Videoprt.sys is giving me high dpc latency. Does anyone know a fix?

Question

Hiya. I am optimizing my windows-partition. Killing all unessecary drivers, services and processes goes a long way. Also due to sloppy coding in XP kernel, I need to set processes to idle priority, to avoid CPU2 stalling CPU1 when maxed. I have also set win32priorityseparation to 25, which is superficially similar to a low-latency linux-config I did.
However still, I have a module "Videoprt.sys" which reports 1.5ms DPC latency. (Using RATTv3) Dpc latency checker also reports DPC latency of 1.5ms. I see computers out there with 10uS DPC latency
Does anyone know a fix for this?
Peace Be With You.

Answer 1

Fixed it needed to have a return null;
this is the code
if
        (MonthjComboBox.getSelectedItem().equals("") ||
         DayjComboBox.getSelectedItem().equals("") ||
         YearjComboBox.getSelectedItem().equals("")){
        return null;
