How Do I Read The Profiler

Hello everyone. Im fairly new to the profiler, but im trying to find the reason my game has extreme lag spikes at random… I See a lot of “CPU Stall Wait For Event” In my event name some lasting as long as 50000+ ms which is absolutely melting my cpu.

Im using the SpatialOS for from UE4 with my own custom project

My level is using BSP’s with only 2 textures that are just colors but they arent that many colored bsps only like 6 blocks.

Im using shooter game assets for visualization

Im also using “Competitive Shooter HUD”




Im struggling to understand where to look for my bottleneck problem because I dont know which event my cpu is stalling on.
