When you have more time to talk about games, than actually play them.
Nvidia is the reigning champ of the gaming graphics card industry. AMD has made great progress, but the advances by team green are hard to surpass. The GPU processing power of their cards keep improving at a rate that keeps them ahead of all competition.
The most recent Nvidia innovation includes ray tracing (RTX) and deep learning anti-aliasing (DLSS). This combination of technologies will keep the Geforce cards ahead of the curve by months, if not years.
The Nvidia RTX tech simulates the actual path that light takes from various sources to produce a more accurate image. It looks great, but takes a lot of processing power. DLSS renders the scene at a much lower resolution, reducing processing power needs, then uses AI to upscale to the preferred resolution. The combination of the two technologies allow for more accurate graphics without the huge performance hit.
This advancement started with the Nvidia Geforce 2000 series, but at a steep price for a decent increase in performance. The secret was in the great advancement in RTX performance that normal GPUs could not handle. There were not enough games that took advantage of the tech to make it truly worth the price, but the game, Control, was a great show piece.
Nvidia really perfected the RTX/DLSS tech in there 3000 series. It also had the added bonus of huge performance boost in non-ray traced gaming over the previous generation. This led to the cards constantly selling out as everyone rushed to get one for the most hyped game of all time: Cyberpunk 2077.
