I used to use it, but i kept throwing a curve ball with some mods, it changes the car files to a X
so its not recognised, and when it fails it messes up the whole of gtl.
all i do now is make a spare file with the the car classes and a locations in them and manually drop the cars in when need for a event and take them back out after woods.
the game fires up quicker and runs smoother this way.
the sounds are put in a different folder and i leave them in all the time
But this tool doeas works good for lap times(sorry a bit off topic)
i do use this to keep a track of my lap times though and it works real good
GTL tool keep track of your lap times (External laptime viewer and statistic tool for GTL & GTR2)
i do have 4 installs of GTL (2 are for testing)
and thats why you will notice on my name i have Rupe wilson3 as a profile name ( the 3 being version 3)
this way all 4 versions i have will work with this tool and keep a record for matching cars and track for events.
but it also keeps a eye on my laptimes in general
Main thing is to keep the sim as light as possible with tracks and cars, it causes less problems with mods this way. There are a few out there that will cause a conflict or need to set up a specific way for them to work or be recognised in game.
