How to install RIFE-V2?

I have been using the included RIFE 4.6 on my 3090 using the Tensor-RT engine with performance boost enabled.

It works great at 1080P and below, but is too slow at 4K.

I have heard that RIFE-V2 is fast enough to work at 4K on a 3090.

How do you install it?

I see this:

https://github.com/styler00dollar/Vapou … ter/models

But the content of those model folders there don't appear to match what is currently in my \SVP 4\rife\models folder. If I put them in there and switch to the non-TensorRT engine, they show up in the list of models but MPC crashes when I try to open a video.

Any help? I tried searching through the last few pages of the big RIFE thread but didn't see anything.

Thanks!

EDIT: Secondary question - in that Github repository there are also RIFE V3, V4, etc. Why is V2 all that anyone talks about?
