SKK Script Lag detector

SKK Script Lag detector

Suffering from script lag? CC content clogging your tasks? Equip a bell to receive periodic on-screen notifications about script delays.

[Script delay 9.5 seconds 95%]

This is a diagnostic tool not a solution

Feel free to install this mod and give players three Elf-Forged Power Rings: .SKK Script Delay Ring 05 seconds. SKK Script Delay Ring 10 seconds (auto-equip). SKK Script Delay Ring 20 seconds. They will test the potential

The Latency Papyrus Script environment displays messages on the screen (and debug log output) every NN seconds to indicate the load on the game system.

When you investigate the lag, try not to use menus, holotapes and notes as it will cancel the test timer every time you open it as the world will pause.

Remove the ring to stop the test. A spare ring can be made on Chemlab if misplaced and not in stock.

The sweet spot is last, at the bottom of the load order, so it gets the lowest priority to generate worst-case reports.

Papyrus script lag diagnostics

The test starts a script timer for a specified duration. The message on the screen shows the amount of extra time the timer ran and the percentage of the original time that this extra time represented, which represents processing queue - backlog - delay - lag.

Tested with a 10 second timer, a delay of 5.0 seconds means it takes 15 seconds to complete, which is +50% of the time. Note that the Papyrus script subsystem is only allocated a small amount of resources compared to other real-time subsystems, so using tools like the (excellent) Fallout Performance Monitor will not show script resources exceeding commits.

In this type of test, the absolute reported values ​​are interesting, but by themselves they are useless. You need to develop a baseline of acceptable behavior and then compare the results in less-than-stellar gaming experiences to establish problem patterns. Your game may run at 50% script lag, or it may experience choppy results. It's all relative, as Tolstoy advises unhappy families.

Even when running in Zero Mode, the base game script environment ramps up activity as players move, busy cells load while area scans run, and the resident actor AI kicks in. The spike in latency is fine and expected, its continued behavior requires attention.

Determining which mod or script is causing persistent lag is the hard part. If you're on PC, use the debug logs to see what other dumps you have when the persistent lag starts. For Xbox, it's more qualitative: what are you doing, and which of your scripted mods are doing what around the event or location.

Sample debug log output (if enabled):

SKK_SLTMainScript count 1 TimerTime 10.000000 RunTime 13.089001 DeltaTime 3.089001 DeltaPercent 30.890005

SKK_SLTMainScript count 2 TimerTime 10.000000 RunTime 15.100998 DeltaTime 5.100998 DeltaPercent 51.009975

SKK_SLTMainScript count 3 TimerTime 10.000000 RunTime 10.016998 DeltaTime 0.016998 DeltaPercent 0.169983

This is a good profile, plotted in Excel over 24 live minutes, shooting south and then west into busy Academy Square, with 20~40 branches in 5 uGrids with 4-6 radiants.
