But again drivers/hardware can override this setting, so it hasn't necessarily have to work. Because i am unsure if i have to put there either this or that. Or i tried put there IrqPolicyAllProcessorsInMachine instead devicepolicy. I am positive i have set it under right device in regedit and i entered under Affinity Policy: "DevicePolicy" and put value 3 in decimal. Interrupts should be spread on all cores, instead being handled only on core 0. It is really strange, that hardware/drivers/windows wouldn't allocate multicore for handling interrupts: my pc isn't that old i have i7 3700k chipset b75m, which isn't best but still. From measuring dpc in latencymon, i have still 400k dpc calls on core 0, while other 7 cores gets 500-7000 for each, which is disappointing.Īnd setting in regedit interrupt affinity doesn't help, because hardware/drivers can override that setting.
I have everything in msi/msi-x mode, except usb.
