I just downloaded UE 5 and experience heavy FPS drop spikes every few seconds.
I am not able to narrow this down any further. It’s not related to the level that is open and happens both inside the editor and while playing in PIE. It even happens in a pitch black blank level that I created freshly.
While the fps are generally stable at 100-120, every 3 to 4 seconds they just spike down to 80 or less with a very disruptive stutter.
Does anyone experience this too or have a solution / lead to a solution?
Thanks in advance!
Curiously, this is actually related to network settings. If you have the same problem and disable UDP transport in the project settings, the stutters should disappear.
If you do not want to tamper with default network settings, disabling the LogMeIn Hamachi network adapter in Windows instead worked for me. Other VPN software might behave similarly.
Does anyone know how this can affect framerate so badly?
