Quickstart

1. Download
2. Run totsugeki.exe
3. 🐬

Removing Totsugeki is as simple as deleting the executable and launching the game normally.

Features

• 3-4x Speedup compared to vanilla Strive.
• No installation or messing with system files. Just download and run.
• No administrator permissions needed.
• 100% transparent: Sends data bit-for-bit the same as vanilla Strive. No stat or lobby inconsistencies.

Advanced Usage

You can disable any functionality of Totsugeki by adding -no-<feature> as an argument to totsugeki.exe. For example C:\Users\user\Downloads\totsugeki.exe -no-launch will no longer launch GGST.

Valid options:

  -help
        This help text.
  -no-launch
        Don't launch GGST. Useful if you want to launch GGST through other means.
  -no-patch
        Don't patch GGST with proxy address.
  -no-proxy
        Don't start local proxy. Useful if you want to run your own proxy.
  -no-close
        Don't automatically close totsugeki alongside GGST.
  -version
        Print the version number and exit.

The easiest way to do this would be to create a shortcut to totsugeki.exe and add the argument on the shortcut.

The technical nitty gritty

GGST makes a new TCP connection and a new TLS connection every API call it makes. And it makes hundreds of them in the title screen.

Totsugeki solves this by proxying all API requests through a keepalive connection.

What this means is instead of doing 4 round trips (TCP + TLS + HTTP) for each API call, it only needs to do 1 (HTTP only). This shortens the loading time by a factor of FOUR! For example, if you live in the EU and have ~300ms ping to the GGST servers, you usually see something like 300ms * (1 TCP round trip * 2 TLS round trips + 1 HTTP Request round trip) = 1.2 seconds per API call.

This multiplied across all 127 API calls needed to get to the main menu means it takes a whopping 152 seconds (2.5 minutes) to load into GGST.

With Totsugeki, this is brought down to a mere 38 seconds.

This has added bonus of reducing GGST server load, as TLS negotiation is one of the most CPU intensive tasks today.

Thanks to u/TarballX for doing the initial research on why GGST takes so long to connect.
