System requirements

A Windows (64-bit) PC.

macOS is not currently supported. Also, on Mac the emulator can only be run in a single thread (one emulator).

If the Nox or MEmu emulator launches and runs, UniMessenger products will work too.

Minimum requirements

A 2 GHz processor (>= 2 cores) with virtualization support, 4+ GB of RAM. The emulator will launch even without a graphics card (open gl mode). To run in fast mode (DirectX), a graphics card is needed. On this hardware, 1–2 emulators will run fine.

To run more emulators at the same time, you need a more powerful PC. Key parameters:

1. Processor — more cores and threads. Roughly 1–1.5 threads per emulator (typically 1 core = 2 threads).
2. RAM — about 1.5–2 GB per emulator.
3. Graphics card, if you want to run the emulator in fast mode (the emulator runs faster).

The estimates are approximate; you must verify them on your specific PC yourself. The main load on the PC comes from the emulators. To check whether your PC can handle it, download the emulators, launch them, and see how many your machine can handle and how. Also check the system requirements on the official emulator sites.

Performance is also affected by the emulator settings:

1. Number of cores — better to set = 1 core, and only increase if you yourself understand why.
2. RAM size — better to set = 1–2 GB. Setting more makes little sense.
3. Emulator resolution and DPI: the lower they are, the fewer resources the emulator consumes. But it's important to make sure that at your chosen resolution and DPI all apps the program uses fit on the emulator screen properly.

If your emulator settings have, for example, 4 cores, 6 GB of RAM, and a tablet resolution, one emulator will consume several times more resources than the same emulator on minimum settings, and you'll be able to run far fewer emulators at the same time. We don't run games in the emulator, so use the minimum in the emulator settings. More: Configuring the Nox / MEmu emulator
