I don't use it to change settings, more out of curiosity to see what the green machine thinks should be used lol. I use GFE for game recordings and other stuff though hence why I use the app which is quite useful for that. And to be notified the moment a new driver is out.
Yeah GE is fantastic for all of that, prefer look and overall ui of amd drivers but in this department, nvidia are miles ahead imo.
Also with regards to the RT on vs off
Can't see a difference tbh
But yeah aside from puddles/water scenes, RT doesn't add a great deal of difference although some of the lighting parts with GI at the start of the game were very nice. I'm still holding of on playing as thanks to amd, they have decided for me that FSR is what works best for my hardware........
