Frame rate improvements were quite drastic for games like Returnal

Steam beta adds new in-game performance metrics overlay, can show DLSS frames

Valve also explains its somewhat unique methodology for measuring frame rate and CPU usage

While it doesn't offer as much data as advanced tools like Afterburner, Valve's new frame rate counter can display both real and AI-generated frames when DLSS or FSR frame generation is enabled.
