# Unreal Engine 4 QoL Improvements 
Here's some tips to improve your experience using Unreal Engine: 
**&#9632; Show Frame Rate and Memory in Editor** Go into Edit > Editor Preferences and type "Show Frame Rate and Memory" in Search Details, then check it. 
**&#9632; Use New Editor Window (PIE)** Click the drop-down arrow near **Play** and select **New Editor Window (PIE)** - it is more responsive, boost performance and have less input lag. 
**&#9632; t.MaxFPS 300** When playing the active level in editor viewport, it caps your fps to 60. To increase the cap, go to Edit > Project Settings and type "Console" in Search Details field to bind your Console key. Now click Play from the Editor Viewport, click your binded key and write t.maxfps 300 in the newly opened command prompt.) 
**&#9632; r.VSync 0** With your Console key already binded, click Play in the Editor Viewport and write r.vsync 0 to disable Vertical Sync. 
**&#9632; Uncheck FOV Scaling** Go into Project Settings and type "FOV Scaling" in Search Details, then uncheck it. 
**&#9632; Uncheck Mouse Smoothness** Go into Project Settings and type "Mouse Smooth" in Search Details, then uncheck it. 
**&#9632; Change Mouse Sensitivity** Go into Project Settings and select Input from the left column, then scroll down until you see Turn and LookUp inside Axis Mappings, then just change the Scale property. 
**&#9632; Enable Blutilities** Go to Editor Preferences and search for Blutility and check the box to enable it. With Blutilities you'll be able to design several new kinds of tools and workflows based on Blueprints that add new capabilities to the Editor like Scripted Actions (e.g. Bulk Actions), Automation and Editor Widgets. Right-click in Content Browser and select Editor Utilities > Blutility/Editor Widget to start using them.
