Pixelwave Flux: Low-VRAM Image Upscaling in ComfyUI
Let’s be real—most high-res image tools demand serious hardware. But Pixelwave Flux caught my attention because it actually works on machines with as little as 2GB VRAM. I didn’t expect much at first, but the 8x tile upscale method surprised me.
Here’s the thing: Normal upscaling often turns images into a blurry mess. Pixelwave Flux splits the image into smaller tiles, enhances each one separately, then stitches them back together. The result? Sharper details without the usual artifacts.
I grabbed the PixelWave_FLUX.1-dev_03 model from Hugging Face and paired it with the 4x_NMKD-Siax_200k.pth upscaler. The combo handled 8x upscales smoothly, even on my older laptop. If you’re curious, the models are linked below—just drag them into ComfyUI and connect the nodes.
What actually happened when I tried it? The workflow kept VRAM usage under 2GB, which is wild for an 8x upscale. No fancy hardware needed.
