This is a possible solution for sound and FPS problems. Esp with SoundBlaster.

I have looked at the forums for my problem but have no solution has worked, and the creators seem to not know what the problem is. I have used all Plug-in combinations, options and defrag with no change.

While playing any game while using P64, at anypoint when the amount of sound increases (not volume about amount) the games sound begins to stutter and then the FPS drops to about 30-35. However if the P64 is played without sound then the FPS is steady around 57-60, even on Perfect Dark and Zelda:MM!

It has to be said that I can run both Nemu64 and 1964 with no emulation problems bar one (Blastcorps won't work on Nemu64?!). I have also tried out the plug-ins that came with the P64 service pack! with these emulators. No problems arose.

To be frank, the designers were considering that the people who had this stuttering because of slow processors, but how can someone with a P4 1.0 run more games than someone with a P4 1.6.

THIS IS A PROBLEM THAT I HAVE SEEN BEFORE.


History lesson, a couple of years ago I decided to try a few old Pre-1996 DOS games, as some of you may know these games are very hard to run on Winxp. However one of the main reasons for this is due to the computer running the game TOO FAST.

When certain games are sped up, the sounddriver can not handle the information. This leads to the sound card trying to catch-up which leads to the stuttering. Since the sound driver requires more data, more processor usage is needed and the game slows down.

This happens on, example, X-COM Apocolepse.
THIS APPEARS TO BE THE SAME PROBLEM ON P64.

Due to this problem, the makers of "VMWare Workstation" (an O.S. emulator) created and released the VDMSound.

This emulates the sound, and no it does not work for P64. At least not for me. Probely due to the fact that P64 is Win based (is it 32bit?)

How ever I do feel this is the problem, as such another solution may work. One of the older work arounds was to slow down the game so the the sound card is not over worked. There are programs on the net that can slow down programs by percentage, one is called MoSlo.

However it is no longer free-to-use. But an older version can be downloaded.
Another is CPUKILLER, but I have not tried it yet.

So, I like to ask the developers to add an option to run the emulator at ONE SPEED, NO MATTER the processor speed. Unlikely since the last up-date was so long ago. But who knows, maybe this thread will make them look at some of the problems in a new light.

On last fact, the problems with games running to fast are mostly associated with the SoundBlaster family.

Well you have the right idea with the speed being the issue of the N64 sound stuttering. The issue is though that the N64's CPU does both the graphics and the sound (there is no seperate sound chip) and unless they are perfectly in sync stuttering occurs. This has been a tough obstacle with the emulation and the programmer's are figuring out how to work around the issue. The next version of 1964 is supposed to have a really good sound plugin and a lot more compatibility, it's due out anytime so when that comes out give it a try.

Good to hear, as I said I have no problems with 1964.

But I believe that Project64 sovles a few grahpical problems that the others do not.

But is 1964 and project64 have any code that is simular, they appear to have simular GUIs? I think that P64 uses a unique way to emulate the n64. So if that istaken up to much percentage in the emulator, maybe its enough to effect sound?

And even though Nemu works fine, I cannot seem to change plug-ins for sound or (importantly) controller.

Guess if i want it perfect i'll dig out my n64 from my brothers room :evil:

I don't think the SoundBlaster has anything to do with it, especially since you have the newest drivers installed. My SB Live Value (cheaper version of your card) works great with just about all games (including PD and Zelda MM) with Jabo's default audio plugin. Sometimes I check the audio sync (audio settings) to get better sound. The problem, as already said, is that your CPU is strugging to run certain games at full speed, which causes audio problems.
