Crono Cross sound/Vsync problem

Mattias · May 30th, 2003

I was wondering if someone here could help me with this. I'm playing Crono Cross on ePSXe, using Peops GPU and Eternal SPU.

Everything works perfectly, except for one thing; if I enable Vsync, the graphics look fine, but the sound slows down sometimes (like when I enter the menus, or when I talk to people). If I on the other hand turn off Vsync, the graphics (scrolling) don't look good, but the sound is flawless.

Is there any way to make both work, or do I have to choose?

Oh, yeah, I'm running the game from an ISO image. I dumped it because I think I've heard somewhere it would help with sound problems like these...

could you please post tour pc specs, the plugins you r using, and their configs? It'll make easyer to help you.

Oh. Sorry. I'm using:

AMD Athlon XP 1600+ (1.4 Ghz I think)
256 MB RAM
Nvida MX400 with 64 MB video RAM
Windows XP

Yes. There was no change.

Hey, I seem to have solved the problem myself! I tried changing 640x480, 60 Hz, to 640x480, 85 Hz, and that did the trick! Now both sound and graphics run fine (without vsync).
Should have tried that before I asked... Thanks anyway!

Well on my 700Mhz Duron i get no slowdowns/cracks in audio with this setting:
SPU: SPUAsync Wait
GPU: Frame limit OFF

Of course i can't use Full VRAM primitives = no motion blur for me

Mr. Killjoy · June 1st, 2003

don't use SPU async...
else use Peops SPU, it's async mode works better than eternal's one with me

Why, if i may ask?
For me atleast the setting i posted above works best by far.

PS. anyone with a ~similar setting with me? How does resolution change affect your psx emulation? Since i can't see any change between 640x480 32bit and 1280x1024 32bit ? wtf? Only thing that makes difference is the framebuffer access settings...
