Dear Epic,
In 4.11 I was noticing hitches every 60 seconds in my project, and I ran UE4 Profiler and had flat line except oooone spot, and that one spot was a very high hitch of 38ms, and it was garbage collection!
I then created a sample 3rd person project, from the UE4 template, that is BP only.
I changed GC to run every 3 seconds.
I then ran UE4 profiler.
And, in fact, got hitches every 3 seconds.
These hitches cause a visible jump that is obvious in the 3rd person BP template project, and is even more obvious in my physics-based game.
Is there anything that can be done to avoid these hitches from GC?
I dont recall noticing this in prior engine versions, but it is certainly too acute to be ignored.
#Sample Project and Stat file
I’ve included my sample project.
- If you launch game stat will start
- press the END key to end stat collection, then end PIE
or you can simply open unreal front end and open my existing stat file which is included in my download link.
Here is the 4.11.0 launcher release version project:

If you click the .uproject the intermediate folder will be recreated and project should open just fine.
#Please
I really need GC to not cause hitches on whatever interval I choose to run it on…
Any thoughts?
Surely this is affecting everyone if I can repro this in a template project?
I am running a computer that has very high specs, I am certain it is not my computer specs, and the proof is in the UE4 profiler log.
#Thanks!
