR to get higher resolution and then upgraded to a high res monitor and could explain the quality and performance difference when using DSR compared to high native monitor resolution 

 

And what performance if anyone is using a GTX980 with 4k resolution and their experience

I had a Acer B286HK and got around 40-60 fps on ultra with the 980. Spotting was great but I really didn't feel like 4K gaming was quite there yet. Also the monitor had some ghosting issues. I switched to a ROG Swift 1440p 144hz GSync monitor and have no intentions of going back to 4K. I've had 144hz monitors in the past but G-Sync is amazing. DSR is great too but doesn't trump pure resolution in picture quality, it's just that smooth movement trumps all.

Just got the ROG Swift a couple of days ago and definately better performance than using DSR on my GTX 970. I am likely biased since I upgraded from a 1280X1024 4:3 monitor.

In a moment of pure madness (was in a $1200 price reduction sale!!) I bought a 49" 100Hz 4k TV to use as a monitor, will see how it deals with upscaling, has a 4 core chip, before getting a GTX980 in an upcoming "bargain deal"

I can't say I agree,

 

Will never return to the 1440p IPS 120 hz after using this 60hz 2160p... Aside from the much better image quality, screen tearing is hardly noticeable without vsync on this panel and I can maintain 60 FPS min. with the highest settings offered, including AA, so tearing can also be eliminated completely. Incredibly smooth and no ghosting.  We run very different hardware, so a direct comparison is difficult. However, after some first-hand experience, I frankly do not understand the benefit of an added scalar on a 144 hz monitor that incurs an additional input latency penalty. I've always found variable input latency to be more of an issue than screen tearing on any hardware.  Anyways, I'm going off topic into an area that is not adequately explained by anyone, including the engineers involved in the implementation.  

 

As someone else said, no form of super-sampling is comparable to native resolution and does seem to include some additional performance penalty over native resolution.

 

 

 

Dakpilot, Though I have no point of reference, you may find that upscaling isn't necessary with some moderate settings adjustments. Depends on the arch, driver and engine, but sometimes it's surprising how well things can run when pushing an additional >6 MP. That said, some of the TV scalars have pretty nice up-scaling artifact-reduction implementations, so you might find a very happy medium with your current hardware below non-native.  Best of luck

My screen will hopefully be arriving in a couple of days, so will report on my findings, I think I really need HDMI 2 on the card to be able to output 3820 X 2160 @ 60hz which the TV has, so I may have to get a GTX970 or 980 for that connectivity...am feeling a tiny bit of buyers remorse  It is also 3D capable so I will have to have a look at that feature as well,  so hopefully when it arrives it will make me happy

Did you verify the TV supports full chroma with hdmi 2.0 there has been some issues with many early 4k/60 tv's.

You will be very disappointed if it doesn't support 4:4:4

 

Yes you will need a 980 unless the TV has DP1.2

Thanks, checked for full 4 4 4 chroma through HDMI 2 @ 3840 x 2160 60Hz, it only has HDMI 2 no display port so looks like GTX970 or 980 to get full UHD @ 60Hz

 

and it is on the list as confirmed by multiple users  thanks for the link I spent a lot of time verifying this point but never read that article

I'm planning on a 4K monitor too. Interested to hear anyone's experience with this.

My experience with DSR (4x on a 1080p display) is that it doesn't greatly enhance the picture and is quite costly in performance.
