# Optimization

If you need, you can increase the performance in various ways:

* You can decrease the engine scalability. "Epic" is the default setting, you can set it to High setting, which will increase the performance with a low impact on visuals.

* Disable "Use Hardware Ray Tracing when available" or at least set "Software Ray Tracing Mode" to "Global Tracing". This will increase the performance with a low impact on visuals.&#x20;

* You can gain a huge performance by disabling the lumen but it will impact the visuals drastically.

You can disable it from Project Settings or from Post Processing Volume:
