By the time you actually are able to run games in 4K resolution at constant 60 frames per second, you would need to jump to 8K to get the same effect. Personally I won't be using this method even if it would look better.

I can, and I am right now.

So yeah.


Yay.

It depends which game you have, which GPU you have and how much money you have.
With sub-new or brand new dual GPU solutions, 4k is playable if not optimal for the recent games.
4k is coming and fast, as the GPU's get better: for instance GTX970 starts to have the same amount of juice as Titan, but with less than half the price. Every second year is at least generational leap for every gpu manufactor, as the market war tightens.

I did some screenshots of the old NFS Porsche (2000) in 4K!

Spoiler below!

Supersampling is a brute-force AA method that calculates a pixel's color by forcing the GPU to oversample the frame, or render it at dimensions equal to the resolution times the sampling rate (ex.: native resolution of 1680x1050 * 4 samples = 3360x2100) and obtaining color data from samples around a target pixel before downsampling (reducing) the frame to its original size. After the frame has been reduced a negative level of detail bias is applied to sharpen a sampled object's textures to counteract the blurring that downsampling and pixel merging produces. Supersampling is a type of full-scene anti-aliasing, meaning that every pixel in the frame is sampled and corrected rather than just those lying on the object's outer boundary, lending it to offer exceptional image quality but at an enormous cost to performance due to the GPU being required to compute so much additional information.

Supersampling produces the best AA results, at the highest performance cost. https://www.youtube.com/watch?v=8fYuKusjtY8#t=68

Amnesia has no AA, which may be the case with some titles. This method might be preferrable in those cases, in order to achieve AA (as long as your computer can run it). If the game has AA you're more often better off using the game's native alternative as that will be better for performance.. Unless that alternative is FXAA, in which case one may want to use SSAA instead.. Smile Just personal preference as FXAA can blur textures (blur all the things!):

As you can see, FXAA 'loses' all of the specular highlights when it's shown in the gif. You can also see the right shoulderpad becoming blurry (as well as some textures on the back becoming blurry).

And then there's this new antialiasing called "TXAA", which is used by Nvidia in some games.
Maybe the best aliasing effective wise, although the most performance heavy.
Not to mention Ubersampling of Witcher 2, which is another story.
However, I rarely use antialiasing methods anyway; it's hard to reach 60 with newer games when enabled. I've got used to even larger amount of jaggies, maybe that adds also why.

No, that would be SSAA, which is discussed in this thread Smile TXAA does seem to be 'a step above' MSAA/CSAA: http://www.geforce.com/hardware/technology/txaa/technology

RE: 4K gaming - Red - 11-01-2014

Okoi, never looked any deeper on the subject, but TXAA is something Nvidia has hyped recently. Thus I deduced it is the best, and was wrong. Thank you, you saved my life.

RE: 4K gaming - Acies - 11-01-2014

Decided to make an example of my mod Spacies:

Due to image compression it might be hard to see actual difference (uploading to sites compresses images and all that) so I've also made a gif to clarify.

Oh, so I was right when I felt that Call of Duty: Ghosts felt blurred when I tried FXAA.
