Win-10 High-CPU

Get rid of lag and high CPU usage with in windows 10, while using a dock. I have seen Windows Driver foundation get as high as 62% when moving items on my screen.

        I have a DL-165 device on a 2011-era AMD Bobcat-based X120e netbook. It works *if* I increase priority of the WinUDFHost.exe process to High or Realtime via Task Manager. If I don't, it lags.

        It's possible that you're already doing this at a thread level; examining the process using Process Explorer suggests that the busiest thread is two priority levels higher than the others. However my experience suggests this is insufficient to ensure adequate performance under competing loads. It may be that increasing the priority of a single thread is not enough, if several are involved in processing.

        Increasing process priority automatically could improve perceived performance of these older devices (which are still being sold new), especially on the older systems for which lower-resolution screens are most suitable, and which may only have access to USB 2.0.

        This is a relatively old CPU but, it has CPU instructions up to SSSE3. Essentially all systems currently in use have SSE2 and SSE3, which were introduced several years before this hardware. Targeted use of intrinsics or recompilation might reduce CPU usage.

        If I compile anything in visual studio (not using parallel compilation) the CPU doesnt exceed 30% usage, but the display link connected monitor lags the mouse by 0.3 seconds. Its like playing HalfLife on a 33.6k modem, getting 3-5 frames per second.

        There is no reason for this when there is plenty of CPU available.
