Fix 1 – Switch the graphics mode
The default graphics mode can be the root cause of this issue.
1. At first, open BlueStacks.
2. Once it opens up, tap on the three-bar menu (≡) and tap on “Settings“.
3. On the left-hand side, tap on “Engine“.
4. After that, set the ‘Graphics renderer’ settings to “DirectX” settings.
5. Finally, tap on “Save” to save these changes.
6. You will be asked to restart the Bluestacks app. Just, tap on “Restart now” to restart it.
Now, close and relaunch the BlueStacks app. Test whether the Engine is working or not.
Fix 2 – Increase the CPU core and RAM
Bluestacks demands quite an amount of processing power and RAM to perform smoothly.
1. At first, open BlueStacks if it isn’t opened yet.
2. Then, tap on the “≡” menu and click on “Settings” to access it.
3. Then, tap on “Engine” on the left-hand side.
4. After that, scroll down through the right-hand pane to the ‘Performance’ tab.
5. Here, set the ‘CPU’ to “Custom“. Then, set the ‘CPU cores’ to a higher value than it was before.
While setting the CPU Cores, do NOT use all the CPU cores for BlueStacks. It will slow down the system significantly. It is suggested that you use at least one core less than the available physical cores.
For example, if you are using a 4-core CPU, set the value of ‘CPU cores’ to “3” or “2“.
6. Once you have set the CPU settings, set the ‘RAM(MB)’ settings to “High (3GB)“.
Just like, CPU core counts, adjust the RAM value according to your system. If you are using a device with 4 GB RAM, we recommend you to set the ‘RAM(MB)’ to “2GB”.
7. Finally, tap on “Save“.
Close and relaunch the BlueStacks emulator. Once it appears, try running some game or app and test whether the engine is working or not.

If you are facing this issue trying to run an only ARM-based app, try to change the ABI settings.
1. At first, open BlueStacks.
2. Then, click on the menu and tap on “Settings“.
