NVIDIA DLSS 4.5 Unveiled: 6x FrameGen, 240 FPS Mode

• Key Takeaways:
• NVIDIA announced DLSS 4.5, promising improved image quality alongside major Frame Generation upgrades.
• New FrameGen tech can multiply frame output up to 6x in supported titles, according to NVIDIA.
• A dedicated 240 FPS Mode targets high-refresh gaming and competitive play on compatible systems.
• Availability and exact system requirements will depend on developer support and compatible RTX GPUs.

What NVIDIA is announcing

NVIDIA has introduced DLSS 4.5, an incremental update to its Deep Learning Super Sampling suite that focuses on image quality and advanced frame generation.

The company highlights two headline features: a significant boost to FrameGen (frame generation) that it says can reach up to 6x, and a new 240 FPS Mode aimed at high-refresh displays and competitive gamers.

6x FrameGen explained

FrameGen uses AI to synthesize frames between rendered frames to increase perceived frame rates without the GPU doing full rendering work for every frame.

NVIDIA’s claim of up to 6x suggests more aggressive temporal and AI interpolation techniques compared with earlier DLSS generations, translating to much smoother motion on supported titles and hardware.

240 FPS Mode: high-refresh gaming focus

The 240 FPS Mode is designed to sustain very high frame rates on compatible GPUs and monitors, prioritizing frame pacing and latency for competitive play.

This mode will be most relevant to players with high-refresh panels (240 Hz or higher) and systems that can take advantage of FrameGen to hit those frame-rate targets consistently.

Image quality improvements

Beyond raw frame counts, DLSS 4.5 emphasizes improved image fidelity—NVIDIA states quality is higher than previous versions while still delivering the performance gains gamers expect from DLSS.

That balance is crucial for players who want both sharp visuals and smooth, low-latency gameplay.

Compatibility and system requirements

NVIDIA has not published a complete compatibility matrix in this announcement; historically, DLSS upgrades target RTX-series GPUs and require game developers to integrate the new SDK.

Expect DLSS 4.5 features to roll out first in titles that already support DLSS and in systems with modern RTX GPUs.

Developer adoption and availability

NVIDIA will need developer integration for games to expose the new FrameGen modes and 240 FPS option. Adoption speed will determine how quickly players see the benefits across the catalog.

Watch for follow-up patches and developer notes that specify how to enable the new modes and any quality/performance trade-offs per title.

Bottom line

DLSS 4.5 targets both visual quality and competitive performance by combining better upscaling with a much more aggressive FrameGen and a new 240 FPS Mode.

Gamers should look for developer updates and driver releases from NVIDIA to learn which titles and GPUs will get support first.
