The editor seems to be freezing every few seconds, for 1-2 seconds, and then works fine again for a few seconds, this keeps happening and it makes it very difficult to navigate and operate anything within the editor.
Hardware specs:
CPU: i7 extreme 990X
RAM: 48GB
MOBO: ASUS ROG Rampage III Black edition
GFX: HD Radeon 6990 (x2 running in crossfire)
I do not suspect it to be a hardware issue, due to me exceeding the minimum specifications.
I was just having the exact same issue. I actually solved it by removing some particle spawns that I had in the construction script of some blueprints. Before I was spawning the particle in the construction script and then toggling the visibility when the player entered a trigger box. Now particles just spawn and destroy on the trigger box instead and editor runs smoothly again with no hitches.
Hey, so there was this weird network error that kept appearing in my Output Log every few seconds, even without the project running. I ignored it for awhile, but then put 2 and 2 together and realized it could be the source for my editor freezing every 2 seconds.
Still have no idea what it meant, but anyone still having trouble should check the comment on this forum here - it instantly solved my issue.
