Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How do I lock the Editor to 30fps?

Hey there,

I am using a Geforce 470 GTX in the moment to develop using Unreal 4, the card is from 2010 but it still able to achieve quite decent framrates, however when doing this the card goes up to 100% usage and is very loud, what i always tend to do is limit the fps to 30 and reduce settings but i am not really sure how i would go about locking the editor to only use 30 fps?

I also do not want the card to die yet, will need to keep it for some months

On the top right corner of the main Editor window, there is a text box that says "Enter console command here". Type "t.MaxFPS 30" to lock the Editor FPS to 30.

Would be great if this was exposed to the GUI!

Note: In newer versions of the editor, even the console is not exposed in the GUI anymore. See this answer for more information.

Is there a way to change the max FPS for Android mobile?

It seems to be capped at 60 fps.

I'm currently doing the following which works for desktop but not mobile.

alt text

https://github.com/EpicGames/UnrealEngine/blob/master/Engine/Source/Runtime/Engine/Classes/Engine/Engine.h#L1781

 /** Get max fps. */
 virtual float GetMaxFPS() const;

 /** Set max fps. Overrides console variable. */
 virtual void SetMaxFPS(const float MaxFPS);

Thanks man! My laptop was heating up whenever I was using UE4. Now I limited the FPS to 30 and it works cool now.

if you want the editor to open with the default set to MaxFPS = 30:

open: config/ConsoleVariables.ini

 //find: 
 [Startup]
  
 //under it write:
 t.MaxFPS=30

that worked for me thanks! my card was screaming (coil whine) rendering at 120 fps. Now its a smooth 60fps. Not sure why Epic don't cap fps by default to 60.

t.MaxFPS=30 was best option before, but it didn't worked for me in UE 4.17.1 For future readers: You can always use 'Nvidia Profile Inspector' to limit editor FPS.

It's definetly possible, however I don't recommend it as change fan speed by force can damage your card. If you still interested, google app SpeedFan or similar, but be careful.

Oh it wont die. I'm using the engine on a GTX 460 for several months now and it's still alive. One thing you can do though turn real time off when you dont need it.

Good to know :D, i just hate it when the card goes super loud, isn't it possible to regulate fan speed and stuff from a external application?

avatar image Jacky Mar 20 '14 at 05:26 PM

You might find an application like that but i wouldn't suggest lowering the fan speed. Mine gets loud too but i dont mind it. I'm cool as long as my gfx is cool. :)
