How do I change the refresh rate of ePSXe?

I'm using Pete's openGL 1.75 gfx plugin but it is using a low refresh rate (possibly 60-70hz), and there is no option to change this in the plugin config.
I'd like to have a refresh rate of 85hz. How do I change it?

You can change it via dxdiag but I'm not sure if it works for OpenGL.

dxdiag is direct X diagnostics, i highly doubt DX screws with opengl stuff

Ok, so how do I change it? I was under the impression that you need to add something like "-refresh85" to the command line?

I'd ask this at the official forum only I've been having trouble registering there.

There are two ways:

- Via dxdiag.
- Via Screen Settings.

VIA DXDIAG.

- Click Start then click Run.
- Type "dxdiag" in the open box.
- Click on the last tab and you'll see a row of 4 buttons. Click the last one below.
- There input the desired refresh rate and click OK.
- Exit dxdiag.

VIA SCREEN SETTINGS

- Right-click on your desktop and click "Properties".
- Go to the "Configuration" tab and click "Advanced Options".
- Click "Adapter" tab.
- There you will see a large button below the adapter's info group.
- Choose the desired resolution, color depth and refresh rate.

WARNING: Do not put a higher value that your monitor can't support.
