RTX players should all know what makes DLSS powerful, simply by using temporal feedback and deep learning to render gameplay at low resolution, and then algorithmically elevating the resolution to a level comparable to native or even higher.
This results in an increase in the game's frame rate with virtually no loss of image quality.
DLSS operating model
AmD here to launch FSR technology, the principle is sharpening algorithm processing, the same can achieve the effect of increasing the frame rate, but the relative picture quality will be slightly sacrificed.
However, FSR wins without restricting the graphics card model, not only can its own A card be used, but even the castaways of the N card next door have the opportunity to drink a sip of milk.
Since AMD announced the FSR, NVIDIA has emphasized several times that its own DLSS and AMD FSR are not a dimensional technology, which is unique and much more advanced. While players are also well aware that DLSS finches eat cowhide, what's the use?
At best, it is a little incense added to the air, and it cannot be touched.
NVIDIA may also be aware of the rapid decline in word of mouth in the past year, so it sacrificed a big killer.
NVIDIA Image Scaling (NIS) technology was upgraded in the NVIDIA 496.70 driver a few days ago.
In simple terms, NIS is similar to AMD FSR, which belongs to the image scaling algorithm and has a good frame rate improvement for both 1440p and 2160p resolutions.
At the same time, because the principle is simple and rude, the adaptability is better than DLSS, and the game does not need to be compatible with this function, and the frame rate of any game is supported from the driver level.
Although the effect is certainly not as good as DLSS, after all, it is the function of the old graphics card that can also be white, and it cannot be required too much.
Want to turn on this function, the graphics card needs at least 9 and above, desktop notebooks can be, but the notebook monitor must be a single display direct connection, the notebook comes with a display is not, it is recommended to use an external display test. Then you need to update the N card driver to 496.70 and above.
After the upgrade, the NIS function can be enabled on the settings page of NVIDIA GeForce Experience.
Compared with the table provided above, choose the most appropriate zoom factor, the larger the percentage, the better the quality, but the less the increase in frame count.
After the setup is complete, enter any game, and the virtual resolution selected in NIS will appear in the game's quality settings interface.
Be sure to choose a virtual resolution, don't worry about the picture is too blurry, because the graphics card will sharpen the picture through the algorithm to enlarge the picture to the native resolution of your monitor, and the loss of image quality will not be very large.
In Call of Duty: Vanguard, the logs on the wooden house look sharper under DLSS, and the green crate next to the wall also shows some jaggedness around the edges of FSR and NIS, which is a paid feature after all, and there is nothing wrong with it.
FSR and NIS are essentially the same principle, so the results are very close. DLSS looks much lower, but graphics cards that support DLSS should pay more attention to image quality. It is important to note that because our graphics cards vary in performance. Therefore, the percentage increase in frame rate in the table is more valuable.
Dead Loop Graphics DLSS Needless to say, the Expand Your logo in the background in NIS mode loses texture and the horizontal bars on the roof appear heavily jagged.
Even so, NIS is much better than FSR. The Expand Your logo under FSR is basically unrecognizable, and the cable connecting the flag at the top of the scene disappears.
Curiously, in terms of frame rate, FSR continues to pull crotch, even worse than DLSS, and it seems that the compatibility of the death loop with AMD is really not good.
In Marvel's Avengers, the gap between the three modes is very small, and DLSS still shows the best picture quality, but if you don't look at the details, the gap is not obvious.
To summarize, of the three techniques for increasing frame rates, DLSS is unique in that it can increase frame rates with little to no loss of image quality. But if your CPU doesn't support DLSS, then AMD FSR and NVIDIA NIS are decisive. Both can greatly increase the frame rate, although there is a certain loss of image quality, but the sacrifice is still within the acceptable range. NiS and FSR use basically similar technical principles, unfortunately FSR requires games to be adapted specifically to use, which also leads to the performance of games that are not adapted in the test of dead loops. It can only be expected that AMD will integrate FSR into the driver level in the future.
