Krea 2 Local Generation Slower Than Expected
imataruto · reddit · 2026-07-19
The author tested the local generation speed of Krea 2 on an RTX 4090 and found it underperformed.
- Using krea2rawint8convrot + qwen3vl4bfp8scaled at 1MP resolution with 51 steps, the speed was about 4.19s/it, totaling 3 minutes 32 seconds per generation.
- With turbo enabled and 8 steps, it was about 2.2s/ts, total 16 seconds, which the author still finds slow.
- Peak VRAM usage was about 20GB, which doesn’t seem to be a bottleneck on a 24GB 4090.
- Trying Dynamic VRAM toggle and updating ComfyUI didn’t improve speed significantly, so the author suspects a configuration issue and asks if this is normal and what speeds others achieve with similar hardware.
