    I'm getting some input lag on Vita Moonlight - do I need to get a 802.11n for platformers to be playable? Or does the vita not support faster Wi-Fi speeds?

    Current Specs:
    GTX 950
    802.11g router, hardwired to PC
    Vita PCH-1001
    Moonlight v0.1.2
    GeForce Experience v2.11.4.0
    GeForce Driver 372.70 (Pre-telemetry)

    (Note: Using the vita as a PC controller has no lag, lowering bitrate from 10000->100 does not have a noticeable effect).

    Vita supports 802.11n, but before you go out and buy a shiny new router, account for a few things first:

    1. How many devices are connected to your router? - The more devices you have and the more active they are, the higher the load on the router CPU
    2. How clear is the wifi channel your SSID resides on? - Try changing to a channel that is low(or ideally empty) on other SSIDs.
    3. Vsync in the PC game settings on? - Turn this off as it increases latency even on the PC side, imagine what this does to a network round-trip for game streaming.
    4. Can you change the game resolution to Vita native? - The less post-processing the Vita has to do, the more responsive your inputs will be. OLEDs are fast, but introducing network trips can be the straw that breaks the camels back here. Try setting to the Vita native res of 960x540, and if that cannot be done easily or at all, 1280x720 will work.

    If you've addressed all these things and input latency is still bad, consider an 802.11n/ac router. Router CPU also matters here too, the beefier it is, the more it can handle without slowing local network response times.

    Hope that helps.

    Thanks, that did the trick! Had to manually create a custom desktop resolution, since Moonlight would crash otherwise.
