... After your post, I went and timed regeneration times on my computer. For me, each re-generation takes 12-15 seconds. And I have an i7-7600U CPU / fast SSD and computer cleaned of all bloatware. Realtracks are on internal SSD, not external HD. Nothing heavy running on background, no VSTs.
Time taken also depends on many aspects beside the processing performance.
- How many tracks
- What is the overall length of the song
- Setting of the Disable Fast Generation option
- Any frozen tracks in the song
etc
So it's difficult (impossible actually) to make an accurate generation time comparison just based on processing performance.
