I ended up using ePSXe vs Retro Arch as I went through the forums, but I am noticing some faster games (Like DDR, Bust A Groove for instance) I get some severe lag in these games. Even Lunar has a small bit of noticable lag during big combat, and I'm wondering if this is common or if there is a setting I should look into? I followed a lot of the 'best settings' like 1x overclocking etc, but I still notice these smaller issues.
I do play with a wireless controller so I am expecting that lag, but it's gameplay lag I am struggling with. I play on my gaming PC (Way over-kill for emulation) on my 4K TV at that res.
