What is FidelityFX CAS in Modern Warfare 2? How it works
ActivisionWhat is FidelityFX CAS? In Modern Warfare 2, you might see this option appear if you’re a keen-eyed PC player. The function allows you to sharpen the image, making finer details look much more pronounced.
Modern Warfare 2 is finally here, and while the console version of the game might have a couple of options to play around with, PC players have much more flexibility. The game supports Nvidia Reflex, which helps you cut down on system latency, but there’s more. Some users are wondering what one of its options, FidelityFX CAS actually does.
What does FidelityFX CAS do in MW2?
FidelityFX is a package created by AMD that enhances the image quality of your video game. CAS is shorthand for Constrast Adaptive Sharpening. It essentially takes the image and can increase the sharpness of pixels. Areas will less detail will become sharper. This is intended to bolster TAA (Temporal Anti-Aliasing), without any of the blur. CAS can also support upsampling and downsampling of the rendered image.
In Modern Warfare 2, enabling FidelityFX CAS could enable you to see enemies with slightly more contrast, versus having the function turned off. This could potentially help you spot enemies from further away. Though, some might not be a fan of the oversharpened look. It helps being out subtle details in-game, and could potentially prove to be a competitive advantage in this relatively safe entry into the franchise.
MW2 FidelityFX CAS: How to enable it
Dexerto To use FidelityFX CAS, all you need to do is follow these simple steps:
- Open your graphics options in Modern Warfare 2
- Navigate to the ‘Quality’ tab
- Under ‘Upscaling/Sharpening’, select ‘FidelityFX CAS’
