nvidiots were using this as ammunition to go after AMD's unreleased Super Resolution technology as a competitor to DLSS2.0 meanwhile anyone with a functioning brain knew this was a fuck-up and they meant FidelityFX post processing shit. I'd imagine their contacts at AMD weren't too happy about this.
[UPDATE] The official FAQ deleted the answer mentioned in the original story below. As soon we learned this, we contacted 4A Games to get a clarification on the matter. Here's the statement we just received in its entirety:
4A Games has not evaluated the AMD FidelityFX Super Resolution feature for Metro Exodus at this time. In our FAQ, we were referring to the AMD FidelityFX open source image quality toolkit which targets traditional rendering techniques that our new RT only render does not use, and noting that we have our own Temporal Reconstruction tech implemented natively which provides great quality benefits for all hardware, so do not currently plan to utilize any other toolkits.
