I use to run ePSXe 1.60 without any problems but now the emulator runs very slowly.

The slowdown even occurs when running only BIOS.

I decided to go with the basic settings:

Plugin: Pete's OpenGL Driver 1.1.75
Author: Pete Bernert
Card vendor: NVIDIA Corporation
GFX card: GeForce2 MX/MX 400/AGP/SSE/forceSW

- 640x480 Window mode
[16 Bit]- Keep psx aspect ratio: off

- R4G4B4A4
- Filtering: 0
- Hi-Res textures: 0
- VRam size: 32 MBytes

- FPS limitation: off
- Frame skipping: off
- FPS limit: 60

- Offscreen drawing: 0
- Framebuffer texture: 0
- Framebuffer access: 0
- Alpha multipass: off
- Mask bit: off
- Advanced blending: off

- Scanlines: off
- Line mode: off
- Unfiltered FB: off
- 15 bit FB: off
- Dithering: off
- Screen smoothing: off
- Screen cushion: off
- Game fixes: off [00000000]

I'm using the Eternal SPU 1.41.

The only major change I made is I'm running Windows XP now as oppose to Windows 98 SE.

Does this emualtor run XP?

I used other video plugins like D3D DX6 and it works okay.

There seems to be an issue with the Pete's OpenGL Driver 1.1.75 plugin in Windows XP.

do you have an AA or AF turned on?

my best guess is that your drivers got fecked on the update from 98 to XP. did you do a reformat, or just an upgrade? most likely if you did a straight update, some of your old 98 drivers are still laying around and that causes problems with XP.
Nope I installed XP on a different partition so I have a dual boot system.

For Windows 98 the older Nvidia drivers are used while XP has the lastest Forceware drivers installed.

I just notice that the new Nvidia drivers does not allow you to change the OpenGL settings while the old drivers could.

What's the difference between D3D DX6 and Pete's OpenGL drivers?
I decided to take the step to degrade my Nvida drivers from 71.89 to the Nvidia Omega Drivers 1.6693 (Forceware 66.93).

The emulator runs perfectly with the OpenGL plugin.

In most cases new would have mean better, but not this case.
