I recently upgraded to v14 and used it this last Tuesday for our live show. During the show I noticed the CPU usage was running 80-100% while it had run between 40-50% under v13 using the same preset. After the show, I checked all my settings and everything looked fine. After some additional testing, I found the problem was the Process - "NT Kernel & System" was running between 20-40%. So I re-installed v13 and NT Kernel process is still using way too much CPU.

So I started with a clean preset, added two webcams (C920's) and with noting else running, no recording, no streaming and the NT Kernel process is running at 11-15%. Delete the two shots and it's back to 0%

System Specs:

Windows 7 Ultimate 64bit
Core i7 3770k overclocked to 4.2Ghz
32GB or ram
SSD - OS Drive
SSD - Recording Drive
Other SSD's and HDD's
AMD Radeon 7850
2 PCIe USB cards, one for each webcam

The only difference between the last time we used v13 to now using v14 was the installation of v14. No new hardware, no Windows updates not even the moving of a USB device to a different USB port.


Any ideas?
