FAQ
What runtime performance impact does ACE have on my game?▼
ACE uses GPU-accelerated inference to minimize overhead. On modern GPUs, the AI models run in parallel with rendering, typically using less than 5% of GPU resources.
Can ACE work offline or is cloud required?▼
ACE offers both local and cloud modes. For full offline capability, some features like large language models may require a high-end GPU. Cloud mode offloads processing to NVIDIA servers.
Does ACE support custom character meshes and animations?▼
Yes, ACE works with any standard humanoid character. You can integrate your own skeleton and blendshapes, and the system will adapt the animation output accordingly.
