I didn't replace Razer Synapse. I replaced the 600 MB it leaves running.

Описание и применение

ДемонNapse позволяет сохранять пользовательские эффекты подсветки на мыши Razer Basilisk V3 без запуска Synapse, уменьшая потребление памяти с 600 МБ до 2 МБ.

Задача

Razer Synapse consumes 600–940 MB of memory and 30 processes to keep lighting effects running, which is excessive for a few LEDs.

Результат

The daemon allows the Razer Basilisk V3 to maintain custom lighting without Synapse running, reducing memory usage from ~600 MB to ~2 MB and eliminating the need for continuous Synapse processes.

Рабочий процесс

• 1. Keep Synapse running as the editor for Chroma Studio effects.
• 2. When Synapse is closed, the daemon starts, reads log files under %LOCALAPPDATA%\Razer\RazerAppEngine\User Data\Logs, and applies the latest effect definitions.
• 3. The daemon determines the active on‑board profile via a HID register and matches it to a Chroma Studio effect by token overlap.
• 4. It sends per‑LED HID commands to draw the effect frame by frame.
• 5. When Synapse is launched again, the daemon detects it, releases the mouse, and stops its services.
• 6. The daemon runs elevated and stops Razer services while it owns the mouse.
• 7. A check command (demonnapse.exe check) can identify the mouse model, read profiles, and verify LED zones.
• 8. The Rust executable is 603 KB, uses ~2 MB memory, and delay‑loads GPU DLLs for Ambient Awareness.
• 9. The daemon does not render Chroma Generate effects and is not code‑signed.

Доказательства

On my PC that means about 30 Razer processes and somewhere between 600 MB (in the tray) and 940 MB (window open) of memory.

Synapse writes a lot to its own log files, under %LOCALAPPDATA%\Razer\RazerAppEngine\User Data\Logs.

Источник

The daemon reads the logs from the oldest to the newest, so the last definition of each effect wins.

Источник

The first version was Python: 15 MB of private memory and about 0.7 % of one core. The Rust port is a single 603 KB executable using about 2 MB.

It is an independent project, not affiliated with Razer.
