I recently noticed that my RTX2070 GPU performance is maxed out at 99-100% when just standing around in Ultima Thule, even when the camera is just pointed at the ground. This is observed in Windows Task Manager, Performance, GPU.
In Limsa, with about 30 players in view, the GPU load is only 50%.
I checked my UPS power display in both locations.
Limsa: 300 watts
UT : 360 watts.
Exit or minimize game: 123 watts
.
So, if your electric bills are a problem, don't AFK in UT. (Or don't AFK anywhere.)
