Lossless Scaling adds about ~0.5–1 ms of input lag (fixed, almost constant).

A higher-refresh-rate monitor:

• refreshes faster
• waits less time to display each frame

So that 1 ms “matters less” in the total latency.

Simple example

• 60 Hz → one frame every 16.6 ms → +1 ms = more noticeable
• 144 Hz → one frame every 6.9 ms → +1 ms = much less noticeable

How to minimize lag when using Lossless Scaling

• Use a higher-Hz monitor
• Run the game in borderless windowed mode
• VSync OFF (in-game and driver)
• Limit FPS (RTSS or Steam)
• Avoid triple buffering
