Post your DSR and VSR sreenshots here

Both are great little features, (DSR/VSR). But once you start going crazy with the res, it's a way of letting you know just how poorly equipped you are to deal with it. Tried bf4 at 3840x2400, sp campaign from my earlier shots, settings maxed. Dont think i seen it over 50fps.:o

Makes you want to spend more.

Well at least you apologised, so that's something. Well done :)

And I did say on the first page to post how you like (to try and get the thread to do what I wanted) but then you get all rude and finally started calling people nbots, so pretty childish really.

Maybe better if you didn't get so heated and chilled a bit. Insults are uncalled for.



Triss, you should join us on a Wednesday night on TS and BF4... Some real stick given to either brand in the jovial sense it is meant. Nobody cares what GPU his fellow gamers are using and we all want to play and have fun. Sadly, some here don't work that way and end up getting personal and all for the sake of what GPU they have.... A real shame really.

Shouldn't talk about yourself like that tbh you one the worst around here for it.. Don't try playing Mr nice guy won't work.

Add another gfx card :)

Don't worry, New faster cards are on the horizon, I am sure some upgrading will be done soon.

Funny how he thought Martini is an nbot just because he disagreed with him, kind of sums Shanks up.

What makes you think I was talking about him? Others also jumped on me... :D
And FYI I have known mart to own an AMD GPU for long time know he posted this couple times on this forum.
 
Another resampled image.

You can clearly see the downsampling doing a good job.

yes, but after the down-sampling sharpening is applied. This is why the amount of sharpening is user selectable form the Nvidia control panel.

Yes i have seen some screen shots where users have set the sharpening to low and it does look really blurry, but if it was not for the 13-tap gaussian filter making things softer still, less sharpening would be needed.
 
The default setting works pretty well for me, any real change in either direction makes text look slightly to badly distorted.
 
After playing around a bit with VSR, I love it. Running 3200 x 1800 on my 27" 1440p. Games look great with it on and in some cases, reduced ui size I find is better. Shame AMD were slow to release it. Thanks Nvidia for starting it off :)
 
Is it normal on my 1080p 120hz monitor that i can only go up to 2560x1440 or should i have an even higher res?
i know at the above mentioned res it plays at 100hz

Any method of downsampling will require an additional step of processing. Really bad linear techniques will leave ugly aliasing artifacts, anything like bicubic, Lanczos, spline interpolation etc resulted in reduced high frequencies and soft edges (although some advanced algorithms try to preserve such feature). Sharpening is required to bring that back.

A Gaussian filter is normally used for purposely removing high frequency artifacts like noise so obviously reduced edge sharpness when used for downsampling.

When downsampling the goal is to remove the artifacts and pixelation caused by aliasing but preserve edge sharpness. To maintain the latter sharpening has to be applied post downsampling.

Now that i have read the review i have just posted, its seem that Gaussian blur filter is whats been adjusted to the change the sharpness, the more Gaussian blur filter is applied the less sharp the image.

AMD uses other than Nvidia, for aggregating the individual images a simple bilinear filter, while Nvidia DSR implementation uses a configurable Gaussian Blur filter.The latter has the advantage of being able to fight flickering better but automatically loses the picture a little sharpness.The inserted AMD bilinear filter has not been struggling with this problem but it sure can not go against the flicker. This is only possible due to the higher resolution.

The problem with a bilinear filter is it affords lower quality and flickering issues. Good example here
http://a.dilcdn.com/bl/wp-content/uploads/sites/8/2013/01/downton-bingo.jpg

The 2x2 average is a bilinear filter. The Gaussian is softer but more accurate and the details better preserved, moreover it is more robust to pixel alignment issues thus avoiding flickering. Coping straight from SO
In case it's not immediately clear what I mean, consider the pixel patterns 0,0,2,2,0,0 and 0,0,0,2,2,0. With area-averaging, they'd downscale to 0,2,0 and 0,1,1, respectively - that is, one will be sharp and bright while the other will be blurred and dim. Using a longer filter, both will be blurred, but they'll appear more similar, which presumably matters to human observers.

Which is why a Gaussian filter is preferable. You can adjust the size of the kernel to change the degree of blurring. Ideally afterwards you then need to sharpen.

We can't see the exact effect but we can get a good approximation by downsampling the image in editing software and applying a little sharpening. That will give result very similar to what DSr/VSR does and the images will look similar on everyone's computer regardless of which browser they are using.

Sorry if this has been covered... do we know the exact techniques employed?

Even so it's not very scientific.
