DLSS, FSR & frame generation
Upscaling and frame generation change the performance story — learn what they fix, what they cost, and when latency matters.
Spatial vs temporal upscaling
Techniques like DLSS, FSR, and XeSS reconstruct a higher-resolution image from lower internal render resolutions. Quality modes vary by title; “Quality” vs “Performance” presets trade sharpness for FPS. Always judge in motion, not only static screenshots.
Frame generation
Interpolated frames can lift displayed FPS, but they add latency and depend on base frame rate from the CPU and GPU. Competitive players often disable frame gen; single-player and cinematic titles benefit more.
Interaction with CPU limits
If the CPU cannot feed the GPU enough base frames, upscaling cannot invent responsiveness. See Best GPU for gaming for pairing context.
