How much VRAM was previously required?
- temp_account_32 4y agoI am able to generate a maximum resolution of 512x768 on my 11GB 1080Ti. This seems to use almost 100% of the available RAM.
- frognumber 4y agoThat's weird. I cap out at 512x512 on my 16GB Ampere card. Even stepping down precision doesn't help. I wonder what's different. I use it directly from Python.
- prox 4y agoPerhaps a different kind of chipset that isn’t optimized yet? Just a guess based on other graphics processes.
- MattRix 4y agoYou might have the n_samples (aka batch size) set to a number greater than 1? That basically multiplies the amount of VRAM you’re using. I can generate a 512x512 on my 10gb 3080 no problem (or three 384x384 at a time)
- temp_account_32 4y agoTry the hlky fork: https://github.com/hlky/stable-diffusion https://github.com/hlky/stable-diffusion It measures memory usage as well.
- gpt5 4y agoI can generate a 768x896 pixels image on an RTX 3090, using 23.4/24GB
- moneycantbuy 4y agoHow does the content of the images look compared to the same prompt and seed for 512x512? I ask because when I make 768x896 with M1 MAX the resulting image is less coherent, more noisy, and or has repeating subject matter, nothing really usable unlike 512x512.
- gpt5 4y agoSame here.
- jameshe 4y agoLooks like 10GB in the README[0] for a 512x512 image - though the fork[1] from the repo in this PR claims to be able to work with as little as 4GB VRAM.
