Yes!
Here's my template. There's no audio tracks, but it still causes Reaper to basically hang if I unmute the top folders.

I forgot to mention in the first post, but the problem is mostly in 96kHz. If I go down to 44.1kHz the RT CPU hovers around 60-65%, but if I go back up it gets to over 300%. The FX CPU only gets to roughly the double, as you'd expect.
Also, I've tried changing audio drivers, retitling tracks without unicode, removing sends and removing FX. The only thing that worked is either muting or extracting tracks from their folders. Even having them just one folder deep raises the CPU by quite a lot.
Thanks.
