Ways to fix slow motion with Wan 2.2 + Wan 2.2 Lightx2v 4 step?

Question - Help

So I've bin struggling my butt off these last 2 days tryna get Wan working on my slightly underpowered PC. An RTX 4060 TI 8Gb and 32 gigs of ram, currently working with Wan 2.2 T2V 14B through ComfyUI. After much work I've finally gotten a decent running setup that produces natural looking results using the newer Wan 2.2 based lighx2v 4 step version. I had to swap in the Q3KS GUFFs which seemingly worked well. With 4 steps plus that guff I get great results sometimes in just 5 minutes sometimes a hair more. But I guess a lot of people are having issues with Lightx2v causing things to look like they're in slow motion, which I am too. I've seen people discussing it but they mostly seem to be talking about the WAN 2.1 Lightx2v 480p version. I can't seem to nail down how to fix this without completely tanking my generation times, does anyone have a good solution? Any help or info is greatly appreciated!

PS. Does anyone know if the I2V has the same issues? I havent even opened that yet, but thought I heard that problem doesn't seem to really exist for I2V. Thanks!
