Can someone explain "-nologs" to me?

[Riekopo]

I was told that putting "-nologs" into the Arma 3 launch option field will improve performance. Is this true? Does it improve singleplayer or multiplayer performance and by how much?

Hi,

This was maybe true from the Alpha days, before game was released fully. To gather data about how the game performed or about the system it was running on and collected crash reports and such i believe. -nologs will probably not change anything in performance now I think since collection data and tracing isn't needed anymore.
I can't see any performance change when using it anymore anyway.

The game can create logs to make reports. This reports are used by BIS to check errors, and solve tickets from users.
If you use -nologs option you reduce the access to the hard disk and improve the game.

Some. It stops writing entries into the .rpt log file.

Typically not a problem, unless you have a mission or addon that has lots of errors. Sometimes something (usually a script) breaks and this floods the file with entries clogging up I/O operations of the HDD, which in turn dumps fps.

Unless you plan to use the .rpt it wouldn't hurt to run -nologs. You won't gain many fps, but you won't lose any.

No logs is that the the game does not write error logs I believe.. It does improve the performance.

The collection of data and tracing are another valid information source to solve issues inside the game and is using right now by BIS.

Sure it's valid, but didnt think it to the same extent as when running the alpha. Do you know if its done now by default and can be turned of by the -nologs switch?
