Laptop using both GPU’s?

[Brazo]

I was slightly disappointed with the graphical performance of my 1660ti earlier in an Asus G14 (around 60fps at 1080p medium settings il-2) then I realised it was actually using the Ryzen Vega built in gpu (kudos to that!) rather than the 1660ti). Upon sorting this out the 1660ti gave me a solid 120fps on high settings but afterburner was reporting the 1660ti at 90% and the vega gpu at 20%.

What was going on and why do both gpu’s need to be in use at same time?

Thanks guys that makes sense.

When the vega graphics are on and the Nvidia off the 1660ti shows as 0% so all makes sense!

Have learnt something new so appreciated.
Tbh the vega graphics are actually really good like far better than Intel igpu, almost no need to have a discrete gpu for my uses!
