I have two a two monitor setup for my computer. I usually put the steam client on the secondary monitor (left monitor) and launch full screen games on the primary monitor (center monitor). When mousing around in Fallout NV (on the primary monitor) I can see links highlighting and various mouse interactions happening on the steam client on the secondary monitor. Probably some Mouse Event propagation that doesn't need to be happening. Could be causing performance problems. Just letting you know, thanks.
