Understanding Frame Rate: A Guide to Gaming Performance
Learn what frames per second and refresh rate mean, how the eye and brain judge smoothness, and why steady frame pacing often matters more than a high number.
How Games Run
Frame rate, resolution, GPUs and why games feel smooth or not.

Image upscaling renders a game at a lower size and enlarges it to save work. See how basic and smarter methods differ, and what trade-offs to expect.
Ray tracing simulates how light travels to produce realistic reflections, shadows and lighting in games. Learn how it works and why it demands so much hardware.
Screen tearing splits a picture when the game and display fall out of step. Learn why it happens and how V-Sync and adaptive sync trade smoothness for delay.
What a graphics card does, how it differs from the processor, which parts of a game it affects, and how to read performance reviews without being misled.
What screen resolution means, why more pixels demand more from the graphics card, and how to weigh sharpness against smoothness, with no invented figures.
How the CPU, GPU, memory and storage work together, what a bottleneck is, and how to reason about which part limits a gaming system, without any invented figures.
Lag is a catch-all word for network delay, input delay and low frame rate. Learn how to tell them apart, how each is noticed and what can ease them.
