Yes, I know that Matt, it was just to compare these 2 (and I do know GUI gets upscaled, so that can lower quality). I would assume they're identical but in my case RSR (aside GUI, just the game's image itself) seems to be doing much worse job for some reason. As if only a bit of it worked (just the sharpening pass), not the full thing. However, that can be just me, so I decided to ignore it for the time being. Also, I tried it in FF14 and World of Tanks as well - neither looked good. Possibly something to do with the ultrawide indeed - I know it's supported in theory but maybe something was missed. And of course I can see GUI being much bigger when I change internal resolution, FPS changing too and drivers' GUI showing RSR is working and upscaling - so I know I am applying it properly. Just effect is... meh, in the mentioned 3 games. Still, I can't exclude it's just my own perception and it's working as intended, just from 1080p to 1440p it can't do miracles.
RIS worked fine in previous drivers, but in these ones is just being emo for some reason. Perhaps a bug with UW, I couldn't say. It's not a deal-breaker, but would be nice if it worked as in previous drivers. That said, change log claim that RIS works now also in 3rd party apps (video players etc.) - I assume all I need to do is just turn it on in drivers and the rest happens automagically?
Currently I am at work, so not much time to test further, but later on I can post comparison screenshots if that helps.
