# DLSS 5

NVIDIA introduced RTX Spark, a Windows PC platform for AI development, creation and gaming in slim laptops and compact desktops, pairing a Blackwell RTX GPU and Grace CPU with up to 128 GB of unified memory and the full CUDA and RTX stack. For game developers it carries DLSS 5 with 3D-Guided Neural Rendering, the locally running Nemotron 3.5 Bolt E4B 4GB in-game agent model, and RTX Kit, Nsight and Unreal Engine tooling with native Arm64 support. The October DLSS 5 model update runs 2x faster than the September version, halves GPU overhead and cuts VRAM use at 4K by 20%.
