I had to force Unreal to use my integrated graphics card because VR wasn't working with my NVidia card.
When I did this, the framerate dropped terribly and it popped up a dialogue "Frame rate's bad, would you like to lower quality?" Which I said yes to.
Now, I've set it to use my NVidia card again, but it's stuck in this low quality state. It seems to be tied to the engine, not the project. All my 4.9 projects run in this garbage state, but my 4.10 projects are fine.
How can I reset the engine player settings for 4.9?
