i would defintely be in support of using IGT. I just tested Duckstation and its got even much slower loads than epsxe which was already slower than console. I have some runs done here on my youtube channel https://www.youtube.com/channel/UCpGwxony_BjYIB3loN0caJw

(if you want me to just add the runs to the sheet myself just shoot me a message and ill give you my email)

person that posted the sheet deleted unfortunately but here is the new one: https://docs.google.com/spreadsheets/d/1G_ZW6YUKg0DX1Gfs54GXm_2akicjb_3I9JYCV_VhEog/edit?usp=sharing
