N14 Performance Issue Over Time – Nuendo

I’m currently mixing in N14. Buffer set to 512 samples and Asio-guard set to high.

After mixing for a while N14 performance look like this www.dropbox.com/scl/fi/3fqty0spqk6ar833fgaew/N14-512-ASIO-GUARD-HIGH-Screen-Recording-2025-04-27-195713.mp4?rlkey=e3rggpl0p488hyf25lgu8uhfn&dl=0

so I close N14 and open the same project in N13 with the same settings and it looks like this www.dropbox.com/scl/fi/8hfvydxykjv24tbsghg5i/N13-512-ASIO-GUARD-HIGH-Screen-Recording-2025-04-27-200333.mp4?rlkey=4likqgrsm2lmzaqu8cukrtvou&dl=0

I then close N13 and re-open N14 and it now looks like this www.dropbox.com/scl/fi/r5zbyvx9lqyq48o1q7tgq/N14-512-ASIO-GUARD-HIGH-REOPENING-AFTER-N13-OPEN-Screen-Recording-2025-04-27-200711.mp4?rlkey=e2nxucjygvpaxzyvonazg4fga&dl=0

If i were to just quit N14 and re-open in N14 I get no improvement. It’s only by opening in N13 do I get an improvement.

Does anyone else ever have this issue?
