Render Times
What kind of render times are you all getting with the new LTX2.3 model. I have only been using the full-dev settings.. I mean, I think.. It's hard for me to keep track of what is what when it first comes out, and now there's probably a bunch of fp-8 and GGUF stuff that I don't even know about yet. But what kind of times are you getting? What is your setup?
96GB RAM, RTX 5090+RTX Pro 6000
LTX-2.3-22b-Dev, Two-Stage Pipeline
1920x1088
222 sec for 241 frames.
64GB Ram, RTX 5090
Dev FP8, 8 step, 1280X720
82 sec for 481 frames.
Going less frames only saves 2-5 secs since most the time is loading the model.
564sec for 961 frames

@bmgjet Holy crap!!!... that's insane!!!.. Im probably gonna have to check out those FP8 models.. Wonder how much the increase would be @1920x1080 ...
547sec for 481 frames at 1920X1080
547sec for 481 frames at 1920X1080
Nice!!!... I'm gonna grab that FP8 file tonight and check it out.. How does the quality hold up?
Not checked.
LTX-2 I couldn't tell the difference between the normal and fp8 version so went straight to fp8 this time.
@bmgjet Daaaang!!... The FP8's are significantly faster.. well, I mean they're all fast compared to anything else.. And, the quality does seem to be damn close to the Full-dev. Almost a minute faster on the first run, and about 25sec faster on subsequent runs.. and yeah the quality looks just as good.. like, you know something is different, but couldn't really figure out what if your life depended on it.
If your on a blackwell GPU then you can also use the NV4 when that gets released. Which is meant to be a 200-300% over FP8 for 10% quality loss.
On the LTX-2 model it was about 280% faster for my work flow making long duration videos. Slow action stuff you couldn't tell the difference. High action you'd notice movement artifacts which id call more then 10% worse.
Well that sounds insane... 200-300%... I could only imagine it would be nothing but artifacts.. Lol.
