Benchmark: Static Grid Performance Test
This benchmark measures McRogueFace's grid rendering performance with a static
100x100 grid. The goal is 60 FPS with minimal CPU usage.
Expected results:
- 60 FPS (16.6ms per frame)
- Grid render time should be <2ms after dirty flag optimization
- Currently will be higher (likely 8-12ms) - this establishes baseline
Usage:
./build/mcrogueface --exec tests/benchmark_static_grid.py
Press F3 to toggle performance overlay
Press ESC to exit
