Topic: Latency with RME AIO PRO for Portcls.sys and hdsp_64.sys

Hi,
I have the  following system :
7950X
Asus B650e-f
Integrated graphics
2 SSD WD850 and P3 Plus
64gb RAM CL 36 from Kingston running BIOSat defaut setting
running latest version of the rme firmware and driver
No WDM device
All the tweaks (power management, disable superfluous devices)

When I run ableton with the ASIO drivers: i get incredible latency (10 minutes of latencymon yields 3800ms of execution time fr portcls.sys and hdsp_64 around 400ms)

Is there something I can do ?
Kind regards

portcls.sys is not an RME file.
Have you tested the card in another PCIe slot?

Thank you for your message and for your help.
Yes I tried in 2 PCI slots, one directly connected to CPU, the other one to chipset, same execution time.
There is little info on that portcls.sys driver. I dunno how to sort this out...

You don't run latencymon with your daw running but with nothing running.

In that case, there is no problem, portcls is not running, neither is hdsp_64.
