After upgrading to 515.48 I had a weird bug in Horizon Zero Dawn, which has otherwise been rock-solid on my 3070: opening the map and going back to the game resulted in the right third of the screen being black with some oily rainbow effects.
I downgraded with eos-shifttime and everything is fine for now.
edit: if I can’t wait until the next nvidia version to upgrade my system, I’ll try and see whether the LTS kernel makes any difference.
