What is PulzeOS?
Learn how PulzeOS creates a dedicated gaming environment next to Windows to reduce system noise and improve FPS stability.
How PulzeOS improves FPS stability
Understand how a cleaner gaming environment can reduce system noise, improve frame consistency and make games feel smoother.
PulzeOS vs classic FPS boosters
Classic FPS boosters work inside Windows. PulzeOS takes a different approach with a separate gaming environment.
What are 1% lows and 0.1% lows?

PulzeOS vs classic FPS boosters
Classic FPS boosters work inside Windows. PulzeOS takes a different approach with a separate gaming environment.
What is FPS and why it is not the only metric
FPS matters, but frame time, 1% lows, input lag and stability often explain why a game feels smooth or choppy.
What are 1% lows and 0.1% lows?
Learn why 1% lows and 0.1% lows matter more than maximum FPS when judging real game smoothness.
What is input lag?
Input lag is the delay between your action and what appears on screen. Learn what affects it and why it matters.
How to reduce input lag in games
Practical breakdown of what affects input lag: FPS, frame time, V-Sync, CPU/GPU load, drivers and system noise.
Why Rust stutters even on good PCs
Rust can stutter even on strong hardware because of CPU load, RAM, world streaming, servers and Windows background activity.
Why classic FPS guides do not always fix stutters
Some stutters come from system state, background load and frame time instability, not only graphics settings.
CPU bottleneck vs GPU bottleneck: what is the difference?
Learn how CPU and GPU bottlenecks affect FPS, 1% lows and game smoothness differently.
UEFI vs Legacy boot for gaming PCs: what is the difference?
UEFI and Legacy Boot do not directly increase FPS, but they matter for modern systems, Windows 11, GPT and dual boot.
Why Windows background processes affect gaming performance
Background processes can affect CPU, RAM, disk, GPU, frame time and 1% lows while you play.
How RAM affects FPS and stutters
RAM affects stutters, 1% lows, world loading and frame time, especially in heavy games like Rust.
SSD vs HDD for gaming: does it affect FPS?
An SSD may not raise average FPS directly, but it can reduce loading stutters and improve frame time stability.
Why gamers need a separate gaming environment
A powerful gaming PC can still feel unstable when the everyday Windows environment is overloaded with system noise.
