If you were not around, you wouldnt remember, but this is not new from AMD.
Evergreen support was atrociously bad. Games broken, crossfire broken, ece. Then GCN came out. 3 years after GCN released, Evergreen was dropped. Not just optimization, but EVERYTHING was dropped. The drivers were left broken, and they still are broken. The Fermi cards, OTOH, received driver updates for 2 years after evergreen was abandoned, and even back in 2016, Evergreen was unusable in games like Fortnite and had substantial issues in games like GTA V, whereas the fermi worked across the board.
They also have a long history of ignoring problems and the community. Frame pacing was a chronic issue on AMD, with people complaining in forums about "smoothness". AMD insisted it was user error. Then nVidia released the FCAT tool for tracking frame time pacing, and it showed that AMD single cards had worse frame time pacing then nvidia SLI setups, let alone single nvidia cards. Within 12 hours AMD released social media posts acknowledging there were "long standing issues" with the drivers. Womp womp.
They broke 16 bit OpenGL in catalyst 13.7, meaning that retro gaming became an impossibility. They fixed it by accident in 16.4. Which didnt release for Evergreen, so if you had old cards, get bent. Never acknowledged that they broke it either. This was when I abandoned AMD laptops, after my Asus K53TA-BBR6 was left unable to play games like Dark Forces, or Doom.
Just...the entire history of the Radeon VII card.
The fury X, the "overclockers dream" was discontinued after only 6 years.
rDNA1 was abandoned after 7 years, shifted to "maintenance mode" for only critical bug fixes and security updates. rDNA2 was moved as well, despite being only 5 year sold at the time and being sold up to 3 years ago.
AMD has had to fight hard to overcome that incredible negative reputation, only to torpedo it int he last few months.
DLSS4 has been implemented in over 100 new titles. It has also been backported to the RTX 4000, 3000, and 2000 series. They average 10 years of support. The nVidia app allows you to inject DLSS4 into older games and use older DLSS in newer games when needed.
FSR4: 10. 10 games. Not backported to anything. AMD seems to think 4 years of driver updates is sufficient now. Reliant on third party open source tools for FSR injection.
That is why people sped hundreds more on the nvidia experience.
