Ever since this recent update, people who rely on WARP to be able to play the game with their friends without hassle, can no longer use the service in order to play the game....
I live in New Zealand...
I'm currently in the country (Outside of town) and have been for the last 3 years. Our internet is on Copper cable... (VDSL Speeds) And we've had two different ISPs in that time
I had the same issue when living in Tawa on 120mb/s down and 80mb/s up, Fiber on a 3rd ISP about 5 years ago...
The moment we upgraded to 950mb/s down and 450mb/s up, my issues disappeared…
I used to work for an Audio/Security company called A.S.S (Audio and Security Solutions) several years ago and had experience with data networks that the company ran in its digital security department...
From my experience and to the best of my knowledge, people who use WARP to resolve connection issues aren't dealing with an ISP problem; it's VRChat's download protocol having an issue with unstable data connections. (Which New Zealand is Famous for)
  • If our connection drops out for a millisecond, VRC's download protocol aborts the download, and you have to restart.
That's where WARP comes in...
WARP acts like an intermediary requester, which keeps the packet requests constant. While your internet stability has its occasional hiccup.
(Think of it like an Uninterruptible Power Supply, but for your Internet connection)
Most modern games have a save/restart condition on their download protocol, so that if your internet drops out while you're loading, it starts back up where it left off, and to the user? - It looks like nothing happened
The reason why the issue disappears when you have faster internet speeds is that interruptions require a lot more interference from external sources to create enough packet loss on a larger data transfer.
  • Thousands of players need WARP to be usable with VRChat... (Else, you sit there in your homeworld/ previously cached worlds,) Trying your best to get a lucky instance where VRC can download the world your friends are in....
[This can take HOURS for a world above 200Mb to download...]
And then when you get in again? You're fighting with your friend's avatars, praying to RNG Jesus that you get a lucky download and can see them in anything, but an error robot...
  • I have a demonstration Video for you on YT, if you'd like a visual example?...
Cheers! :3
