Final Fantasy IX combat problem in epsxe

[blobman000]

Lately, I've been trying to run Final Fantasy IX on epsxe. After some configuring, I got it to work for a while, but now battles are not working properly.
Everything runs smoothly, but when a battle occurs, every sound plays twice, and the video slows down and lags.
I'm using Pete's OpenGL2 for my video plug-in with the following settings:
Plugin: Pete's OpenGL2 Driver 2.9

- VRam size: 0 MBytes

Framerate:
- FPS limitation: on
- Frame skipping: off
- FPS limit: 120.0

Compatibility:
- Offscreen drawing: 1
- Framebuffer effects: 2
- Framebuffer uploads: 1

- Mdec filter: on
- Screen filtering: off
- Shader effects: 0/1
- Flicker-fix border size: 0

I'm using the sound plug-in that was provided with epsxe. I've tried other sound plug-ins, but they don't work properly with the emulator.

The game is running off of an official disk.

Thanks in advance for any help you can provide.

It might be your Sound Plugin.

I have a similar issue. In the end, I changed into Pete's D3D Plugin and it works fine. It's too bad since I prefer Pete's OpenGL plugin. Maybe my GPU is not powerful enough.
