On launch day, the Asus ROG Ally handheld gaming PC mysteriously had worse performance than it did in my original review, something several other reviewers confirmed.
Two weeks later, Asus is publicly saying 1) that’s not normal, 2) you shouldn’t see reduced performance anymore, and 3) if you do — or if your ROG Ally is having issues with SD cards — you should immediately reach out to Asus technical support.
