SVP Without Reclock

I'd like to use 24p films with SVP, but currently cannot use without reclock as my display runs at 50hz or 60hz. I have a 2018 OLED TV. I use 50hz nearly all of the time, as reclocking to 60hz causes too much speedup.

Using reclock like this has been fine so far, but now I need to use a 64bit media player, MPC-HC is my preferred, and of course reclock is not available in 64bit. The reason I need to use 64bit is because even without SVP running, MPC-HC 32bit version runs really badly with HVEC 4k content, almost as if the film were playing at half speed. 64bit MPC seems to handle these files OK.

What are my options? Can I somehow improve the performance of 32bit MPC? I only ever use 1.5m interpolation mode in SVP, as I don't like too much smoothness - this works best for me.

I run an i7-2600 @ 3.4ghz, 16gb RAM, Nvidia 1050ti with 4GB RAM on Win 10 64 bit.

Thanks in advance.
