De-duplication forcing interpolation to NOT use GPU on RIFE/VS

[ricliu89]

Using v1.41.0, RIFE/VapourSynth
Interpolating video no de-duplication: uses GPU.
Interpolating video with de-duplication: no GPU use, only CPU.

Regular RIFE works with de-duplication.

Could you provide full logs for this?
Sounds very strange to me. Deduplication is totally separate from CPU/GPU stuff.
