    I know the hype of this year is about the dual screens and the AMD might be taking over Intel's place in many categories (See Linus's video) in the very near future, I'm sure a lot of people are starting to buy AMD's share after the first day of Computex.

    But NVLink is a new standard that's been going on about since last year, any news on its way to laptops? I know the ASUS Mothership has it but that is way too expensive and heavy, would be really awesome if any OEM make a thin and light laptop with NVlink on it and you can just bring an Inside-out VR headset and can still enjoy VR when you go aboard.

    Am I dreaming way too big?

    What are your thoughts?

    More interested in what AMD can do in the mobile space to be perfectly honest.

    To be thin and light and have two GPUs, I would expect they'd need to be lower wattage (Max-Q), not sure how much VR would really benefit from that. I would like to see a dual card solution show back up in the DTR space, but for high mobility it would be impractical, especially when a single XX60 is enough to run VR in most cases.

    I am a little lost, what does NVLink has to do with inside out tracking? Aside from that, Not sure if many manufacturers want to mess with proprietary tech, and I think stuff like PCIe 4.0 has at least speeds comparable to NVlink 1.0. (sorry I might be out of the loop here).

    The one thing I don't like of current inside-out tracking is that it's less precise than current lighthouse tech, and after experimenting what seems like millimeter accuracy, I wouldn't like a step back. Plus I also feel it has it's disadvantages as it is impractical to have real world 1:1 full distances to travel, so we have to develop something that allows us to move seamlessly in VR without moving in real life the same way.

    Meaning... I don't want to have to play on a literal football track in order to enjoy an adventure game with lots of travel/distance.

    AMD in the mobile category is indeed one of the next big thing.

    As the non-OC GTX1080 seems to be good enough to run the VR, the 90W OC'd RTX2080 Max-Q may be able to run it fine, if that is the case, VR gaming on thin and light laptop seems to be an option.

    What I'm excited about is that experiencing VR during a business trip, if I just need to bring a laptop, a headset, 2 controllers, and then can play VR games in the other place of the earth.

    The Pro and Con of Outside-In and Inside-out are as the followings:

    Pro of Outside-In:
    1. More percise tracking.
    2. Can play in a room without sufficient light.
    Con of Outside-In:
    1. Requires room setup.
    2. Many equipment, bringing them out and play when travelling seems to be impossible for most people.
    Pro of Inside-Out:
    1. With one headset and 2 controllers, you are good to go.
    2. Bring aboard is still a viable option.
    Con of Inside-Out:
    1. Less accurate.
    2. When the controller is outside of the camera range, the tracking sometimes gets lost.
    3. Must play in a bright room for the tracking to work in the best condition.

    NVLink allows you to deliver every thing the VR headset need with a single cable, unlike the current way, at least 2 cables or more are required, wireless seems to be an option but currently only the Outside-In headset is supported.

    What I'm saying is that even though the NVlink isn't a must and can still be compensate by using more cables. But I think if stuff can be done with just one cable, it is always better.

    That makes sense. I mean, it will run on a single 970 just fine so you've got some overhead either way
