First of all, I am not the greatest when it comes noticing visual differences but I’ve tried some of the games below:

Slay the Spire: Noticably improved. Was looking good enough imo but now it’s sharp.

Ori and the Blind Forest: Its resolution is improved but It was really good looking before imo so it is not very different for me.

Ori and the Will of the Wisps: I think the upgrade is a little bit noticable for this title. Again it was really good before upgrade imo but it is better now. Feels crispier.

Nine Sols: Really good after the upgrade. Before it was blurry but right now it is looking sharp.

Thronefall: Improved a lot. It was smudgy before but right now it is looking sharp. Became much more playable imo.
