What are you system specs, I use the V5 collection all the time and have not experienced slow loads.
Im using a Dell Inspiron 17" Laptop. Core i5, 16GB Ram, 1 TB Harddrive. Windows 10 Pro updated to latest.
All other plugs I have like AIR Collection ( Loom, Hybrid and all that ), all the NI Stuff Kontakt, Reaktor etc .. all load within say 10 to 15 secs. The Arturia V stuff can take up to 40 secs or more each and then would give me the sonar not responding.
I realise vsts get cached by windows 2nd time around, so faster. But this is all with first time loads into individual tracks. Arturia first time load takes an age, all other plugs load fast and fine.
So .. im not sure it has anything to do with the system spec.
Also the Arturia stuff is coming up in the Virtual Instruments window over right as VST3. NI stuff is coming up as VST2.
