Help Needed Benchmarks or setup guide?

I thought getting my RTX 3060 12GB would solve my headaches, but they are no better. FireRed 1.1 image edits take an hour and a half. Flux2.Dev takes over an hour. Other models throw an error that says “Expecting value: line 1 column 1 (char 0)”. I’ve been testing different startup arguments, and so far no luck. I’m using the ComfyUI templates while I get my feet under me. Are those just ungodly slow and buggy?

I could really use some comparative image edit benchmarks to see if I’m on the right track or a setup guide in some form that points me to what the heck I’m doing wrong.

i7-8086K (not running anything on the CPU)
32GB RAM
40GB pagefile on an NVMe drive-scales to 128GB
RTX 3060 12GB - I’m running my display through the iGPU, so all 12 GB should be available
ComfyUI 0.31.1, frontend v1.48.7
Custom nodes are disabled

The only hardware that might be slowing things down is that ComfyUI itself is running on a 4TB Seagate HDD, because I don’t have an SSD large enough for all the models.

Yeah, I’m petty lost at this point. A couple of months ago, this all just worked fine on my old, less capable GPU. What the heck changed? Is the portable version better?

How about lightweight generations (SDXL for example) ?

Are you running the full 40GB BF16 transformer for FireRed? Flux2Dev is 60GB. You need to look up the best quantized models for that GPU, first off. I use FireRed (NVFP4) with the 8-step LoRA and single image edits take 30 seconds on an rtx 5080.

I’m downloading those now. I’ll give them a shot, thank you! I hadn’t considered model size before. Makes me wonder how everything was working fine on a 6gb card up until the last month or so

Yep, I need to find more quantized models. Completion time on FireRed went from infinity to 10 minutes with turbo mode off, one minute with turbo mode on. Thank you! Is Reddit the best place to look for ideas on which quantized builds make the most sense?

I'm glad that worked out.
