Anyway that's wrong approach, you are wasting PC/Vita power, you put more work even on router, streaming a 1280x720 video stream instead 960x544.
Remember you can't have better quality on Vita even if streaming 4k from PC because vita is constrained to its native resolution. To understand this better, imagine you have a device with only 2x2 pixels and you want to watch a FullHD movie on it. Also even 2000kbs could be too high for a cartoon like game. I've managed to reduce the latency as much as possible with some additional settings, now when I press a button on Vita in moonlight, visual feedback is almost like when pressing a real hardware button. There are some settings to reduce input lag:
- setup moonlight to 960 544 60 1500 (played PPSSPP Ratchet & Clank with 1500kbs (resolution x10), looks wonderful)
- setup in-game settings if possible to get a solid 60fps
- Nvidia Control Panel: add 960x544 custom resolution, disable in-game VSync and enable Adaptive VSync, set Maximum pre-rendered frames to 1
- Steam client: enable NVFBC from "Settings/In-home streaming/advanced host options", experiment with streaming quality [Fast, Balanced, Beautiful]
- Connect your PC directly to the router with a ethernet cable, so that only Vita will be wireless connected, in the best case scenario this can cut latency by half.
