High CPU usage when GUI is open

Cpu usage goes very high (glitchy) when the gui is open and playing back, once closed play back is normal (cpu drops). Must be a programing issue to do with the graphics of vital. I don’t have this problem with any other synth or plugin. Running Windows 10 Studio One Pro latest version.

I am coming across a similar issue, it seems to be exascerbated when creating complex sounds and playing more than three notes together for more than a couple of seconds. However I am running vital on a bog standard computer with 4 GB RAM and without the benefit of a dedicated GPU so will be retesting again once I get a more powerful rig set up in a few days time.
