NVIDIA RTX Spark is a new Windows PC platform for AI development, creation, and gaming in slim laptops and compact desktops. Powered by an NVIDIA Blackwell RTX GPU and NVIDIA Grace CPU, it combines up to 128 GB of unified memory with the full NVIDIA CUDA stack and RTX technologies including ray tracing and DLSS 5.
This post covers the following technologies for game developers building on RTX Spark:
- DLSS suite of technologies that boost FPS and improve image quality
- NVIDIA ACE updates for responsive, on-device AI characters
- RTX Kit SDKs for neural rendering, geometry, and character rendering
- NVIDIA Nsight tools for optimizing and debugging native Arm64 and x64 applications
- NVIDIA RTX Branch of Unreal Engine 5.8 for integrating RTX technologies into your Unreal Engine projects
- MotionBricks update for human-character motion
DLSS on RTX Spark
RTX Spark benefits from the full suite of DLSS technologies in supported games, including Super Resolution, Ray Reconstruction, Dynamic Multi Frame Generation, and 3D-Guided Neural Rendering.
DLSS Super Resolution reconstructs frames from a lower resolution input to improve performance. DLSS Ray Reconstruction generates additional pixels to enhance ray-traced scenes. DLSS Dynamic Multi Frame Generation can generate up to 5 additional frames per rendered frame, automatically adjusting the multiplier to maximize smoothness.
The latest NVIDIA app beta also brings a faster Performance Mode (Preset C) for…
