Nvidia has once again redefined what's possible in PC gaming with the announcement of DLSS 4.5 at CES 2026. This latest iteration of their Deep Learning Super Sampling technology achieves what many thought impossible: fully path-traced 4K gaming at 240 frames per second.
What is DLSS 4.5?
DLSS (Deep Learning Super Sampling) 4.5 represents the most significant leap in AI-accelerated graphics since the technology's introduction. It combines four key technologies into one unified solution:
- Multi Frame Generation: Generates up to 3 additional frames for every rendered frame
- Super Resolution 4.0: Enhanced upscaling with 40% better image quality
- Ray Reconstruction 2.0: AI-enhanced ray tracing with minimal performance cost
- Latency Reflex 3.0: Reduces input latency to sub-10ms even at high frame rates
The Numbers Are Staggering
In official benchmarks with the RTX 50 series, DLSS 4.5 delivers:
| Game | Native 4K | DLSS 4.5 | Improvement |
|---|---|---|---|
| Cyberpunk 2077 (Path Tracing) | 24 fps | 240 fps | 10x |
| Alan Wake 2 (Full RT) | 30 fps | 220 fps | 7.3x |
| Black Myth: Wukong (RT Ultra) | 35 fps | 210 fps | 6x |
How It Works: The Technical Deep Dive
DLSS 4.5 leverages Nvidia's new Blackwell architecture with dedicated AI tensor cores that are 2x more powerful than previous generations. The system works in three stages:
- Analysis: AI analyzes motion vectors, depth buffers, and scene complexity
- Prediction: Neural network predicts future frames based on game state
- Generation: High-quality frames are synthesized in real-time
Supported Games at Launch
Over 100 games will support DLSS 4.5 at launch, including:
- Cyberpunk 2077 (full path tracing)
- Alan Wake 2
- Black Myth: Wukong
- Indiana Jones and the Great Circle
- Microsoft Flight Simulator 2024
- Grand Theft Auto VI (confirmed)
Hardware Requirements
DLSS 4.5 requires:
- GPU: Nvidia RTX 50 series (RTX 5070 and above)
- VRAM: Minimum 12GB recommended
- Driver: Game Ready Driver 570.0 or later
Developer Integration
Nvidia has made integration easier than ever with their new DLSS SDK 4.5, which requires just 3 lines of code for basic implementation. The company is also offering free optimization support for AAA titles.
Availability
DLSS 4.5 will be available as a free driver update starting February 15, 2026, coinciding with the RTX 5080 and RTX 5090 launch.
