Perf Profiler FS25

This is early development mod, not a standalone software Low or unstable FPS with a big mod list? Before you start deleting mods at random, measure. Perf Profiler times the game's main Lua thread from the inside and writes a clear ranking to log.txt every 20 seconds: - Which MOD costs the most milliseconds per frame - Which FUNCTION inside it (hooks, listeners, vehicle/placeable specializations, game systems) - How much of the frame is Lua at all and how much is the engine (render, physics, loading) - Every SPIKE (frame over 40 ms) with its top contributors, marked as LUA or ENGINE Real example from a 2,489-mod savegame: scripts were only ~4 ms of a ~19 ms frame. The expensive part was somewhere else, and the profiler showed that in 20 minutes instead of a week of trial and error. WHAT IT MEASURES - hook: functions attached by mods (Utils.appendedFunction / prependedFunction / overwrittenFunction) - ovr: functions overwritten by specializations, by name - mod: update()/draw() of mod event listeners - spec: onUpdate / onUpdateTick / onPostUpdate / onDraw of vehicle, placeable and hand-tool specializations - veh: / plc: total update of each vehicle and placeable - sys: game systems (environment, AI, traffic, water, economy...) - frame: total Lua per frame - the scripts vs engine split Every entry shows "self" time (no double counting) and "incl" time (with everything nested). HOW TO USE 1. Put AAA_PerfProfiler.zip into your mods folder and activate it in the savegame. Keep the name - "AAA_" makes it load first, which it needs to catch other mods' hooks. 2. Play normally. The first 20 seconds after loading are skipped. 3. Read the lines in log.txt (Documents/My Games/FarmingSimulator2025/log.txt). CONSOLE COMMANDS (~) ppReport - write a report now ppReset - reset statistics (measure night, rain, fieldwork separately) ppStart / ppStop - resume / pause measuring ppSpike - spike threshold (default 40) ppTop - ranking length (default 35) ppInterval - report interval (default 20) GOOD TO KNOW - This is a testing tool. Measuring costs about 0.5 ms per frame, so remove it when you are done. - It changes nothing in your savegame or gameplay. It only times functions and logs the results. - Measures main-thread Lua. The engine side (render, physics) shows up as "engine" time and ENGINE spikes. - Multiplayer: supported. Like any mod, every player needs the same file if the host has it active. - Full documentation (README.md) with an explanation of every log line is inside the zip.
