I've spent a considerable amount of time testing this over the last couple of weeks and overall, I'm impressed. It hasn't reinvented the wheel or anything but is mostly easy to use. Once installed it might not be able to optimize the games it has profiles for right away but can usually do so after a day or so. I've got ~25 titles it has profiles for and it has managed to optimize most of them.
The things I like are for the games that support it, the ability to override DLSS with DLAA. This includes games that don't inherently provide that option. I also like that it will by default turn off post processing stuff. You can also configure defaults that will override NVCP settings, either per game or global. Also like that I can grab drivers from here and install as needed.
Cons. It's mixed blessing that it seems to look at your display to configure the best settings for its native resolution. While this can be nice if you plan to do that it doesn't take into consideration that you might perhaps use 1440p instead of 4K for better performance. I also noticed something very weird in that it always defaulted to using the DX11 version of TW3. I sort of get it since you basically have to have an RTX 4090 or similar to play the newer RT version at 4K but I was never able to get it use the DX12 and ironically it would enable the DLAA override for the DX11 version. Not 100% sold on the menu/GUI but it could be worse.
Overall, pretty happy with it and it's definitely better than my previous experiences with GeForce Experience. I plan to somewhat keep using it and I'm honestly surprised at how great it has CP2077 and Indiana Jones running on both rigs but I did manually change the resolution to 1440p for the 4080 SUPER so that I could re-enable all RT settings. Otherwise it really made CP2077 at 4K run great on both cards. I haven't tried it with my laptop yet but perhaps will come next weekend.
