Dynamic Super Resolution - SuperSampling ??

[Zelarion]

Is Dynamic Super Resolution (a feature on my gtx 980) the EXACTLY the same as SuperSampling? or is it slight difference...

Also, does DSR do anything besides increase anti-aliasing powers? Like, does it make colors look more rich? or any other thing besides anti-aliasing?

Reason I ask is because the default games anti-aliasing is fine for me in some games I play, but was wondering if it offers and color richness....


Thanks

It's downscaling, where the image is rendered at a higher internal resolution, nothing more. You shouldn't use it past 1440p(2.00x on a 1080p display) on a single GTX 980 with current AAA games.

I have two gtx 980s, does it do anything other than anti-aliasing visually? like... is it supposed to increase color richness?

It's a different way, basically another option to achieve the same quality...

AA (Anti-Aliasing) works by redrawing each of the frames over and over, sharping the edges. You will notice there's already various different types of AA, then they have the amount of passes to do - when you get up to 8x for example, this would redraw each individual frame 8 times, therefore taking a heavy load on the graphics card, making it 8 times the load!

DSR is only available on some Nvidia graphic cards. It sets the game resolution to be higher than what your monitor can handle - which cases the game to draw each individual frame once at a higher quality. Then the graphic card down-samples those frames to the native resolution of what the monitor handles.

In other words: Game runs at 4K UltraHD resolution > Downsampled to 1440p or 1080p (whatever your monitor can handle).

The image edges already look sharper at the higher resolution, so it can calculate them and try keep that quality sharpness when down-sampling it.

Note: It depends strongly on the game and your system how well this will work. Some games mess up, because well 3K or 4K UltraHD isn't really supported that well in the first place and can put a lot more load on the system. If you have any issues, you just have to disable DSR by setting it's in-game resolution to default or under GeForce Experience.

Thank you for all that information, however all i want to know is.... which i keep asking over and over lol, is does this imrpove other things such as surface (not edges) of images, such as color, richness (reds look deeply red, blacks look really black, and so forth), and even texture HD'ness.... or is it just anti-aliasing...

I know what you're going to say, that it increases the resolution and then down-samples that... but my question is... AFTER it gets downsampled back to fit my monitor WHAT EXACTLY is retained (besides the antialiasing).... Is the Textures and color, and quality increased?

How effective it is vs AA depends a lot on the game. You may find that some textures or UI elements may scale better than others depending on the resolution of the original assets. It also takes some fiddling with the smoothness setting - the gaussian filter it applies isn't very good. If you're downsampling you may want to try something like GeDoSaTo if the games support it, you have much better options like Lanczos scaling.

ok I just tested it in gta v... LOOKS ABSOLIUTELY AMAZING at DSR 4k resolution....

at 1080p with max ingame AA = nice but can still see jaggies
at 4k resolution with no ingame AA = literally almost no jaggies

However, my question still remains... Does it improve Textures? Colors? I think I noticed the textures and colors looking better, but I'm bad with remembering how something looked once i change resolutions lolol....

But based on the geforce link you showed above, the image does look more "complete"...

I think i answered my own question... I think DSR simply creates a more "complete" look....

AntiAliasing will be more "complete"
Colors will be more "complete" and thicker..
Textures will be more "complete" and popping, because everything is closer together??

I think i got that right .....

All it does is render the game at a higher resolution and scale it back to whatever your monitor runs at. You can cram more detail into it, but the benefits are limited by your monitor's pixel density. It shouldn't really provide better colors, but an overall cleaner and sharper look, provided the game works well in those high resolutions in the first place.
For example, here's a screenshot of Dark Souls 2 running at 5K through DSR; http://i63.photobucket.com/albums/h152/iHate-You/other/DarkSoulsII_2015_04_23_06_19_46_097.jpg~original
You can see the textures are much more detailed and cleaner, and should look very sharp when scaled back to 1440p, but the HUD elements are so blurry they won't look any better.

On that note, what temp should neither of my GTX 980s during intensive graphical gaming in SLI never go above? because my second gtx 980 while in SLI MODE hit 91c ingame....

what temps during sli is ok? and not ok? thanks

[videogames]

The default temp target should be at about 90C, so over that the GPU will start throttling until it gets to lower temps. It's still safe, but in-game performance may suffer. If you're overclocking it's a good idea to dial back the hotter GPU.
