We are aware of an issue where some players may experience stuttering, frame drops, or temporary freezes when moving the mouse in SOS OPS.
We are currently investigating the cause of this issue and working on a fix.
Temporary workaround
As a temporary workaround, try lowering your mouse polling rate to 125 Hz in your mouse manufacturer's software.
Higher polling rates, including 500 Hz, may still cause stuttering for some players. Setting the polling rate to 125 Hz may reduce or completely eliminate the issue.
We are investigating the cause and working on a proper fix, so you should not need to keep this setting permanently.
