PIE Lag Issue with RHI DirectX 12

Hey guys, I’ve been struggling with an issue where playing in (New Window Editor) PIE lags significantly more than playing in Viewport when using RHI DirectX 12. I have no idea what’s going on, as the DirectX 11 and Vulkan work fine. Anyone have the same issues and solutions?

I have this issue in 5.2 and 5.6
my device: 137k, 5090, 96 GB RAM

Here is the FPS template of 5.6
PIE:


Selected Viewport:


hi, @YURISSMILE
i found and this network plugins can cause delay when they send network package every period , especially when your system disconnected from internet , can you disable then and test again , (maybe you will need disable metahuman also) just disable they temporarily and do some testing try to locate the issues (backup your project first) ,
i want to know this issues too, my laptop is low spec so i want to know whether if it caused by this network plugins

Hi may I ask which network plugin? Also the same issue happened in 5.2, so it’s probably not the metahuman

hi @YURISSMILE

Sorry , I have included plugins names in previous post but were stripped because I encapsuled names inside “[” and “]” ,
here the network plugins you could try to disabled for testing:
Udp messageer
EOS shared

just for testing lag here because some IPC will not work if you disable this plugins for normal work
