5 Local AI Video Tests on One RTX 3090: What Actually Worked in 2026
LTXV-2.3 distilled, LTXV-2.3 dev, SCAIL-2, Wan 2.1 I2V, and Wan 2.2 I2V, all tested for real on the same hardware. Real timings, real crashes, real quality differences -- not a spec-sheet comparison.
I Reproduced a Viral LTXV-2.3 + RTX Super Resolution Workflow in ComfyUI (Real Numbers)
Step-by-step reproduction of a YouTube LTXV-2.3 text-to-video-with-audio workflow chained into Nvidia's RTX Video Super Resolution node, with real generation times, VRAM usage, and the gotchas I hit on an RTX 3090.
I Tried to Max Out an RTX 3090 with LTX-2.3's Full Dev Model — It Crashed 4 Times in a Row
A real, reproducible OOM crash reproduced 4/4 times running LTXV-2.3's non-distilled dev model on a 24GB RTX 3090: the actual bottleneck wasn't VRAM, it was system RAM, and the GGUF loader path is the common factor.
SCAIL-2 in ComfyUI: Real Character Replacement Test (No Custom Nodes, RTX 3090)
Tested Comfy-Org's official SCAIL-2 template for AI character replacement: swap a person in any video for a reference image while keeping the scene and motion. Real models, real fixes, real output video.
I Animated the Same Frame with Wan 2.1 I2V That LTXV-2.3 Generated From Scratch
Took the exact first frame from a previous LTXV-2.3 text-to-video test and animated it with Wan 2.1 I2V instead -- a real, controlled comparison of two different local video generation approaches on the same RTX 3090.
Wan 2.2 I2V vs Wan 2.1: Same First Frame, Same RTX 3090, Clearly Different Quality
Ran the exact same image-to-video test with Wan 2.2's new dual-model MoE architecture instead of Wan 2.1 -- faster, and visibly sharper output. Real numbers from a local RTX 3090.
Wan 2.2 Video Generation in ComfyUI: Image-to-Video Workflow Guide
Animate any image in ComfyUI with Wan 2.2. Which model size to pick for your GPU, node setup, and motion prompts that actually work.
