I thought they had already fixed it? :/ I take it the patch wasn't particularly effective?

Depends on the root cause of your DPC latency, but this can help in some cases:

Open Elevated Command Prompt

Run: "bcdedit /set disabledynamictick yes"

Reboot

What are you using to measure the latency because looking at the first site in Google results I see this

--

Windows 8 Compatibility: The DPC latency utility runs on Windows 8 but does not show correct values. The output suggests that the Windows 8 kernel performs badly and introduces a constant latency of one millisecond which is not the case in practice. DPCs in the Windows 8 kernel behave identical to Windows 7. The utility produces incorrect results because the implementation of kernel timers has changed in Windows 8 which causes a side effect with the measuring algorithm used by the utility. Thesycon is working on a new version of the DPC latency utility and will make it available on this site as soon as it is finished.
