Computer cpu


New member

So, I have a late 2013 Imac and I previously had Yosemite and ran many vst's like using Maschine for my production and I used Nexus a lot. I could use 3 or 4 instances of Nexus and my cpu would still be fine. Later I upgraded to El Capitan. After I did that I noticed when I used Nexus just one instance used a lot of cpu usage. I didn't really like how El Capitan was with the cpu usage so I downgraded back to Yosemite and every since it hasn't been the same. When I use 1 instance of Nexus it uses a ton of cpu usage now. It's just not the same as before. Could the upgrade have ruined the usage even with the downgrade.
