@carsono311 well, I was a bit kidding, don't take me wrong 🙂
Regarding question why they didn't implement it, well I cannot tell for certain, but as it is with many games, nVidia is simply anti consumer, even though many people think it is God for all gamers and their problems. They want their products being marketed everywhere so they can sell their crap RTX, which BTW nVidia also took from MS DX12, aka DXR as almost none of people know about... even BF2042 RayTraced occlusion is part of DX12 DXR, but nVidia calls it RTX (to promote even more their graphics card lineup) etc.
Sad thing for gamers, AMD FSR would benefit to all gamers, but as it is now, most people are locked out of the game... even though game has many problems as of now, but this is for another thread.
