This week it's been revealed that the NVIDIA GRID system will officially be leaving its free-for-all this June. That means users of the NVIDIA SHIELD Portable and the NVIDIA SHIELD Tablet will have to start paying cash to NVIDIA to continue using the streaming gaming system known as NVIDIA GRID. That does NOT mean that anyone will have to start paying for NVIDIA GameStream. That's an entirely different monster. That piece of this equation will remain free for the foreseeable future.
