This tutorial will take LDPlayer as an example to show you how to fix emulator lag. But no worries, the following top 5 methods are available to fix most emulators.
Enable VT (Virtual Technology) on Your Computer
VT is the abbreviation of Virtualization Technology. Formerly known as Vanderpool, this technology enables a CPU to act as you have several independent computers, in order to enable several operating systems to run at the same time on the same machine.
The Android system of the Android emulator is not the same as the Windows system we use. The Android system on the emulator is run on a virtual "computer". Therefore, turning on the VT will better make use of the resources of the CPU on your computer. This technology does not have a bad influence on your computer equipment.
1. Check Whether VT is Supported or Enabled on Your PC.
Does your computer support VT? Or has your computer already enabled VT and you don’t know? It won’t be a concern if you download LeoMoon-CPU-V to check your computer. It is the only application on the Internet that will help you to detect if your CPU supports Hardware Virtualization. This program is 100% clean. It should work like the following
2. Enable Virtual Technology Right Now
If you find out the VT-x Enabled is not enabled but your PC supports VT, follow the below steps to enable virtual technology:
Firstly, you should restart your computer. Once your computer shuts down and restarts, you need to press F2 or Del key repeatedly to enter the BIOS setup.
In the BIOS, VT section is usually named Intel(R) Virtualization Technology, Virtualization, Virtual, VT-X or SVM. Generally, you can find it in the “Processor Configuration” of the “Advanced” option.
You need to select “Intel(R) Virtualization Technology” and change the setting to Enable. After that, you should press F10 to save the setting and exit from BIOS.
After you enable the Virtualization Technology on BIOS, you can also run LDPlayer to check whether VT is successfully enabled. You can click the Menu button in the top right corner of the window and click “Diagnostic information”. If VT is actually activated, you will see “Enable” in VT option.

Most of the time, the emulator lag should be fixed once you’ve enabled VT on your computer. You will be able to play mobile games on PC using your emulator without lags now. But if this doesn’t solve the problem, you can also try the following methods.
Reconfigure the RAM and CPU Assigned to LDPlayer
If your computer doesn’t support Virtualization Technology or you emulator is still laggy when you are playing mobile games, you can try to reconfigure the CPU and RAM allocated to your Android emulator. It is very easy that you use LDPlayer to customize the CPU and RAM allocation.

Generally, the higher number of RAM and CPU settings means that RAM and CPU will allocate more resources to the emulator so that the emulator will be smoother when you are playing games. But at the same time, this also takes up more space on your computer.
Please note that the number of allocated CPU cores should not exceed the number of physical cores your computer has. Also, you should make sure to leave Windows enough RAM to complete the settings properly.
