The last update broke NVIDIA DSR and I can no longer play at 4K resolution downsampled to 1080p. It will go black screen and then back to 1080p (the previously selectionned res). If you had your game in 4K DSR before the update then you will be welcomed with an error message saying that your GPU is not available and then game won’t start. You will need to maualy change the res using NVIDIA Geforce Experience and decrease the res to 1080p.
I do not know if the problem comes from the last NVIDIA driver or latest SC2 update as both updated today.
