You mean in the nvidia programm settings? It's already set on my graphiccard. There is a second option, but its the same. And i tried both, nothing helped.As I said, in the performance tab the graphiccard spikes up to 100% and stays there, so I assume the GPU is in use when playing GW2, they just dont seem to like each other. Or is there another option you are talking about? Yeah, what I meant - make sure it's actually running on Nvidia, not integrated. But seems you're all set, so really dunno the issue, weird
