Pontiac · February 1st, 2007

Hi people,

I have a question, hoping the PSX author himself could answer it:

PSX seems to maintain a constant 60fps rocksolid in ALL PSX games for NTSC, and 50 fps for PAL, with vysnc turned on. This is great and means scrolling is smooth in everything. FRAPS reports the exact same rates as the internal fps reading.

However, EPSXE or ALL other plugin based emus, including project 64 for n64 games, all of them seem unable to display things at full framerate. According to their internal fps counters they are, but my well trained eyes and FRAPS both tell a different story. FRaps generally reports 30 fps for ingame movement sections, and weirdly 60 for still 2D images like menu screens ingame, but as soon as I go out of the menu, 30 fps returns and the scrolling is terrible... I can tell i really am getting half framerate.

People before have told me that some games dont display framerate at full 60 in certain areas etc, but I know this isn't the case as PSX displays full framerate in ALL games.

Can someone tell me why it seems only the plugin emus have these issues, and PSX doesnt, if this the games arent designed for full framerate?
