im using a tapco link usb interface, im using WDM Kernel Streaming audio system because that was the default it assigned to reaper by my interface, I switched to Asio4all and i didnt make any difference, I am running 33 tracks, slate drums with 16 outputs and some dead tracks that arnt being used, 4 tracks of tse x50 guitars, and 4 tracks of tse x50 for a different section, one bass track that has a ton of proccesing because its pitched guitar and 2 vocal tracks. And its CPu overload thats causing with problem.
