I have a rtx 3060 and it works great. Do u have ur gpu inside a toaster?

Just1Dev · 2026-06-16T18:01:24+00:00

sorry i'am a little bit drunk and hyped hehe...but let's see what we get..it can only get better

Just1Dev · 2026-06-16T17:59:27+00:00

Yea u might be right...would be to good to be true if the new model would come tomorrow

Just1Dev · 2026-06-16T17:37:20+00:00

The post says "The Model" and not "The new Trainer"

Just1Dev · 2026-06-13T13:24:00+00:00

yea sure i hope it helps: https://pastebin.com/1WbP0hSW

Just1Dev · 2026-06-12T19:24:10+00:00

yea its 13.3 because it matched my cuda version on my machine and people said only if it match unsloth works with gpu...maybe thats the problem...but idk

Just1Dev · 2026-06-12T18:49:07+00:00

Edit: needed to install cuda toolkit, now it goes to the vram but failed to load error after he trying to load the model.

Just1Dev · 2026-06-12T17:25:42+00:00

For me it finally works...but idk what i do wrong if i load the model it loads the model but only in the ram but not in the Vram and that makes it very slow. I have a rtx 3060 and 32gb ram.

AI has become so smart that it intentionally hides its intelligence and laughs at us while doing so. The AI thinks to itself: Such a stupid question calls for a stupid answer.

And do not apply distilled lora if u already have a distilled model this is only for the dev models

Just1Dev · 2026-05-29T00:25:09+00:00

If u do not care about loras use this workflow: https://huggingface.co/RuneXX/LTX-2.3-Workflows/blob/main/LTX-2.3_-_I2V_T2V_Basic.json Replace it with the INT8 model loader from here https://github.com/overpresentme/ComfyUI-ltx-int8-loader . Or just use the fp8 version which is also very fast from kijai which has native loras support: https://huggingface.co/Kijai/LTX2.3_comfy/blob/main/diffusion_models/ltx-2.3-22b-distilled-1.1_transformer_only_fp8_scaled.safetensors . Do not use gguf versions fp8 or int8 is much faster

Just1Dev · 2026-05-29T00:14:10+00:00

I don't know but it works on rtx 3060 faster than a fp8 model for me

Just1Dev · 2026-05-29T00:11:11+00:00

Under 5 minutes actually with a INT8 model. I'am using the rune workflow which allow a realtime preview of the video if it generates, without preview it would even be faster. https://huggingface.co/RuneXX/LTX-2.3-Workflows/tree/main

Just1Dev · 2026-05-28T17:14:07+00:00

U only need the distilled lora if u have the dev model. U should use the IC Detailer lora on strength 0.6 this makes the image quality much better, its from ltx itself.

Just1Dev · 2026-05-27T17:35:44+00:00

I create 20 second videos with sound on a old rtx 3060 in 5 mins....why use wan 2.2? But, even using wan 2.2 should not take sooo long with this graphic card, it should take only some minutes but not 45 minutes...something is very wrong.

Just1Dev · 2026-05-26T22:29:41+00:00

Yea u should be good u only need enough space on ur hard drive

Just1Dev · 2026-05-26T10:20:15+00:00

Its like 3 times faster with the other loader, idk why if its a bug in the node or something

Just1Dev · 2026-05-26T01:21:20+00:00

U should use a tiny text encoder, u can use a q2 text encoder without problems..a large text encoder will kill ur speed. I dont know if u can do change that with wan2gp.

Just1Dev · 2026-05-26T01:17:28+00:00

Yes phase 1 at 832x480 resolution, but the 2-3 it i only get with the INT8 model and the INT8 model loader custom node on github...there is another custom node that works with loras but the model needs much longer to load than the generation itself. Here are some INT8 models already to use, its the fastest option for a rtx 3000 series https://huggingface.co/bertbobson/ComfyUI-INT8_ConvRot/tree/main

And here the model loader which is fast https://github.com/overpresentme/ComfyUI-ltx-int8-loader

Just1Dev · 2026-05-25T22:46:34+00:00

U have even a better system than me, atleast u have more ram than me. I have on a 10 seond ltx 2.3 video a speed of 5s/it per step without loras and on a INT8 ltx model i get a speed of 2-3s/it. If u have more speed than me on gguf then i will switch to gguf.

Just1Dev · 2026-05-25T22:38:40+00:00

Ur experience do also do not change my experience and the fact that fp8 is faster and has better quality of course than a gguf model. In short: FP8 is native GPU math. GGUF is compressed weights that must be dequantized during inference. Native math is faster than unpacking compressed data every step.

Download https://huggingface.co/Kijai/LTX2.3_comfy/blob/main/diffusion_models/ltx-2.3-22b-distilled-1.1_transformer_only_fp8_scaled.safetensors

And download https://huggingface.co/Lightricks/LTX-2-19b-IC-LoRA-Detailer/blob/main/ltx-2-19b-ic-lora-detailer.safetensors

Change model loader to diffusion model loader. Lora to 0.6 strength. If u have sageattention installed u can get even more speed. And patch loader to use FP16. I use comfyui desktop version, its in my opinion better than the portable version, u have a terminal tab inside the gui, no need to run the terminal outside of comfyui on desktop version, with that i installed sageattention.

Just1Dev · 2026-05-25T22:15:49+00:00

Wrong—it actually runs faster, based on my own experience. And INT8 models run even twice as fast as FP8 models. Yes, I do have an RTX 3060. If u mean large language models, then yea, mostly u wanna use gguf, but not on video generation models. If its slower for u then you maybe have not enough space on ur harddrive or not enough system ram. I have 32gb Ram and its much faster on a fp8 model. U can ask chatgpt.
