Performance: resmon, threads, profiling

Every client frame has a budget. At 60 frames per second the game gets about 16.6 ms to do everything, and your script's threads run inside that window. If one script eats 6 ms because of a runaway while true do Wait(0), the player's frame rate drops and the world stutters. This lesson teaches you to read resmon, pick the right thread API, and tune Wait values like a sound engineer tunes a mixer.

You'll learn: resmon, Citizen.CreateThread vs CreateThreadNow, Wait tuning, GetGameTimer for hot loops
Time: ~24 minutes
Prereqs: Lessons 13 (threads) and 14 (server vs client)
Outcome: You drop a client script's resmon cost from about 6 ms to under 0.05 ms without breaking what it draws
