Hi , you are probably right that it’s the GC running, and this is somewhat normal in Development build. To verify your performance, there is a command line that is helpful that should remove that lag : -NoVerifyGC
From the documentation:
-NoVerifyGC Otherwise expect massive hitching in Release builds at least every 30 seconds or so.
This should not be present in Shipping build.
Here is the link to the documentation :
Hope this helps!
