I've been playing around with a hybrid graphics configuration on my desktop (Intel iGPU + nvidia dGPU on-demand mode) and while everything works well in-game, I noticed that it seemed to trigger full shader conversion the first time I played games after switching to hybrid mode, even though I was playing on the same nvidia gpu in both cases.
I suspect it's doing shader conversion for the iGPU even though I'm not using it. I have not tested whether it would also do conversion for the dGPU if I didn't have those cached already, or whether it would result in the game running with no cached shaders at all.
