I wouldn't have noticed I didn't have a gpu until I heard my fan spinning hard. Intel graphics has a hard time running a video upscaled to 4k on its own.January's WHQL was the last one the was compatible with the SB 2 from a straight install. I was able to install that one and then it updated to the March Driver. The April update fails.
I was able to force the April Driver but it caused many stuttering issues so I guess I should believe them
