Sampler Frame Time Debug Graph

One of the most immediate features Sampler adds is an enhanced frame time graph to the standard F3 debug overlay. This graph tracks the last ~2,000 frames to show the consistency of the game's performance.

Graph Components

• Horizontal (X) Axis: Represents time, with the oldest recorded frames on the left and the most recent on the right.
• Vertical (Y) Axis: Represents frame time in milliseconds (ms). Lower lines indicate higher FPS (e.g., 16.67ms equals 60 FPS).
• Horizontal White Lines: These act as benchmarks for 0 ms (infinite FPS), 16.67 ms (60 FPS), 33.33 ms (30 FPS), and 66.67 ms (15 FPS).

Color Coding

• Blue: Time spent in the client tick (simulation logic).
• Green: Time spent in rendering, VSync, and miscellaneous tasks.
• Red Rhomb Markers: These appear at the bottom of the graph whenever Sampler detects a Garbage Collection (GC) run. If a frame spike aligns with a red marker, the lag is caused by memory management rather than rendering or logic.
