Razer Synapse 4: Faster, But Still Nosy

Razer has officially moved to **Synapse 4**. It is no longer in beta, and it is a mandatory upgrade for newer devices like the Viper V3 Pro.

The Upgrade

It is legitimately faster. Razer rebuilt the architecture to be multi-threaded, claiming a 30% speed boost. In testing, it opens faster and crashes less than Synapse 3.

The "Guest Mode" Trap

You *can* use it without an account, but Razer makes it hard.

Guest Mode Trick

If you don't see "Continue as Guest" immediately, you often have to restart the app (or your PC) twice after a fresh install for the button to appear. It's a known "bug" that encourages you to just sign up.

Privacy Warning

Deep dives into Synapse logs (specifically gms-proxy.log) have shown it tracks focused windows and application usage timestamped by the second. If you value privacy, block this executable in your firewall.

Legacy Hardware Warning

EOL Warning

If you are buying an older used Razer mouse (like a DeathAdder Elite) that relies on **Synapse 2**, be warned: Cloud support for Synapse 2 ends **October 28, 2025**. After that, it is offline-only, and you can't sync profiles between PCs.
