A note for Windows 10 users:
Windows manages your graphics card so FractalSoundExplorer.exe will by default run on your CPU, you have to manually specify to run it on your GPU in `Widows Settings > Graphics Settings > Graphics performance preference`. If you have an NVIDIA card you can also have a look trough your NVIDIA Control Panel settings, but if you have a decent NVIDIA card you probably already have gone through and customised your settings anyway.
If you try to run FractalSoundExplorer on your CPU it will probably seem fine until it starts to chug...
