I remember for about 25 years ago, I bought one of the first 3dfx card in the country. Later on I was playing the game EF (eurofighter) 2000. The first version was a DOS game with ofcause a corned graphic. But then someone made a big patch on about 9mb (took all the day to download that time) for to support the 3dfx. That game become a miracle.
But when I talked about 3dfx to friends and even in most data stores, they did not know what I was talking about, because the card was a test ware that a local store had.
But after a half year everybody shold have one.
In the beginning it was only one official game that was supporting it. Microsoft Monster Trucks.
DLSS 2.0 will be the furture for a long time. Just wait and see.
