Low FPS on packaged Game Problem

Development Rendering
1

Heeeeeeeelp!!!

I’ve packaged a game but can only get it to run at 10 FPS on the target hardware machine.

I’ve tried to follow the steps in this:
https://www.unrealengine.com/en-US/t…nreal-engine-4

I have an execute console command (-FeatureLevelES31 ) that fires on begin play to try and launch the game in mobile preview but to no avail.

My development machine although of a decent spec can run the game at 120 fps, but on the target platform, thats the same as the disc jam tutorial, I’m struggling to get over 10 fps.

What’s going on here guys, I dont have anything that should be causing too much of an issue in the game except a 2k skysphere hdri, can someone please help?

I’m at my wits end.

@Delta1 When you say ‘target platform’, do you mean Intel® Core™ i7-4720 HQ?

If you’re only getting 10fps, there will A LOT you can do to make it run faster…

Did you package for quality or scalability?

Hi Tib,

Sorry my mistake, the target platforms running:
8th Generation Intel Core i5-8350U (Quad Core, 1.7GHz, 6MB cache)
Intel Core i5-8350U Processor Base, Integrated UHD Graphics 620

I packaged for quality, what differences will scalability allow?

Any tips would be life saving honestly.

I massively appreciate any help you may be able to provide.

Cheers,
D.

@Delta1 I think you’ll find if you package for scalability, the engine will automatically adjust to the hardware. Otherwise it’s trying to run flat out.

As far as optimizing your game goes, that’s obviously a huge topic, and there are many youtube vids etc on it ( ie UE4 Performance and Profiling | Unreal Dev Day Montreal 2017 | Unreal Engine - YouTube ).

A really good rule of thumb is to find out what you’re ‘looking at’ ( what is on the screen ) when the fps really dips, that’s your first port of call. Keep adjusting your viewpoint until you know which thing is killing the frame rate and go from there.

Although that rule wont hunt out coding problems, it will find most things.

Good luck :slight_smile:

I GENUINELY APPRECIATE that, THANKYOU so much!

packaged for scalability in the first instance and its only increased fps by 2
