WhySoLaggy

Find out which mod is making your game lag, and who is bombing your room.

Features

Performance Profiling — Find the Lag Source

FPS Monitor: Tracks your frame rate in real time, flags any frame that takes too long
Plugin Timer: Measures how much time each installed mod takes per frame — see who's the slowest
Patch Analyzer: Identifies which specific modified game methods are eating up performance

Room-Bombing Detection — Find Who's Causing Trouble

Automatically monitors network activity in your room and detects suspicious behavior:
- Spawning tons of objects in a short time
- Flooding the network with RPC commands
- Sudden explosion in the number of scene objects
When something suspicious is detected:
- A red alert pops up on the top-left corner of your screen (auto-fades after 12s)
- The log records the suspect player's name and ID number
Observation only — does NOT kick, block, or interfere with anyone. Just records evidence.

Log Files

After your session, open the BepInEx folder in your game directory. You'll find two files:

File	What it records
`BepInEx/WhySoLaggy.log`	Performance data: FPS, mod timing, lag causes
`BepInEx/WhySoLaggy_Abuse.log`	Bombing evidence: suspicious events, suspect players, timeline

These are recreated every time you launch the game, so they won't grow forever.

How to Analyze the Logs

Option A: Give it to any AI (Recommended)

Copy-paste the log content into any AI assistant (ChatGPT, Claude, etc.) and ask:

"This is a performance/abuse log from my game. Please tell me:

Which mod is causing the most lag?

Were there any suspicious players?

What happened and when?"

The AI will give you a clear summary.

Option B: Check it yourself

Performance log: Look for lines with ! or !!! — the number in ms shows how slow it is
Abuse log: Look for lines with ⚠ ABUSE ALERT — the player name and ID are shown right after

Notes

The mod waits 5 seconds after launch before starting, so other mods can finish loading first
Extremely low overhead — won't affect your game performance
Bombing detection is observation-only, perfect for collecting evidence after an incident
