I’m mainly having performance issues when running Android 11. It’s slow and often freezes.
I’m sorry you’re running into performance headaches while using Genymotion with Android 11. Let’s try to pinpoint the cause and get you back to a smooth experience. 🚀

## Quick Checklist
| # | Check | Why it matters | How to verify |
|---|-------|----------------|---------------|
| 1 | **Hardware specs** | Genymotion relies heavily on CPU & RAM. | `System Information` → *CPU, RAM, GPU* |
| 2 | **Host OS** | We only support Windows 10/11, macOS 13+, and recent Linux distros (Ubuntu 22.04+, Fedora 36+). Windows 7 is not supported. | `Win + R → winver` (or `macOS` → About This Mac). |
| 3 | **Virtualization** | VirtualBox/Genymotion needs VT‑x/AMD‑V and nested paging. | In BIOS/UEFI → “Intel VT‑x” or “AMD‑V” enabled. |
| 4 | **Genymotion version** | Older desktop builds may have bugs fixed in newer releases. | `Genymotion` → `Help → About` |
| 5 | **Android 11 image** | Some legacy images have known performance regressions. | `Genymotion` → `Device → Manage Devices → Android 11` |
| 6 | **CPU/GPU usage during run** | High usage can throttle the VM. | Task Manager (Windows) / Activity Monitor (macOS) or `htop` (Linux) |

## Step‑by‑Step Troubleshooting
1. **Confirm host OS compatibility**
- *If you’re on Windows 7, you’re out of luck – upgrade to Windows 10/11.*
- For macOS or Linux, make sure you’re on a supported release.
2. **Check virtualization settings**
- Restart your PC and enter BIOS/UEFI.
- Ensure *Intel VT‑x* (or AMD‑V) and *nested paging* (or “nested virtualization”) are turned on.
- Save and reboot.
3. **Upgrade Genymotion Desktop**
- Go to *Help → Check for Updates* or download the latest installer from the website.
- Version 3.9.0 (or newer) includes performance improvements, especially for ARM‑64 images.
4. **Use the ARM‑64 Android 11 image**
- If you’re still on an x86 image, consider switching to the ARM‑64 variant.
- ARM images are now fully supported on Genymotion Cloud and Desktop (see our 2025 update). They often run more smoothly on modern CPUs with hardware‑accelerated ARM support.
5. **Allocate sufficient RAM & CPU cores**
- In *Settings → Devices*, set the VM’s RAM to at least **4 GB** (8 GB if you have it).
- Assign **2–4 CPU cores** to the VM.
- Don’t over‑allocate; leave enough headroom for your host OS.
6. **Disable unnecessary background apps**
- Close other heavy programs (IDE, browsers, media players).
- On Windows, use `Task Manager` → *Processes* → sort by CPU/RAM and end non‑essential tasks.
7. **Enable “Hardware Acceleration” for graphics**
- In the device settings, ensure *“Enable 3D acceleration”* (or “Hardware‑accelerated graphics”) is ticked.
- If you’re on Windows, make sure your GPU drivers are up‑to‑date (Intel, NVIDIA, AMD).
8. **Check logs for freeze causes**
- `Genymotion` → *Help → Show Log*.
- Look for repeated “Out‑of‑memory” or “CPU overload” messages.
- If you see errors like `Could not start ADB`, reinstall the ADB drivers.
9. **Try the Cloud version**
- If local resources are limited, spin up an Android 11 VM on Genymotion Cloud.
- Cloud instances use powerful GPUs and more RAM than most desktops.
10. **Reinstall Genymotion (last resort)**
- Uninstall, delete residual folders (e.g., `%APPDATA%\Genymobile`), and reinstall fresh.

## Quick Tips
- **Use 64‑bit host OS** – 32‑bit Windows is not supported for Genymotion.
- **Enable Hyper‑V (Windows)** – Genymotion works best with Hyper‑V enabled.
- **Keep your GPU drivers current** – Especially if you’re using the “Hardware‑accelerated graphics” option.
- **Avoid running multiple VMs simultaneously** – Each VM consumes significant resources.
