I have a large mp3 collection (more than 100,000 mp3s). When I use content (precise) at 70% the program almost stalls when it goes over 15,000 files. It becomes extremely slow even though I have an i7-2600k.
The other question/problem is the video card acceleration. My card is a HD5870 Vapor-X. It shows in the OpenCL window as AMD Accelerated Parallel Processing - Cypress. What happens is I don't notice any difference in speed with or without it activated.
