Lack of performance (crackles) when I use NI Izotope Elements under my DAW Reaper

Xavioch

Hi,

I'm having problems with iZotope Elements (Ozone + RX).

I have a laptop running Windows 11, intel i7 processor, 16GB Ram, 512GB SSD.

I use Reaper as my DAW and my midi interface is a Komplete Audio 6 with ASIO driver.

As soon as I add more than 1 FX Izotope to a vocal track, Reaper starts to slow down in jerks with noises and crackles. I use NI virtual instruments as well with Kontakt 7 (Glaze or others instruments).

With Reaper, my buffer size = 512 and 44.1 Khz.

On the Reaper forum, other users of Izotope effects complain of the same slowness. Reaper recommends writing to NI to address this issue.

What are NI's recommendations for configuring a PC to run well under Reaper with Kontakt 7 and Izotope (what type of processor and what minimum frequency, as well as RAM or graphics card configuration)?

Regards
