1. The AI Revolution: Tracing the Evolution of NVIDIA DLSS
The journey of Deep Learning Super Sampling began in February 2019 with DLSS 1.0, an ambitious but contentious release. This initial iteration, a predominantly spatial upscaler, demanded per-game training on NVIDIA’s supercomputers and often resulted in a softer image quality marred by noticeable artifacts. Subsequent versions brought incremental yet impactful enhancements: DLSS 3.0 introduced Frame Generation, while DLSS 3.5 added Ray Reconstruction. Now, with DLSS 4.5, NVIDIA makes its most significant architectural leap yet.
| DLSS Version | Key Features | AI Model | Frame Generation/MFG | GPU Compatibility |
|---|---|---|---|---|
| DLSS 2.0 | Improved image quality, generic training, ~2x less overhead, DLAA | CNN | N/A | All GeForce RTX GPUs |
| DLSS 3.0 | Adds Frame Generation (1 interpolated frame per rendered frame) | CNN + Optical Flow | 1x Frame Generation | GeForce RTX 40 Series |
| DLSS 3.5 | Ray Reconstruction (replaces denoisers) | CNN (SR) + AI Network (RR) | 1x Frame Generation | All RTX (RR), RTX 40 (FG) |
| DLSS 4.0 | Multi Frame Generation (up to 3 generated frames) | Transformer Model | Up to 3x Multi Frame Gen | RTX 50 (MFG), All RTX (SR/RR) |
| DLSS 4.5 | Dynamic Multi Frame Generation (up to 6x generated frames) | 2nd Gen Transformer | Up to 6x Dynamic MFG | RTX 50 (Dynamic MFG), All RTX (SR/RR) |
2. DLSS 4.5 Deconstructed: The Core Technologies
DLSS 4.5 is more than a single feature; it’s a cohesive suite of AI-powered neural rendering technologies meticulously engineered to push the very limits of real-time graphics. This iteration marks a fundamental architectural shift, fully embracing advanced transformer models for superior image reconstruction and leveraging the cutting-edge capabilities of the GeForce RTX 50 Series GPUs, particularly their fifth-generation Tensor Cores.
2.1. Multi Frame Generation (MFG): The 6X Performance Multiplier
At the forefront of DLSS 4.5’s performance revolution is Multi Frame Generation (MFG). Building upon previous iterations, MFG now intelligently generates up to three additional frames for every frame traditionally rendered, with the capability to generate up to five frames for a staggering 6x total performance multiplier coming soon in Spring 2026. This is exclusively enabled by the NVIDIA GeForce RTX 50 Series GPUs, which house advanced fifth-generation Tensor Cores and a specialized AI Optical Flow system.

2.2. Transformer Models: Redefining Visual Fidelity
A cornerstone of DLSS 4.5’s visual prowess is the monumental shift from traditional Convolutional Neural Networks (CNNs) to advanced Transformer AI models. These models possess a superior capability to model complex spatial and temporal relationships, calculating twice the number of parameters to gain a far deeper understanding of each frame.

2.3. NVIDIA Reflex Frame Warp: The Latency Game-Changer
NVIDIA Reflex Frame Warp tackles input latency head-on by reprojecting the final rendered frame using the absolute latest player input moments before it’s displayed. In competitive titles like THE FINALS, Reflex Frame Warp can reduce overall input latency by up to 75%, bringing response times down to a mere 14ms.
3. Performance & Compatibility: Who Benefits (and Who Doesn’t)
The theoretical capabilities of DLSS 4.5 translate into truly remarkable real-world performance gains. However, the realization of these benefits is not uniform across all hardware generations.

Critical Alert for Older RTX Users (RTX 20/30 Series)
Our empirical data indicates that these generations can experience significant performance degradation—ranging from 20% to 40% compared to DLSS 4.0—when utilizing the more advanced Model L preset. This is primarily attributed to their lack of FP8 support. Stick to DLSS 4.0 or select “Model Preset M” in the NVIDIA App for these cards.
