NVIDIA announced major performance upgrades for RTX AI PCs at CES 2026, delivering up to 3x faster creative AI workflows and 40% faster large language model performance through native NVFP4/FP8 precision support. These free updates transform how creators generate videos, run local AI models, and manage system resources—all without requiring new hardware.
Dual Performance Boost Strategy
The update tackles two critical areas: LLM acceleration and creative AI workflows. Language models like GPT-OSS, Nemotron Nano V2, and Sque 3 308 receive up to 40% performance gains through optimized inference. Meanwhile, ComfyUI users generating images and videos benefit from 3x faster processing speeds when using NVFP4 format on RTX 50 Series GPUs.
NVFP4 and NVFP8 Precision Formats
| Feature | NVFP4 | NVFP8 |
|---|---|---|
| Performance Gain | 3x faster | 2x faster |
| VRAM Reduction | 60% less | 40% less |
| GPU Support | RTX 50 Series | All RTX GPUs |
| Model Support | LTX-2, FLUX.1, FLUX.2, Qwen-Image | Same models |
| ComfyUI Integration | Native support | Native support |
The groundbreaking NVFP4 and NVFP8 data formats slash memory requirements while accelerating performance. These formats work by storing model weights at lower precision without significantly impacting output quality, allowing the GPU to process more data simultaneously. System memory offloading further reduces VRAM pressure by storing inactive model components in RAM.
LTX-2 Audio-to-Video Model
NVIDIA introduced LTX-2 from Lightricks, described as the number one open weights video model available. The system generates up to 4K video content in just 20 seconds, with NVFP8 support delivering 2.0x performance acceleration. ComfyUI’s new RTX Video node upscales 720p GenAI videos to 4K in seconds, cleaning compression artifacts and sharpening edges.
The complete workflow—generating a 10-second video and upscaling to 4K—takes three minutes with NVFP8 optimization compared to 15 minutes using traditional methods. This dramatic reduction enables rapid iteration for content creators testing visual concepts.
Three-Stage Creative Pipeline
NVIDIA showcased a comprehensive video generation blueprint: creators build 3D objects and assets for scenes, set up scenes in Blender to generate photorealistic keyframes, then use video generators to animate between keyframes with automatic 4K upscaling. This modular approach gives artists precise control while maintaining efficiency.
Enhanced LLM Tools and Applications
SLM inference performance improved 35% in llama.cpp and 30% in Ollama over the past four months. These optimizations extend to applications like LM Studio and MSI’s AI Robot app, which controls device settings through conversational AI. The NVIDIA Broadcast app version 2.1 upgraded its Virtual Key Light effect, making it available on RTX 3060 desktop GPUs and higher.
