A good chunk of PS5 games use it like Ratchet and Clank Rift apart, Spider Man 2, Black myth wukong etc. it’s usually used in the performance/rt modes or performance modes. I mean if the game runs smoother what’s the big deal using the technology. I would rather have so called fake frames then it running trash.
I've had a RTX4090 since launch and have used frame generation on numerous games for nearly 2 and a half years... and for the most part its fantastic!
The picture quality is generally great, and the massively boosted frame rate feels like magic! In real use I don't even find the added latency that bad - the only not great experience I had was with Silent Hill 2 Remake where the FG artifacts were quite noticable.
But I've kind of realised that the majority of people who hate frame generation havent even used it - and hold onto latency as the biggest problem...
The real biggest issue I think, that most people are overlooking, expecially with the RTX50 series launch - is that hardly any games support frame generation!
The vast majority of DLSS enabled games dont have frame generation - I think in all this time I've only played about 30 games that natively supported FG - out of the ~300 games that support DLSS (upscaling).
With the RTX50 series cards Nvidia confirmed that only 75 games at launch will have DLSS4 multi-frame gen support - that almost a non existant fraction comparted to all the avaliable games out there!
So you could have a fancy new expensive RTX5090 - but for the vast vast majority of games you could play, hardly any will have frame gen support, let alone multi frame gen...
It kind of feels like a lot of people are deluded into thinking frame generation will work on "every" game automatically...
