Update Windows
Install pending Windows updates and restart before you run the Vesper installer.
System requirements
What your Windows PC needs to run Vesper, the PlayStation 5 emulator: 64-bit Windows, a Vulkan 1.3 GPU, and the games you already own. Early guidance — emulation is demanding and results vary by title and build.
Minimum and recommended.
Emulation performance depends on your hardware, the title, and the build. Treat these as starting points rather than guarantees — and check each title's status in the launcher.
| Component | Minimum | Recommended |
|---|---|---|
| Operating system | Windows 10 or 11, 64-bit | Windows 11, 64-bit |
| Processor | 4-core x64 CPU with AVX2 | 8-core x64 CPU with AVX2 |
| Memory | 8 GB RAM | 16 GB RAM |
| Graphics | Vulkan 1.3–capable GPU (NVIDIA / AMD) with current drivers | Discrete GPU with 8 GB VRAM, latest drivers |
| Storage | SSD: room for the app plus your own games | NVMe SSD with room to spare |
| Input | Keyboard and mouse | DualSense over USB or Bluetooth |
Not yet supported: Windows on Arm, macOS, and Linux. Vesper is not affiliated with Sony Interactive Entertainment.
Four minutes of prep.
A little housekeeping goes a long way with early emulation software.
Update graphics drivers
Get the latest driver from your GPU maker's website or app. Vulkan lives in the driver, so old drivers mean broken games.
Make room on an SSD
Leave space for the app, and keep your own games on a fast drive where you can.
Connect a DualSense
Plug in over USB or pair over Bluetooth before launching Vesper. It's the comfiest way to play PS5 titles on PC.
Controllers
DualSense on Windows.
Vesper is built around the DualSense over USB or Bluetooth. Xbox and other gamepads that Windows recognizes work too. If a controller doesn't show up, these usually help.
- Connect over USB first — it's the most reliable way to pair a DualSense with Windows.
- Check that Windows sees it under Settings › Bluetooth & devices.
- Search Windows for "Set up USB game controllers" to test buttons and sticks.
- Try a different cable or USB port, then reopen Vesper.

The download didn't start.
Go to the download page and use the Download Vesper for Windows button. Some browsers ask where to save files first, so check your browser's downloads panel too.
The installer won't run.
Confirm you're on 64-bit Windows 10 or 11, install pending updates, and restart. Windows on Arm isn't supported yet.
My DualSense isn't detected.
Connect over USB first and make sure Windows recognizes the controller, then reconnect it and reopen Vesper.
A game shows a black screen.
Check the title's chip in the launcher — it is Stable. Update your graphics drivers and try the latest Vesper build.
Performance is rough.
Update your graphics drivers, close heavy background apps, and compare your PC with the recommended spec above. Results vary by title while Vesper is in early access, and Vesper makes no frame-rate promises.
Your PC is ready.
