# Thread priorities
|
|
|
|
Proton supports fine-grained thread priority control using `setpriority(2)` to
|
|
set thread niceness values corresponding to the game threads' Windows base
|
|
priority levels. However, most default Linux configurations don't allow
|
|
individual threads to raise their priority, so some system configuration is
|
|
likely required.
|
|
|
|
It can be configured as a privileged user by editing the
|
|
`/etc/security/limits.conf` file, or using the `/etc/security/limits.d/` conf
|
|
directory, and adding the following line at the end:
|
|
|
|
```
|
|
* hard nice -15
|
|
```
|
|
|
|
Where -15 could be any value between [-20,0] that will correspond to the
|
|
minimum niceness (the highest priority) a thread can get to. The lower the
|
|
value, the more CPU time a high priority thread will get, at the expense of
|
|
others and other processes, possibly making the system less responsive.
