I'm running a RTX 2080 Super / AMD Ryzen 9 3900X / 38 GB ram I know its pretty old, but I don't believe I should have an issue running this game at 60 FPS. For example when using the 60 FPS mod. When I'm in Rougeport it drops to 40-50 FPS and the game play is in slow motion from time to time. Also thank you for responding to my questions! Really appreciate it.Idk about your first question. I use it in ryujinx just fine as is. As for the second question, it probably depends on your computer. I never see it drop below 60, but have problems with some of the in game timings.
