What do you guys think of downsampling?

[Chivpcgamer]

Heres an article I read:

 

http://www.neogaf.com/forum/showthread.php?t=509076

 

The reason im interested is that I think the 200% supersample or whatever it is on bf4 is fantastic on my 1920x1200 monitor

 

Im not sure that downsampling is the same is this supersampling but it must be similar

 

So is this a good idea? does it work?

 

If not is there any better way of applying a bf4 similar sharp sampling onto my games?

Sounds like a load of crap just like all "pro" youtubers downsample to 720p

Down sampling is just another way to say super sampling. They are the same thing basically.

Well isn't downsampling what Linus does when he does a video?

He shoots it in about 2k or so but when they edit and render it out, it's at 1080p.

 

And because of this, a native 1080p camera won't look as good as a higher res camera that has been re-sized down to 1080p.

Yes, it is the same thing.

 

You can try forcing SSAA on some games in the drivers (Super Sampling Anti Aliasing), but it will stress your GPU lots.

Its confusing because this guy is basically saying you can run 2560x1440 on a 1080p monitor, which would surely be up-sampling..

Ive used SSAA in Nvidia 3d setting a lot and it doesn't seem to really do anything, unless im doing something wrong..

Most films are downsampled aren't they? Shot in 2K/4K then rendered in 1080p

oh true... i get confused which ones which lol.

Hmm?

 

Downsampling = Scaling a high res image down to a lower res display

Supersampling = Rendering a higher resolution image than necessary in order to then downsample it.

 

So they're technically not the same thing, but supersampling involves downsampling, if that makes sense.

They are the same thing with two different names. 

I don't see any difference at all. You just said the same thing in two different ways.

its pretty great, shame it doesn't work on AMD drivers anymore

Well there is a difference, but you can use them interchangeably for the most part.

 

Downsampling = can be used to describe any image that has its resolution scaled down. For example if I take a 1920x1080 image and then scale it down to 1280x720, I have downsampled it.

 

Supersampling = creating a bigger image than you want, and then downsampling it before displaying it. For example if I want a 1280x720 image and I got a vector file. If I first render the image at 1920x1080, just to then downsample it to 1280x720 then I have used supersampling.

 

 

Downsampling is more generic while supersampling is used specifically when you create the file from scratch, and downsample it right after. At least as far as I know.

I think the difference is in the purpose of why you did it.

Downsampling is simply because you have to. Such as if you have a 720p TV but a 1080p video. You have to down sample it to actually view it.

Super sampling is for the purpose of better clarity (such as the properties the image attains that is very similar to AA). 

But effectively, they are the exact same thing. You just use a different word depending on why you do it.

The difference is downsampling you already have the high res content (can be movies, photos, graphics), so you have to downsample, while supersampling is rendering at a higher than needed resolution on purpose, for the purpose of downsampling to increase quality.

 

You can't supersample a photograph, because you already took it at a specificed resolution, while you can supersample a game because you can choose to render it at a higher res on purpose.

I can imagine it would stress your gpu hardcore and if you are running eyefinity in any way (multiple monitors maybe not in a group),

that it would probably cause a good deal of chaos.

 

Now that being said the techie in me wants to try this really bad, but with 13.11 drivers it won't work. I will try it in the future.
