hello all. I just ran my first psx game and I have to say OMG i am so rejoiced !!
THANK YOU SO MUCH TO PSX AUTHOR!!!
I can't wait to dig in and replay all the classics. I loaded FF9 and it plays very very nice. But it only plays smooth (and even lags a bit) if I play it in a small window. if I maximize the window (that's how you enable full screen right?) then it lags a lot and the sound too
so I was wondering if having a much better video card would make it run much faster? Right now I have a 6600gt but I'm thinking of getting a x1900xt very soon.. will that boost perforfance (both sound and graphic) by a lot ?
and also.. i was wondering if there was any advantage to using another bios then the 1001 bios ?

1001 is the only biios you can use to play ntsc titles here in the us.
obviously haveing a bettet computer systems makes all the differnece. you might have a bottleneck like limited ram or harddrive space, slow processor or 100 million processes running in the background.

Video card unfortunately makes little difference because it is running in a software mode.
I get similar problems if I try and up the frame rate for too long (using backspace). It has a very negative effect over time (maybe an hour and a half and I have to restart) but as long as I just play the games as they were meant to be I can get a solid smooth frame rate for at least 4 or so hours before it sucks my memory down and gets a bit choppy. Some games I've noticed, though, are exceptions (Granstream Saga for example) and when the models zoom in, despite not being very graphic intense (ugly, ugly game) the skipscore goes crazy and raises by the thousands.
I admit it would be nice if there were at least an option to use video memory... since I have a 256mb card.

i think it would be very possible to render the scene at a low resolution, and then maybe add interpolation to make it look like it does now... right?
especially with dx9 vid cards...
obviously not all vid cards are dx9 BUT i think it'd be nice if we could get a slight boost from our gpu instead of using the cpu entirely for the psx cpu AND gpu emulation
there has GOT to be a way to use the video card to render the scene BUT have it remain completely faithful to original psx output... there just has to be a way...
could be the most difficult thing in the world though... i guess instead of passing instructions from the emulated psx gpu to the the pc cpu, you'd have to pass it to the video driver/hardware... i guess that could be very tricky... i won't even begin to speculate...
but it SHOULD be possible right?

It would be sweet if the graphics of this emu could match that of petes opengl2 plugin

CPU power? GFX? what?) seeya |

(i know lots about computers, really, but i still don't understand, what does the software renderer uses? CPU power? GFX? what?) It uses the cpu, and a lot of it. On top of emulating the playstation, it has to emulate the hardware of a video card. |

well it's not really that bad is it? it's the gpu of an original playstation ffs  wonder if the author has ever considered dual core support... and then that makes me wonder if the framework might already be in place... wonder what kind of speed difference there is between an athlon and p4 |

On top of emulating the playstation, it has to emulate the hardware of a video card. so that's why it started working now... just a month ago i bought a new processor(P4 3.00 800mhz) and it started to work better(before i couldn't play neither in 3d, or OGL, or software)(now i, at least, can play in software =P) thanks seeya |

simplified explanation...:
The output is kinda like a realtime jpeg. everything is drawn on a surface. all the 3d vertex, textures, etc are completely emulated and rendered as 2d on that surface, then it is displayed... then the next frame goes through the same process...the only thing passed to the Video card is the complete surface area (Via direct draw, not D3d) which is displayed again as 2d.
ALL the effects and 3d are 100% emulated and therefore use the CPU.
