DLSS VS FSR In Call of Duty Vanguard and why both are necessary
DLSS VS 4K Native – Does DLSS Look Good?
After playing Call of Duty: Vanguard with and without DLSS enabled, I can confirm that DLSS’s highest quality modes are practically indistinguishable for native resolution rendering. In this case, Nvidia’s AI upsampling technology has once again delivered results that are almost indistinguishable from native 4K.
That said, at lower settings, aliasing becomes a lot more visible in motion. This is especially evident at 4K with some straight edges. Even so, in Quality and Balanced modes, DLSS delivers impressive Faux-K results and does so at much higher framerates than native 4K rendering.

FSR VS 4K Native – Is it as good as DLSS?
Call of Duty Vanguard has a strong implementation of AMD’s FidelityFX Super Resolution technology, delivering results that are hard to distinguish from native 4K when Ultra Quality mode is used. Thanks to AMD’s sharpening technology, FSR’s highest quality mode is actually sharper than a native 4K presentation in many areas.
In lower-quality modes, FSR continues to deliver impressive results, but with each quality drop, aliasing becomes more visible. This is especially true for Balanced mode and lower settings. Even so, FSR is a useful way for PC gamers to enhance Call of Duty Vanguard’s performance without major visual compromises.

FSR VS DLSS – A Clear Winner?
Which technology offers the best visuals? FSR or DLSS, who wins? In my view, both technologies are a win in Call of Duty Vanguard, with the highest settings for each offering nigh-indistinguishable visuals for native resolution rendering at 4K. In this regard, FSR wins due to its broader hardware support, but at lower quality settings DLSS has its advantages.
DLSS does a better job at handling aliasing than FSR, with lower quality DLSS modes showcasing similar levels of detail to FSR while offering users sharper edges. This is visible in several areas of the images below.

FSR VS DLSS with lower baseline resolutions
As we use lower baseline resolutions with DLSS and FSR, it becomes clearer that DLSS is better at handling aliasing than FSR, with differences between both technologies becoming clearer in the images below.
With both technologies, we can see that neither tool can properly display the barbed wire in the image below, highlighting how both technologies can fail when using baseline screen resolutions that are too low.
