Dear Friends at Epic,

I was looking through the main rocket engine ini file, and was wondering

  1. how do we set vsync on or off
  2. how do we offer 60 vs 120hz options for different screen resolutions?

Thanks!

Hi Rama,

I haven’t figured out how to enable/disable vSync. I tried this https://rocket.unrealengine.com/docs/ue4/INT/GettingStarted/Basics/SystemSettings/index.html#vsyncsettings but it does not make a difference when put in the DefaultEngine.ini of my project.

For different framerates you can use this:

[/Script/Engine.Engine]
bSmoothFrameRate=true
MinSmoothedFrameRate=22
MaxSmoothedFrameRate=60

Simply set what you want and Unreal will try its best to keep the fps within this margin.

thanks Pascal!

Yes I was aware of the frame rate options.

But I am talking about 60 vs 120 hz in terms of working with the new monitors that can go up to 120 hz :slight_smile:

Hi Rama,

60hz or 120hz is just the refresh rate of the screen you have.

The actual refresh rate of your game built on UE4 will depend on the kind of content you wish to render and how long it takes to actually render it on a given GPU. Their won’t be a checkbox or config setting for this.

Okay thanks Paul (I can give you more exact credit for this if you posted as a separate answer :slight_smile: )
