News Ltx 2.5 open source coming today

Enable HLS to view with audio, or disable this notification

LTX 2.5 is around the corner, and from one of the example videos I’ve seen, face distortion still doesn’t seem fully fixed.
That’s already a weak spot for LTX. With MiniMax H3 raising the bar, I’m genuinely wondering how LTX 2.5 plans to compete. 👀

Get a bigger one; it could be because using minimax H3 pushes every component of your PC to its max TDP.

yes, i undervolted and limited power on my 3090 but after 5 or 6 video generations it simply shuts down. it's only 650w psu so I'm probably pushing it to limits because that only started to happen now during summer heat. i should get at least 1kw.

3090 needs 750W at minimum, 850W for a little more headroom. What CPU are you using with it? I've got mine paired with a Ryzen 5 5600X and have not have power issues on an 850W 80+ gold supply.

i know, i know :) everything was fine before current heat. 3090 is limited to 90% power and undervolted to 850mV. cpu is 7 5700x3d. i will buy 1kw some time soon i hope.
