We have introduced a lot of things that seem to be a small version upgrade, but in fact, the function changes are quite large. This time the new driver of the A card came again, although the version number was only upgraded from 22.3 to 22.3.1, but added a fairly important feature - Radeon Super Resolution, referred to as RSR, is another frame rate optimization technology.
Why does the editor say "and"? Many players should remember that the A card has already advertised a lot of FSR (FidelityFX Super Resolution). Now that you have this feature, why do you need to have another RSR? What is the difference between them and what is the actual effect? In fact, when it comes to the difference, it is very obvious in the 22.3.1 driver, that is, the RSR relies on the driver, there is a special switch, and the FSR switch is in the game that supports this function.
From this seemingly inconspicuous difference, we can know the difference between RSR and FSR. RSR theoretically does not require game support, as long as this function is turned on in the driver, and then the game resolution is set to a lower resolution than the actual resolution, the low-resolution image will be automatically raised to a high-resolution output. Compared with the direct display of low-resolution pictures, not only some of the image quality optimization of RSR, but also because it can be displayed point-to-point, there are fewer distortion problems such as jaggedness.
Conversely, games that support FSR use other graphics cards such as N cards and later I cards, but RSR is executed through the driver, which is definitely limited to A cards. As for the effect, RSR is processed at a low resolution, which of course results in higher frame rates. From the overall picture, at least in the center of the field of view and the close-up display, the effect is still good, basically can not see too obvious changes.
In terms of vision and details, the picture loss is certainly still there, and the optimization is also obvious, such as running at 1800P (2880×1800) on a 4K (3840×2560) display, you will find that some corners become more rounded, some materials are more concave and convex, and even some sharpened feelings, but some places that originally have jagged teeth, and the sense of serration is more obvious.
So, how big is the performance improvement? Let's take a look at the actual test of third-party media. The test benches are Ryzen™ 7 5800X, RX 6900 XT graphics. The test includes turning on RSR to simulate high resolution and not turning on RSR, which is actually a case of directly running at low resolution.
Obviously, at the high resolution of the simulation, the frame rate of the game is still basically the same as at low resolution, and the increase is appropriate. Of course, the graphics card and CPU performance used in the test are good, and the performance loss of the optimization process is very small, that is, the gap between 1FPS, and the performance loss of using lower-end models may be larger, but it will certainly not greatly affect the actual effect. If you have a high-end display but the current graphics card has limited capabilities, you may wish to try it first, so that the price of the graphics card will be reduced.
