Frame gen greyed out and only FSR is in the option to choose.

[UNLIMITED POWA]

Before i could choose the intel ESS or whatever its called as well as FSR and could tick the box for frame gen but now box is greyed out and the Intel option isn't there. But i just remembered i used DX11 on launch for the first time to see how it ran so that's probably it. I'll use default launch next time to see if it fixes it.
