Watch out, Nvidia: AMD’s FSR 4 tech offers a big leap for PC games – but there’s a catch

AMD's FSR 4 upscaling technology delivers 276 frames per second (fps) on the Radeon RX 9070 XT, a 5% decrease compared to FSR 3's 290 fps. Despite this performance dip, FSR 4 shows significant improvements in visual fidelity and has outperformed Nvidia's DLSS 3 in super-resolution quality. FSR 4 incurs a 37% increase in GPU usage but remains a small fraction of the overall frame time. Currently, FSR 4 is exclusive to RDNA 4 GPUs, and there is potential for AMD to backport it to older GPUs, which could enhance its competitiveness against Nvidia, especially in handheld gaming PCs with RDNA 3.5 integrated graphics.

Forget FPS. Here’s why Frame Time is the PC gaming stat that matters most

Frame time measures the time interval between individual frames displayed on the screen, providing a more detailed view of frame consistency compared to frames per second (FPS). An ideal frame time for a game running at 60 FPS is 16.6 milliseconds per frame, and deviations can lead to stuttering. A frame time graph shows frame time in milliseconds on the vertical axis and frame number or recording time on the horizontal axis, with a flat line indicating optimal performance. Gamers often prefer consistent, lower FPS over fluctuating higher FPS for a better experience. Troubleshooting frame time issues involves examining CPU and GPU utilization and adjusting settings. Keeping video drivers updated is essential, and persistent issues may indicate problems with the game itself, as seen in titles like Gotham Knights and Elden Ring.
