Just to add in, I’m still getting some weird lag spikes randomly even with 4.7.2, I thought disabling tutorials fixed it - but it might just have been some temporary fix.
After a ~2-3 hours of usage the RAM usage of UE4 will have risen upwards 6-7GB even with a new, very small project. Leading me to believe there is some sort of memory leak going on - apparently one of the developers of Rats Game had reported the same issue;
I don’t get that bad an experience, but it might be due to the fact he has only 8GB of RAM and I’ve got 16.
More over those lag spikes only occur for me whilst dragging nodes in the EventGraph or whenever the cursor hovers over any object and the editor wants to display a tooltip.
Edit2:
Not sure if there was some hotfix or something pushed through over the night, but the last hour UE4 has been smooth as silk for me. I didn’t do much other than remove a few unused blueprints and staticmeshes*(neither of which were being used in the scene)*.
I will report back later if it stays this smooth or if it starts happening again.
