Try using 1 or 2 band dynamics, for example, instead of all 4 bands.

Using fewer crossover bands can save significant CPU.

Right-click on any meter to bring up the options screen for that meter.

You can disable meters in their option screens.

As buffers become very small (latencies are very low), the Digital EQ and Digital Crossover will consume more CPU. When buffers are too high (latencies are too large), meters will update very slowly and performance may suffer.

Try changing the buffer size and/or latency setting in your host application.

Every now and then you may find a cpu hog like uhe diva for example that will give abnormal spikes with certain. I never reach a point where there's crackling and slugish perfomance though. I have a i7-4770k with 12 GB of ram and Ozone still taxes a small bit of of the cpu usage.

If you're not using modules for processing, you should be sure to bypass them to conserve CPU power. Maybe a i5 cpu with 8 gb of ram to have a substantial upgrade.

If you do start to reach the limits of your particular machine, here are some tips for optimizing your CPU: While continuing to push the limits of high quality audio signal processing, Ozone offers significant improvements concerning CPU optimization allowing your sessions to run more efficiently.

The combination of multiple DSP modules performing analog modeling and a half dozen real time meters dictates that it requires more CPU processing than a typical plug-in. Ozone performs a significant number of calculations when running.

Unlike many single task plug-ins, Ozone harnesses the power of six plug-ins in one.
