Agree with co-commenter, I have never seen anyone who used it for low latency apps say it was sufficient. The target market for displacing e.g. gpus is heavily geared towards low latency.
It might have been OK for mobile games, but then they were just competing with themselves, with an arguably inferior product (if I can't play my mobile game anywhere, only in the vicinity of my house where I already have my high powered rig, what's the point?)
I do think it was an attempt to defeat a very legit, widespread use case to try tk justify pushing thin clients on everyone, glad it failed.
