This looks really good! tried to play it through the HPS1 2022 demo disk and unfortunately the game ran at like 15 fps... i have a mid/high tier pc so that's a bit odd.
Tried playing through the patched version downloaded right here and it's the same, everything including the menus seems to be locked at 15 fps which made me dizzy (except the intro scene which played normally).
I have a 74hz monitor so i don't know if that could be the issue...
