Formula
Frame Time = 1000 / min(Refresh Rate, FPS) | Staleness Advantage = (Opp Frame Time - Your Frame Time) / 2
Frame time in milliseconds equals 1000 divided by the effective display rate (lower of refresh rate and FPS). Average visual staleness is half the frame time. The advantage is the difference in staleness between setups.
Worked Examples
Example 1: 240Hz vs 60Hz Competitive FPS
Problem:Compare a player using a 240Hz monitor at 240fps against an opponent on a 60Hz monitor at 60fps in a game where character movement speed is 250 units/second.
Solution:Your frame time = 1000/240 = 4.17ms\nOpponent frame time = 1000/60 = 16.67ms\nFrame time advantage = 16.67 - 4.17 = 12.50ms\nYour avg staleness = 4.17/2 = 2.08ms\nOpponent avg staleness = 16.67/2 = 8.33ms\nStaleness advantage = 8.33 - 2.08 = 6.25ms\nYour movement/frame = 250 x 0.00417 = 1.04 units\nOpponent movement/frame = 250 x 0.01667 = 4.17 units
Result:Frame Advantage: 12.50ms | Visual Freshness: 6.25ms | Impact: Significant
Example 2: 360Hz vs 144Hz Pro-Level Comparison
Problem:Compare a 360Hz setup at 360fps against a 144Hz setup at 144fps with character speed of 300 units/second.
Solution:Your frame time = 1000/360 = 2.78ms\nOpponent frame time = 1000/144 = 6.94ms\nFrame time advantage = 6.94 - 2.78 = 4.17ms\nYour avg staleness = 2.78/2 = 1.39ms\nOpponent avg staleness = 6.94/2 = 3.47ms\nStaleness advantage = 3.47 - 1.39 = 2.08ms\nYour movement/frame = 300 x 0.00278 = 0.83 units\nOpponent movement/frame = 300 x 0.00694 = 2.08 units
Result:Frame Advantage: 4.17ms | Visual Freshness: 2.08ms | Impact: Minor
Frequently Asked Questions
What is screen refresh advantage and how does it work in competitive gaming?
Screen refresh advantage is the competitive edge gained by having a higher monitor refresh rate than your opponent, measured by the difference in frame delivery times. A 240Hz monitor delivers a new frame every 4.17 milliseconds, while a 60Hz monitor delivers one every 16.67 milliseconds. This means the 240Hz player sees visual information 12.5ms fresher on average, effectively seeing the game world in a more current state. In fast-paced FPS games where players move at hundreds of units per second, this fresher information translates to seeing enemy positions that are physically closer to their real-time location. The advantage compounds with other latency factors like input lag and network delay.
How does frame rate interact with refresh rate for visual advantage?
Frame rate and refresh rate interact in a critical way that many players misunderstand. Your effective visual update rate is limited to the LOWER of your FPS and your refresh rate. A 360Hz monitor showing only 100fps produces the same frame timing as a 100Hz monitor at 100fps. Conversely, a GPU rendering 300fps on a 144Hz monitor wastes the extra frames since the display can only show 144 per second. However, higher FPS than refresh rate still provides a minor input latency benefit because the most recently rendered frame is always fresher when the monitor requests the next one. For maximum advantage, your FPS should match or exceed your refresh rate. This is why competitive players lower graphic settings to maximize frame rate.
What is frame staleness and why does it create a competitive advantage?
Frame staleness refers to how old the visual information on your screen is relative to the current game state. On average, the image you see is halfway through its display duration, meaning the visual information is Frame Time divided by 2 milliseconds old. At 60Hz (16.67ms frame time), the average staleness is 8.33ms. At 240Hz (4.17ms frame time), it drops to just 2.08ms. The difference of 6.25ms means the 240Hz player is seeing the game world in a state that is 6.25ms more recent on average. In a game where a character moves at 250 units per second, this 6.25ms difference means the 60Hz player sees the enemy 1.56 units behind their actual position compared to the 240Hz player.
How does refresh rate affect the peeker advantage in FPS games?
Peeker advantage is amplified by refresh rate differences because the peeking player chooses when to initiate the engagement, and higher refresh rates reduce the time between their first visible pixel and the defender ability to perceive and react. When a 240Hz player peeks a corner against a 60Hz defender, the peeker potentially gains up to 12.5ms of additional advantage from the refresh rate difference alone. The defender lower refresh rate means their screen updates less frequently, so the peeker character model may have moved several additional units into view before the defender next frame renders. Combined with network latency and the peeker own reaction time advantage, the total peeker advantage can exceed 80-100ms.
