I have Arturia Collection 4 and 6 installed both in a win7 (i5 2nd gen, 8 GB RAM) and a win10 (i7 8700k, 16 GB RAM) systems. In win7 everything is ok but in win10 system I have this problem: every time I load Jup8 or SEM and play a note, the CPU load goes up like crazy (150-200%) making these 2 synths unusable. It goes crazy in every DAW that I used it (Ableton Live, Reaper, Studio One) and this happens both in Collection 4 and Collection 6. I uninstalled and installed again and I tried it with different versions also but the problem remains. Is there anyone that had the same problem and is there any workaround? Thanks

 

not sure bro, i just loaded jup8 and played some notes and cpu was like 2% about, maybe check ur system for malware because i just upgraded to 10 from win 7 and everything is kool, my pc is i7 8700k the same with 32gb ram also
