VST-ревер нагружает не основной проц, а процессор видеокарты.
This is a proof-of-concept for an impulse reverb processor
running entirely on a GPU.
The program requires a NVidia graphics adapter with at least
a G80 gpu (Geforce 8 series or later) and the latest NVidia
ForceWare driver available to run properly.
Because this is just a proof-of-concept, the GPU code is not
very optimized, the GPU usage is quite high and the plugin
still has a high latency of 8192 samples.
Ideas from people that have knowlege about low-latency
convolution are welcome

I'm sure with a good algorithm,
a GPU could run hundereds of instances, it's a damn fast
co-processor!
...а что дальше?...
