Laggy playback when slowing down the speed/duration of proxy footage

Hello,

I´m editing a 4K footage with proxies. I recorded everything in 59.94fps and created proxies with 1280x720 and 59.94fps.

When I playback the proxy footage, it plays smoothly, but when I slow down the speed/duration of it to 40% (to create the slow motion) it plays very choppy frame by frame. If I disable the proxy, it plays the slow motion smoothly..

Shouldn´t it be the opposite?

I won´t interpret footage because I need to speed ramp some clips and keep others with normal speed.

PC specs:

Windows 10 Pro

Intel(R) Core(TM) i9-10900 CPU @ 2.80GHz 2.81 GHz

32,0 GB RAM

GTX 1660 (not super or Ti)

500GB SSD (currently editing the project and footage on an external HD)

All brand new components, less than an year.

I´ve always used this method, seems like it´s not working right now.

Please, can you help me?

I hope the proxies are Cineform or ProRes/DNx ... and not H.264. The first three would have better playback.

I prefer prores 422lt. They are a tad smaller then Cineform.
