I have been diving into settings all week, reinstalling RetroArch, updating cores, updating drivers, etc etc. All in an effort to get PSX games to run fullspeed. I have an i5-14600k and an AMD RX-7800XT, so I think it should be up to the task. I was going mad trying to figure out what I was doing wrong.
I finally found it though. There is a noticable 5fps drop in any PSX game when I change from PlayStation Controller to DualShock. I tried searching, but I haven’t seen this documented anywhere. I only saw one user asking about it, but no one had responded.
I am using Beetle_PSX_HW, but I am seeing the same behavior on SwanStation as well. This occurs regardless of any other core options that I can think to try, and any renderer (though I typically use Vulkan).
Has anyone run into this issue? has anyone been able to solve it? I have to choose between Analog control or fullspeed currently, and it’s a total bummer. I appreciate any insight anyone could provide.
