How does Nvidia's DSR multiplier work?

[Chintan Dave]

In Nvidia control panel there is DSR settings with multipliers like 1.2x, 1.5x, 3x, 4x, etc. So how do I exactly multiply these figures to my resolution? My native Resoltuion is 1600x900. So how do I multiply?

You don't need to? It will take that number, render internally to 1600x900 * that number and then downsample it back to your res. The bigger the number, the harder it has to work but theoretically the better the image.

But how would I know that the resolution in the game settings is "THE DSR Resolution?" I mean, there are lot of higher resolutions other than my native res in game settings, which are useless to me as the display goes out of range in those higher resolutions. So how do I know that "that" resolution is DSR one? That's the reason I asked the question. 😀 . Because then I will just multiply it myself and then I can know that "that" resolution in the game settings is DSR one. lol

The resolution in game is the displayed resolution.

What happens in the background that you can't see is affected by the multiplier. You cannot see this res image and neither can the game, but the multiplier works with the asked for resolution * the multiplier within the driver. So in the driver, set the multiplier as high as you can while maintaining a good fps, in the game stick to the normal display res - everything else happens behind the scenes.
