Wrong! I can see the effect very clear in my shots I have posted.
Open the csgo ones and flick between them, notice how much the aa level increase and how sharp the image becomes.

No I do very clearly get it.

D.P's saying the image displayed in the tabbed window isn't the same as what your GPU displays, as the browser is doing the scaling/downsampling.
Sometimes I feel like I'm walking on egg shells around you. You just explode with rage.

Do you see a difference from the 1080p shot vs 3200x1800 shot?
Yes or no
If my method of displaying the effect is wrong then so is everyone else so far.

How about someone lays out a clear method that we can all stick to instead of all this pedantic bitching?
To re-iterate you can't get what DSR is doing through the normal screenshot functions.
It starts by rendering the game at the specified DSR resolution in exactly the same way as it would for a monitor that was truly capable of the DSR resolution and when you screenshot this is what you get - the unaltered high resolution original with NO DSR processing - the drivers then intercept this before it goes to the monitor and use a filter to resample to native resolution.
(This preserves more detail than the old style averaged interpolation scaling done either on the GPU or monitor as part of the normal pipeline).

I can see the downsampling yes.

So that's a no?
Oh well, I think the pics give a fairly good idea and they all show a clear difference for whatever it's worth.

You will see whatever scaling method either used in the image editing package or the browser for rendering if you take the output from a screenshot with DSR/VSR enabled and resize it which while it gives an approximation of the effect won't be the same unless your using the same filter to resize it and useless for comparing VSR v DSR quality.

So is there a clear way of providing fairly accurate pics?
Resizing via Paint/PS/Gimp is a no go or what? Do we have to then approximate with sharpening? If so, to what degree and how accurate is that in comparison?

Increase sharpening to your personal preference, just like DSR
Resizing in PS/gimp and applying a little sharpening is going to be the easiest way, give more realistic results and everyone will get a consistent image.
Best is to use FRAPS or such like to take an actual in game screenshot when running DSR because that will include whatever post processing and sharpening DSR drivers are applying.
Having the browser do the downsampling is to be avoided because they are notoriously bad at it and everyone will get different results depending on what browser they use.

My personal preference shouldn't have any influence or bearing if we're talking about things being 'accurate'.
I use Afterburner to take screenies and these are all actual in game shots that reflect the level of DSR/VSR. I used MS paint to quickly resize it and saved it in the same format it arrived in.
What should I have done instead?

AFAIK its only possible to do it via hardware capture of the output either with an external capture card (as seen in some youtube videos) or with debug drivers/card.
From a cursory look at them side by side it appears (probably not surprisingly given how AMD has marketed it) that VSR gives slightly superior edge filtering (anti-aliasing) while nVidia preserves intra-texture detail a bit better though its not cut and dried as in some situations AMD is sharper i.e. bright coloured text against a dark blue or black background is readable from slightly further away on AMD than nVidia.
Haven't checked but AFAIK FRAPS will suffer from the same issue - it will hook the frame buffer once the game has done rendering and before the drivers do their intercept for post processing.
You see something but likely very different to what DSR is doing and there is no guarantee what you are seeing is what i am seeing.
To be clear:
*) There are multiple methods of downsizing with different quality and speed tradeoffs. there is n mathematically correct single way of doing it. Web browsers ignore quality and use fast solutions. DSR uses methods that result in higher quality images.
*) When ever you downsample there is a perceived reduction in sharpness so it is paramount that sharpening is applied in post. The amount of sharpening required is at least partially is subjective, which is why it is an configuration option in DSR. There are many different ways to sharpen, again some are faster, some give better results, some emphasize edge sharpness.
So only a true capture form running a game in DSR will give you exactly what is required but the next best approximation is to downsample in PS/gimp and apply some sharpening.
What does AB give you a native screen res screenshot when using DSR or the DSR resolution? If your having to resize it to get native resolution then you aren't getting any of the DSR/VSR processing just the original high resolution rendering untouched by any filtering.
