Ai Variability Parameter
Posted Mar 10 2018 - 02:14 AM
Can anyone explain how the 'variability' parameter works in the driver.ini files?
Searching the forum, it seems like it introduces a random factor to AI drivers lap times, but not all driver.ini files use the parameter. Even when 'variability' isn't used, the AI lap times still vary. Can anyone please explain what it adds?

Nigel added this feature some time around 2007 or so...certainly before 2009 when he left GPL so that is why older mods didn't have a variability setting. AFAIK, you can add a variability setting to older mods, but its use depends on whether the mod's physics set permits this feature. Mods since 2009 do.
As you noted, even without a variability setting, the AI lap times have a bit of randomness anyway.

Now the gplc67.exe physics set may include the code. I don't know where to look for the code in the physics set so don't know if the variability line has any effect with that. You could test it yourself by changing the variability line value.
