Ray Tracing & DLSS 3.0
With 3rd-gen Ray Tracing cores and DLSS 3.0, the RTX 4090 achieves real-time ray tracing at playable frame rates.
DLSS 3.0 vs Native Rendering
DLSS 3.0 significantly boosts performance in supported games by utilizing AI-generated frames.
DLSS 3.0 (Deep Learning Super Sampling 3) from NVIDIA is a technology that uses AI-powered Frame Generation (FG) to significantly boost frame rates in games. It works alongside Super Resolution (upscaling) and Reflex (latency reduction) to improve performance while maintaining visual fidelity.
Frame Rate Comparison: With vs. Without DLSS 3.0
The actual frame rate improvement depends on the GPU, game, and settings. However, in general, DLSS 3.0 can double or even triple FPS in supported titles. Below are some comparisons using high-end GPUs (RTX 40 series):
DLSS 3.0 Performance Comparison
| Game | Native 4K (No DLSS, No FG) | DLSS 3 (Quality, FG ON) | Performance Gain |
|---|---|---|---|
