I used gamemode because it seemed like a nice performance tool; however it caused performance, stability, and issues (in TeamF2). In TF2, I had irregular frame rates and frame times.
I decided to disable gamemode to see what would happen; because it’s a good idea to test every known factor. I got a consistent frame rate of 60fps and consistent frametime of 16.67ms.
GameMode is a daemon/lib combo for Linux that allows games to request a set of optimisations be temporarily applied to the host OS and/or a game process.
GameMode was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave or ondemand governors, but is now host to a range of optimisation features and configurations.
Currently GameMode includes support for optimisations including:
- CPU governor
- I/O priority
- Process niceness
- Kernel scheduler (
SCHED_ISO)- Screensaver inhibiting
- GPU performance mode (NVIDIA and AMD),
- GPU overclocking (NVIDIA)
- Custom scripts
Constantly changing the behavior of the CPU and priorities can be very bad for stability.
I think games should focus on optimizing their code, instead of relying on third party software.
Game boosters are known to be snake oil; FOSS game boosters are not an exception.
