What do you mean exactly with 'downsampling' ?Ls777 wrote:If you have a really powerful graphics card, you can get better AA on the highest graphical settings by downsampling
downsampling is the opposite, it means using a resolution higher than the native resolution of your displayTMarc wrote:use lower display resultion? the game would be a bit faster
Interesting, but isn't that risky to do so ?!? I have a GTX 660 ,Is this card able to "downsample" ?TheBigG. wrote: downsampling is the opposite, it means using a resolution higher than the native resolution of your display
I think it makes absolutely no sense to take a higher resolution as you suggested, because this adds even more load to the system.TheBigG. wrote:downsampling is the opposite, it means using a resolution higher than the native resolution of your displayTMarc wrote:use lower display resultion? the game would be a bit faster
yes. goal is to get a better quality, not more frames hopefully it is now clear for you?TMarc wrote:I think it makes absolutely no sense to take a higher resolution as you suggested, because this adds even more load to the system.TheBigG. wrote:downsampling is the opposite, it means using a resolution higher than the native resolution of your displayTMarc wrote:use lower display resultion? the game would be a bit faster
.It’s particularly useful when the game engine doesn’t support anti-aliasing; you can emulate AA simply by rendering the scene in a bigger resolution, then downsample it to the target resolution using an appropriate filter. So let’s say you are able to render games in 2160p resolution on 1080p monitor, that’s like a 4x Full Scene AA for you right there. Also it’s usually better than forcing or injecting AA, since such options can cause glitches, or are just non-existent for your game.

What kind of performance to expect? Roughly speaking your performance will be 1/N, where N is supersample value or "how many times more pixels you're rendering".
Example : When downsampling from 3840x2160 to 1920x1080, which is technically 4XSSAA, you're rendering 4 times as many pixels at 3840x2160 as you are at 1920x1080, so you'll be getting 1/4th performace. E.g, if you have 120 fps at 1920x1080 you'll get 30 fps at 3840x2160 in game X ( barring vram limitations, other bottle necks and everything in between ).
