GAME CHANGER

Built on the NVIDIA Blackwell architecture, GeForce RTX 50 Series GPUs deliver advanced AI and graphics capabilities for both gamers and creators. NVIDIA DLSS 4 with Multi Frame Generation multiplies frame rates using AI-generated frames, while NVIDIA Studio driver support accelerates content-creation workflows. The RTX 5090 variant in the OMEN 45L carries 32 GB of GDDR7 memory.

RTX. IT’S ON.

The ultimate in Ray Tracing and AI​
​

RTX is NVIDIA's platform for full ray tracing and neural rendering. More than 700 games and applications support RTX technologies, including hardware-accelerated ray tracing, DLSS Multi Frame Generation, and NVIDIA Reflex 2 with Frame Warp, enabling realistic lighting, high frame rates, and reduced system latency.

SUPREME SPEED. SUPERIOR VISUALS. POWERED BY AI.

NVIDIA DLSS 4 is a neural rendering suite that uses dedicated Tensor Cores to boost frame rates, reduce latency, and improve image quality. Multi Frame Generation can produce multiple AI-generated frames per traditionally rendered frame, substantially increasing FPS without proportional GPU load.

COMPETE AT WARP SPEED​

NVIDIA Reflex 2 optimizes the GPU and CPU render pipeline to minimize system latency, improving target acquisition speed, reaction time, and aim precision in competitive titles. The Frame Warp feature adjusts each frame using the latest available mouse-input data before display, cutting perceived latency further.

NVIDIA POWERS THE WORLD’S AI. AND YOURS.

GeForce RTX GPUs include dedicated AI processors (Tensor Cores) that accelerate gaming, content creation, productivity, and local AI development tasks directly on the Windows PC, without requiring cloud offload.

YOUR ONE-STOP SHOP TO ELEVATING YOUR PLAY.

OMEN Gaming Hub provides a single interface for managing performance modes, per-device RGB lighting, and system vitals — including real-time CPU temperature, GPU temperature, memory utilization, and frame-rate monitoring — across all compatible OMEN devices.

COORDINATE YOUR COLOR SCHEME.

OMEN Gaming Hub lets you synchronize lighting effects across compatible OMEN peripherals and system components, including spatially-aware animations and interactive effects tied to in-game events.

CHOOSE YOUR OWN PERFORMANCE.

OMEN Gaming Hub's performance-mode selector lets you switch between preset power profiles — balancing thermal output, fan speed, and clock targets — to match the workload, whether gaming, streaming, or everyday tasks.

NO ONE WANTS TO FLATLINE DURING GAMEPLAY.

A real-time dashboard tracks CPU and GPU temperatures, memory utilization, and other key system metrics during gameplay, letting you monitor thermals and performance without leaving your session.

OPTIMIZER

OMEN Optimizer automatically frees system resources — background processes, unused services — while you play, then restores all settings when your session ends. The result is smoother, faster gameplay with no manual configuration required.

GAME LAUNCHER

The OMEN Game Launcher consolidates your entire game library into one dashboard, compatible with Windows 10 and Windows 11 PCs, so you spend less time searching and more time playing.3
