LTX-2.5 vs MiniMax H3 i2v on an RTX 5090: 1080p vs 1344×768 is what 32GB fits

A same-first-frame, same-prompt i2v comparison between LTX-2.5 DFR and MiniMax H3 on an RTX 5090. Notably it's not a same-resolution bake-off: this is what actually fits in 32GB — LTX-2.5 runs at 1920×1088 while MiniMax H3 tops out at 1344×768 since full 1080p doesn't fit. The author asks the community which output looks better.
