AMD FSR has the potential to breathe new life into getting older graphics playing cards, and make the steadiness between recreation efficiency and visible high quality simpler to realize. However what precisely is FSR, and the way does it work?
What Is FSR?
FSR, which stands for FidelityFX Tremendous Decision, is likely one of the newest additions to AMD’s FidelityFX picture toolkit. It’s an upscaling expertise, designed to enhance the efficiency of video games with out lack of picture high quality and graphical element.
Enjoying a recreation in excessive decision corresponding to 4K will typically end in a noticeable body fee drop, even when utilizing an honest graphics card. That is very true if the sport makes use of demanding results like Ray Tracing. FSR can cut back the enter decision to as little as 1080p after which upscale the output to look near 4K. You get the efficiency of the decrease decision however with the visible element of a a lot greater decision.
It really works by decreasing the render high quality of a recreation after which analyzing the picture, detecting edges, and reconstructing them on the greater goal decision utilizing a spatial upscaling algorithm. A sharpening course of can be carried out to easy out particulars additional. All of that is carried out in a single go in the course of the rendering course of, with GUI components and textual content added to the body afterward.
FSR is just like NVIDIA’s DLSS or Deep Studying Tremendous-Sampling. Though they aren’t strictly comparable, the identical finish result’s achieved: the next decision picture for a decrease efficiency price. One essential distinction is that FSR is open supply, and probably out there on any graphics card. Whereas DLSS relies on utilizing an NVIDIA GPU.
Which FSR Scaling Mode Ought to I Use?
FSR has 4 totally different high quality modes to select from. Efficiency mode applies essentially the most scaling at 2x the enter decision, and Extremely High quality mode the least at 1.3x the enter. The 4 modes and their scaling ranges are:
- Efficiency Mode = 2x scaling
- Balanced Mode = 1.7x scaling
- High quality Mode = 1.5x scaling
- Extremely High quality Mode = 1.3x scaling
So for instance, to realize near 4K utilizing High quality mode, the graphics card solely must render 2650×1440 pixels quite than 3840×2160. FSR then scales up the picture by 1.5x.
Upscaling, even the clever spatial upscaling that FSR makes use of, isn’t an ideal course of. The extra scaling utilized to a body, the extra probably graphical errors will happen on display screen. AMD itself states that “Efficiency mode visibly impacts picture high quality and will solely be chosen in conditions the place the necessity for the final word in efficiency is vital.”
This is a matter that AMD has no less than partially addressed with the discharge of FSR 2.0.
What Is FSR 2.0 and How Is It Totally different?
The primary model of FidelityFX Tremendous Decision was launched in mid-2021, supported by a number of high-profile video games, together with Cyberpunk 2077 and Godfall. FSR 2.0 was launched in Could 2022, not as a substitute for 1.0, however along with it. Which means recreation builders can supply customers a alternative between the 2, probably making FSR out there for a wider vary of {hardware}.
The primary distinction between model 1.0 and a pair of.0 is the swap from spatial upscaling to temporal upscaling. Spatial upscaling makes use of knowledge from the present body to upscale the body itself. Temporal upscaling can use knowledge from each the present body and former frames, leading to improved picture high quality and fewer surprising visible artifacts.
FSR 2.0 additionally permits recreation builders to tweak the totally different scaling modes. Because of this video games that use 2.0 may need solely three modes out there, or embody Extremely Efficiency mode quite than Extremely High quality mode.
One of many downsides to this improved upscaling high quality is that FSR 2.0 is extra demanding on the graphics card. Due to this, the variety of graphics playing cards AMD recommends utilizing to realize some resolutions, significantly 4K, has shrunk.
How Do I Use FSR?
If the sport and your graphics card assist FSR, there may be often little you must do past selecting between the 4 FSR modes. In case your card and the sport helps a number of scaling applied sciences, you will have to pick out FSR earlier than setting the mode.
The FSR modes could be discovered within the graphics settings for every recreation that helps it, often within the decision part however typically in a separate upscaling part. Precisely how effectively the totally different modes work will depend upon a number of components, together with the graphics card you’re utilizing and the sport being performed.
It’s possible you’ll have to replace your graphics drivers to the newest model earlier than you may apply FSR to your recreation. If the setting remains to be unavailable after updating, it signifies that your card isn’t able to utilizing it.

Video games That Help AMD FSR
There are over 110 video games that assist FSR on the time of writing, with extra being added on a regular basis. Help for FSR 2.0 remains to be pretty restricted, however the record is certain to broaden shortly, both by means of patches for present video games or as new video games are launched.
FidelityFX Tremendous Decision was made out there to builders of PlayStation 5 and Xbox Collection X/S video games in mid-2021. Few video games presently assist it, Arcademageddon being one, however you may anticipate extra to come back.
Listed here are simply among the video games that assist a number of of the FSR variations:
- Anno 1800
- Arcademageddon
- Murderer’s Creed Valhalla
- Black Desert
