This GPU driver setting cut my frametime variance in half, and competitive FPS games feel completely different now
The article discusses how enabling Nvidia's Smooth Motion frame interpolation feature significantly reduced frametime variance and improved gameplay smoothness in competitive FPS titles. While average FPS is commonly used to measure performance, consistent frametimes have a greater impact on perceived smoothness. The author experienced substantial improvements in frame consistency and low-frame performance in CPU-intensive games like Escape From Tarkov.
- ▪Nvidia Smooth Motion is a driver-level frame interpolation feature that generates intermediate frames using optical flow estimation.
- ▪The feature does not require game integration, unlike DLSS Frame Generation, and works by inserting synthetic frames between rendered ones.
- ▪On a test system with a Ryzen 7 7800X3D and RTX 5080, enabling Smooth Motion increased average FPS in Escape From Tarkov from 87 to 179 and improved 0.1% lows from 49 to 78.
- ▪Smooth Motion is similar in function to AMD's Fluid Motion Frames, both aiming to enhance perceived smoothness through frame generation.
- ▪The author notes that while synthetic frames can introduce artifacts, they are often imperceptible during fast-paced gameplay on a 4K OLED display.
