Nox is a practical Android emulator used to play mobile games on a PC. Sometimes, however, you may encounter the Nox laggy issue like many other players. After analyzing extensive user reports and references, we found the issue can be caused by various factors, including improper system configurations, insufficient disk space, Nox cache, and even antivirus software.
Now, let’s see how to make Nox run faster.
Way 1. Enable VT on Your Computer
If you are running multiple and isolated operating systems on a single server, we recommend you enable VT (Virtual Technology) on your PC. This technology can improve the performance of NoxPlayer.
Step 1. Check if you have enabled the CPU VT.
- Launch Nox to enter the App Center, and then click on Menu and select System info. Then it will automatically check if your PC enabled the CPU VT.
- If the CPU VT is enabled, the NoxPlayer slow issue can be caused by something else. If not, move on to the following steps.
Step 2. Enter BIOS.
- Start your computer.
- When the Windows startup screen appears, press F2or Delete keys to enter BIOS.
Step 3. Enable VT on your PC.
- Go to Advanced > CPU > Virtual by pressing the arrow keys in the BIOS interface.
Tip: The VT is also called Virtualization, VT-X, or SVM in some cases. And it might be included in Configuration or Security instead of the Advanced section.
- Select Enabled for the TV.
- Press F10 to save and exit.
Once done, restart your PC and see if the Nox app player laggy persists.
Way 2. Set High-Performance GPU
Sometimes, the Nox lagging can be caused by improper GPU settings. Here you can speed up the Nox app player by setting a high-performance GPU.
Step 1. Right-click the empty area on your desktop and select NVidia Control Panel.
Step 2. Select Manage 3D settings and go to the Global Settings tab.
Step 3. Select a High-performance NVIDIA processor from the Preferred graphics processor section.
Step 4. Click on Apply to execute the operation.
Step 1. Right-click the Start menu on your desktop, and then navigate to Programs > Catalyst Control Center.
Step 2. Navigate to the Power section and select Switchable Graphics Application Settings.
Step 3. Select NoxPlayer and set its GPU to High Performance.
Step 4. Click on Apply.
Way 3. Update Your Graphics Card Driver
Outdated graphics card driver is also responsible for Nox laggy. To speed up NoxPlayer, we recommend you install the latest graphics card driver.
Step 1. Press Win + R keys to open the Run dialog box, and then type devmgmt.msc in it and hit Enter.
Step 2. Expand the Display adapters category, and then right-click the graphics card driver and select Update Driver.
Step 3. Select Search automatically for the updated driver software option and follow the on-screen prompts to complete the update.
Way 4. Reassign RAM and CPU to NoxPlayer
If the NoxPlayer runs without enough CPU and RAM resources, you may encounter the laggy issue. To fix it, you can follow the steps below to add more CPU and RAM resources to Nox.
Step 1. Launch NoxPlayer and click on Settings.
Step 2. Navigate to the Advanced tab and select Middle from the Performance Setting section.
Step 3. Check the Customize box and set CPU and RAM to higher values. Also, you can input your desired values in the box.

Way 6. Add NoxPlayer to the Exceptions List of the Antivirus Program
If you installed any third-party antivirus software on your PC, the Nox could be blocked by your antivirus. In this case, you can add it to the exceptions list of your antivirus program. For example, you can navigate to Home > Settings > Components > Web Shield > Exceptions to add NoxPlayer to the exceptions list of AVG. The steps may vary depending on your antivirus program.
