Optimizing Local AI Video Models on RTX 3090: Best Configurations
BackgroundCow1411 · reddit · 2026-08-09
A user on Reddit asked for advice on maximizing performance for local AI video generation models (like H3) on a Windows 11 system with an RTX 3090 and 64GB RAM.
The user is currently using CUDA 12.8, NVIDIA driver 566.36, and Stable Diffusion Easy Install (with Sage Attention enabled). Their main dilemma is whether upgrading to CUDA 13.0 for new features is worth the risk of reinstalling and causing video stuttering issues.
