This page documents small performance tweaks I tested on my Fedora system to improve how games feel while recording. They are all runtime changes, they do not touch the kernel or the bootloader, and they are easy to undo.
The goal is smoother behaviour, better consistency, and fewer small stutters during gameplay. These are simply the steps I followed on my own setup so I could see what difference was made.
Hardware this was tested on
Fedora KDE 43 Kernel 6.17.12
Ryzen 7 5700X3D
32GB RAM
AMD RX 9070 XT 16GB
OBS recording with VAAPI H.264
Your system may behave differently. These are runtime changes.
***Before doing anything***
Do not copy commands blindly.
Read them.
Understand what they change.
If you are unsure, go away and check!
None of this touches the kernel or GRUB.
