As gamers ourselves, we would hate it if we kept all of our users from playing their favourite games let alone using their PC.
This is why you have different GPU Utilizations to chose from. As GPU performance varies between our users, you will have to test which mode (Low, Medium, Full) works best with your GPU and the game you wish to play while running GFS.
During AFK / idle time the GFS engine will automatically return to full speed, regardless of mode selected
Many of our users can play games like WoW while using GFS on low GPU usage without impacting their game experience. This means they can farm for WoW playtime, while playing WoW - how cool is that?
Users with powerful GPU's such as a GTX 1080 may find that they can run the engine on Full and still be able to use the PC normally, stream videos, etc.
Keep it running while watching YouTube or your favorite Twitch-Streamer - some users reported no impact even on medium usage.
