CES 2026 has just delivered massive news for PC gamers. NVIDIA officially unveiled DLSS 4.5, a technology that promises to redefine performance boundaries with a staggering 6x frame generation capability.
If you thought DLSS 3 was a game-changer, the leap to 4.5 is generational. With the introduction of the 2nd Gen Transformer AI model and Dynamic Multi-Frame Generation, we are looking at 4K path-traced gaming hitting 240Hz+ effortlessly.
What is the DLSS 4.5 2nd Gen Transformer Model? (And Why It Matters)
The heart of DLSS 4.5 isn't just about speed; it's about clarity. NVIDIA has introduced a 2nd Gen Transformer AI model that changes how upscaling works.
Unlike previous iterations, this model is trained and runs inference directly in linear space (the game engine’s native environment). By utilizing FP8 precision data via the Tensor Cores on GeForce RTX 40 and 50 series GPUs, NVIDIA has doubled the inference throughput.
Key Visual Improvements::
Superior Detail: Better lighting, sharper edges, and more accurate texture details after upscaling.
Reduced Ghosting: The new temporal stability algorithms significantly reduce the visual artifacts often associated with fast motion.
Availability Note: The 2nd Gen Transformer Model isn't locked behind a paywall of new hardware. It supports RTX 20, 30, 40, and 50 series GPUs, meaning almost everyone gets a visual upgrade.
Unlocking 6x Frame Rates: Performance Gains vs. Thermal Throttling
This is the headline feature. While DLSS 4 capped out at 4x frame generation, DLSS 4.5 pushes this to 6x. By leveraging the improved efficiency of the 2nd Gen Transformer model, the system can now generate 5 intermediate frames for every 1 natively rendered frame.
The Hidden Danger: High FPS and Overheating
Pushing 6x frame rates allows you to fully utilize 360Hz monitors, but it also means your GPU will be boosting aggressively to maintain that throughput. As we know, the number-one cause of sudden FPS drops is excessive heat. When your GPU gets too hot (typically 80–90°C), it throttles performance.
To sustain these high frame rates without stuttering, you need a chassis that prioritizes intake. We recommend upgrading to a high-airflow case like the darkFlash DY460, which features louvered side panels specifically designed to maximize cold air intake for your GPU.
Dynamic Multi-Frame Generation: Achieving Stable 240Hz 4K Gaming
One of the smartest features in DLSS 4.5 is Dynamic Multi-Frame Generation. Instead of a fixed multiplier, the AI continuously monitors the gap between your GPU's raw performance and your monitor's maximum refresh rate. It effectively "fills in the blanks" in real-time.
The Result: In 4K resolution with full Path Tracing enabled, NVIDIA demonstrated games running at stable 240 FPS by dynamically shifting between 3x and 5x generation rates.
Power Stability for Next-Gen GPUs
Generating frames at this velocity requires stable power delivery. Sudden spikes in GPU usage during intense gaming scenes can cause system instability if your PSU isn't up to the task.

If you are planning to upgrade to an RTX 50 series card to utilize these features, ensure your rig is powered by a high-wattage unit like the darkFlash PMT Series 1050W+ PSU (Cybenetics Platinum Certified) to handle the transient spikes of next-gen GPUs.
DLSS 4.5 Release Date & Supported Graphics Cards
NVIDIA is rolling this out in two phases. Here is what you need to know to get your system ready:
Phase 1: Available Now (Visual Upgrade)
You can experience the 2nd Gen Transformer Model immediately via the NVIDIA App Beta 11.0.6.
How to enable: Go to the DLSS adjustment interface in the app and select "DLSS Override - Model Preset M."
Supported Hardware: RTX 20, 30, 40, and 50 Series.
Phase 2: Spring 2026 (Performance Upgrade)
The massive 6x Frame Generation feature is scheduled for release in Spring 2026.
Supported Hardware: Exclusive to GeForce RTX 50 Series GPUs.
Game Support: Over 250 games currently supporting multi-frame generation will be compatible.
Conclusion: Is Your PC Ready for 2026?
DLSS 4.5 is poised to make 4K/240Hz gaming the new standard for enthusiasts. However, software is only half the battle. To maintain those frames, your hardware environment—specifically airflow and power stability—must be top-tier.
Whether you need to improve your case airflow to prevent thermal throttling or secure a stable power supply for an RTX 50 upgrade, darkFlash has the components to ensure your rig keeps up with the software.
