Cubase pro 10 clips and stutters CU95 perfect same project

So recently paid fpr the upgrade to cu10pro, and i used it, set up templates, and on the same 10-32 track sessions in CU10 it constantly hiccups, stutters, and is UNUSEABLE in a professional environment. Loading the exact same session in 9.5 runs perfectly. Im using Macbook Pro High Sierra 10.13.6 (17G3025) MacBook Pro (Retina, 15-inch, Mid 2015) 2.8 GHz Intel Core i7 16 GB 1600 MHz DDR3 AMD Radeon R9 M370X 2048 MB
Intel Iris Pro 1536 MB using UAD thunderbolt Apollo 16, Apollo 8p, and 2 octo satellites, along with Softube Console 1 . Its a mess and I just wanted to let you all know I cant use CU10 and will now forget its been updated and stick with 9.5 Thanks
