# Cant do this because it breaks desktop portal (create session)!!!.
# For some reason the desktop portal tries to access /proc/gpu-screen-recorder-pid/root from the portal process
# which doesn't work because for some reason CAP_SYS_NICE on a program makes /proc/self/root not readable by other processes.
# The reason portal reads that file might be because portal seems to have a security feature where its able to identify the
# process and if the session token is stolen by another application then it will ignore the session token as it wasn't that
# application that created the session token.

# This is needed to allow gpu screen recorder to run faster than a heavy games fps, for example when trying to record at 60 fps
# but the game drops to 45 fps in some place. That would also make gpu screen recorder drop to 45 fps unless this setcap is used.
