Downsampling vs actual monitor resolution ?

i run a 720p monitor at 1080p , noticable difference in image quality things appear smoother and less jagged, waiting on a decent monitor upgrade so does the job for now

LCD do not do well at non native RES.

Downsampling is not the same as you forcing a higher RES on your monitor.
 
Downsampling, as the op refers to and other people have mentioned, is using a tool such as CRU that allows you to run your monitor at a higher res, such as running a 1080p monitor at 1440 or even 2160

When running games this has the advantage of a very high quality - but obviously very resource intensive - antialiasing

The way that CRU works is that it exactly is forcing a higher resolution than the monitors native resolution
 
That is not actually downsampling or SSAA then and again LCD are poor at non native RES.

I can use a higher than official RES also but is not downsampling and eventually I will get an "out of range error"

I can however set a higher RES then scale it back down.

Nvidia does not need any 3rd party Apps to do so, the scaling is in the NVCP.


QUOTE:

"You should then have a custom resolution list that has your new resolution as shown below. Make sure you leave your desktop resolution as your native. If all went well, from now on when you load up games you should have the new resolution available. When you select it, it will downscaled to fix your screen. Great for games that don't support AA, or for people using video cards vastly more powerful than the monitor native resolution they are using can take advantage of."

Your setting up a custom resolution, tricking the game in to thinking you have a higher res monitor than you do, that you are leaving the desktop on native and only using the custom resolution within the game is irrelevant, what you are saying is "bad" is exactly what you are doing
 
You really do not seem to have grasped the fact the monitor is still outputting at the same native RES if you do downsampling as the link in Guru3D states which is same as SSAA does.

The monitor is not doing 2560x1440p when it can only do 1920x1080p (pure example).

Has nothing to do with what I say is bad, its well known LCD are only at their best at native RES.

Gregg understands it in post #11.

I have no clue now by this confusing since your input if the OP is really talking about Downsampling like in the Guru3D link or Upscalling in some sense as you are talking about.

You have two 670s for 720p?

For now, about to buy a much more suited monitor, so running games at 1080p downscaled has been very beneficial there is a difference in image quality vs 720p and has given me a great estimation of what FPS im likely to get
 
Is this thread some sort of joke? you cant run 2560x1440 or a 1920x1080 monitor. If you scale down a higher res you're just getting a 1920x1080 scaled image.
 
TBH I am now not sure what the OP means after all the confusion but if he really means Downsampling (aka homebrew SSAA) then read the Guru3D link I added before.

The game will internally be running the higher RES and giving you lower FPS but yes you are correct the monitor will be displaying at 1920x1080 but the game should look less jaggy like really good AA.

On topic of running a higher RES than native I used to be able to force 1920x1200 on a 22" Sammy 1680x1050 LCD and it was displaying at that but its blurry for text as non native and once proper driver was installed it would not let me do so.

Using either nvidia control panel, or a tool called CRU, you can and it basically means you get a very intensive but very good quality anti aliasing

No the monitor is not magically displaying more physical pixels, but there is still a benefit from doing so

This is now the default behaviour if/when you force a higher than native resolution, not sure why jh keeps banging on about a weird error he managed some years ago, when everyone else in this thread is clearly talking about using downsampling AA

And to answer the OP's question, I believe that if you are running at 1080p and chose 2x supersampling (on AMD, anyway) then the GPU is rendering internally at 2560 x 1440 then the game is running exactly how it would be if you had a true 2560 x 1440 monitor.

4x Supersampling is the equivalent to how the game would run on a 4k monitor

etc etc.
 
@ andybird123 , no you are the one that got the thread confused.com.

The thread was about Downsampling before you joined it (I added to it in post#10).

What you said and what you claim you said are 2 different things.

I just explained both to him and what error?

The Op was talking about downsampling, other people were talking about downsampling, murah said he was doing downsampling and you told him he wasnt, he has since clarified and again said that he is doing down sampling

You seem to think that the one of many methods youve found is the ONLY way to do downsampling, but it isnt
 
I found nothing, you were saying the monitor was displaying the higher RES initially, at least 2 others inc myself said it was not.

Me making my old monitor run a higher non native RES is not downsampling the higher REs was displayed though not as sharp.

Go round and round all you like its kind of boring TBH.
 
I never said that a lower res monitor can actually display a full higher res, please quote where i said that

The default behaviour in both AMD and nvidia drivers is for the GPU to re-scale a higher res image to the monitors native res, you can set the monitor to be the scaler (as you are saying then looks not good) but it isnt the default behaviour

You quoted someone who has 670's, so unless he went out of his way to screw things up, yes he is doing downsampling

The situation you seem to be talking about with your old samsung would be the result of a driver error, which you yourself say was then fixed in a later driver, here in the now, if you use nvcp or CRU to force a higher resolution, the default behaviour is that the GPU does the scaling, so the guy you quoted and told him he was not downsampling, actually is
