Console Command Cheatsheet

UE5 has hundreds of console commands; perf engineers actually use about thirty. This is the categorized table. For stat commands specifically, see the dedicated stat Cheatsheet. For high-impact CVars with measured frame-time deltas, see the CVar Reference.

Discovery: DumpConsoleCommands Writes every discoverable command + CVar to log. Best "I want to know what exists" command in the engine. Compiled out in Shipping; use Development/Test.

Common gotchas

p.Chaos.DebugDraw.Enabled 1 is required first — every other p.Chaos.DebugDraw.* is silent until that master switch is on.
ke * requires actors to expose UFUNCTION exec/CauseEvent matching the name.
memreport -full writes to Saved/Profiling/MemReports/, not the log.
Stat overlays themselves cost frame time. Run stat none between A/B captures.
