These are estimates, not benchmarks. Your actual frame rate depends on your exact settings, resolution scaling, drivers, and the scene on screen - treat these as a realistic ballpark at high settings, not a guarantee. Lower settings or upscaling (DLSS/FSR) push them higher; maxed-out ray tracing pushes them lower.
