I tried Optiscaler briefly but decided to use the native implementation of DLSS of the game I was playing. For no particular reason btw, I just didn't notice much difference maybe I didn't apply correct settings. Might give it a try next time I play a game that has it.Try Optiscaler and use XESS with DLSS inputs on AMD 6000 or 7000 series card, then compare it with FSR3.1 implementation in the same game. I have a 6700XT and on Alanwake2 and Cyberpunk, you can clearly see just how much better even XESS looks when compared to FSR3.1/3.0.
FSR4 is way closer to DLSS but the support drop for old generation is sad.
What's worse is that unlike NVIDIA who can use their market domination as a way to push DLSS4 frame gen, AMD doesn't have the same benefit for FSR4's frame gen. FSR4's adoption will 100% be impacted. (I just realised I typed the same thing just worded differently lol)DLSS4 upscaling works on RTX 20 series, not to forget any game with DLSS 3 support can be upgraded to DLSS4 via the Nvidia software (so no need of intervention from game devs).
Sure FSR4 works on FSR3.1 supported games as well but still, there are just a very small % of gamers with GPUs that can use FSR4. This alone is the biggest con of FSR4 & will impact adoption. Anyways, let's see how it goes.
