How does one utilize this? Thank you! :)
Beware that you should only do this if FAH is not able to fully utilize your GPU (e.g. because it's a very high-end GPU). Otherwise there is no benefit.

You can give it a try and if your overall PPD increases then keep it set like that. If the overall PPD decreases then go back to one WU at a time.

Just pretend I have no idea what a resource group is or how I create one. ;)

Using Windows client btw. It uses "slots", and when the GPU is used in one of those, you can't re-use it again in another slot. So I assume you're talking about something else...

Edit:
It seems my client software is outdated, and that's why I can't find anything about resource groups... I thought I updated it not that long ago, seems I didn't and then forgot I didn't do it. :P

I'll update in a bit and see how it goes!

You must be using the older v7 client. Try the newer v8 client which is available for Windows as well and is controlled via a web interface instead of a standalone GUI. It uses resource groups instead of slots which work in a different way and lets you do things like run two WUs on one GPU.

Thanks!

Can't remember, but v7 has slots, you can create as many same GPU slots as you want in it.
HAGS needs to be enabled in windows, btw
