    Having the same experience on 2017 15″ MacBook Pro Quad 16GB RAM.

    I am having the same issue with the full version. In Logic Pro X using the integrated graphics the Tap to Find is jerky. Also the CPU usage on one thread runs very high (75-80%) and occasionally goes to 100% causing pops and cracks. When switching to the discrete graphics (Radeon 560X) the CPU usage goes down and the lag is gone. This only happens when I open the plugin, so the drums are displayed. If I close the plugin the CPU usage comes down, which leads me to believe that the issue is with the drum rendering optimisation. The drum graphics do not look like super eye candy, so I would not expect that you would need too much GPU power. Unless somebody argues differently, I believe the issue is code optimisation. I am running this on latest gen Macbook Pro 15″ with i9 8-core CPU and 16GB of RAM.

    What latency are you running your audio buffer at? Lower buffer equals lower latency but higher cpu usage.

    I am running at 128 samples. But the issue is not CPU usage during live playing. It only starts to be an issue when I open the EZdrummer GUI and the drums are diplayed. If the GUI is closed the CPU usage is half – there is only one thread that seems to handle EZD2. Hope this makes it clearer. Thank you.

    I’ll have to hope a Mac user will chime in. On my Windows 7 and 8 machines with standalone, Cubase 9.5 and Reaper, I’m not experiencing and graphic issues.
