With the SI Optix Curved LED Gaming Monitor, I would fire up Control, Metro Exodus, and Red Dead Redemption. A great monitor like this deserves the finest looking games running on it.
I would be playing Escape from Tarkov and some Red Dead Redemption 2 Online, with maybe a hint of Hunt: Showdown in there. Would look amazing on that nice big Monitor!
I will start testing with old, good Crysis. Then I will move to Witcher 3 and finish it fourth time and lastly I will play Red Dead Redemption 2. I am planning to play dead to outside world until these games are finished.
