Thx. This will probably be true for all filters that use the GPU. For these filters, there is nothing Avs+ can do about them, aside from using mode 3. Try to place these calls towards the beginning of your script to minimize the performance affect on other filters.
But should there be such a huge performance hit? I have a heavy script which has setmtmodes 2,3 and 4 for fft3dgpu at the end, it runs at 9 fps and fft3dgpu doesn't slow it down at all.

avs+ runs it at 12 fps with mode 2 but if i choose mode3 for fft3dgpu it runs at 6 fps.
However, if i put prefetch before fft3dgpu script seems to run correctly, and at 16 fps.
