How to monitor FPS?

I typically use RivaTuner which came with MSI Afterburner, but I can not get it to show up in Grim Dawn.

Also, is there a performance thread anywhere of what settings affect performance the most?

If you are playing on Steam, you go to Steam -> Settings -> ingame -> FPS Counter. If you are on GoG, i dunno then.

Steam has a built-in FPS monitor under Settings > In-Game.

Of course that’s no help if you don’t use Steam…

Wow that’s great guys, thanks so much! I had no idea steam had one built in.
