disable raw input mouse with nividia reflex

[mbm]

I have tried to disable raw input in games where this option is available etc. battlefield.
the responsiveness seems MUCH better with it OFF.
is it because of reflex as the render starts with the mouse

Nvidia Reflex is designed to dynamically cap CPU drawn frames to the GPU so the GPU usage remains on or below 97%.
Without Reflex and the GPU usage is @ 100% the CPU drawn frames get put into the render queue because the GPU cannot keep up which causes delay/latency.

Raw input is usually the most cosistent, unless your DPI is just to low.

What motherboard and CPU do you have?

This is caused by a bug with HAGS and Reflex and yes it appears to cause input lag. If you disable HAGS you shouldn't see 100% usage anymore.

^Yep

I have that same CPU but a different mobo, so try these:

Open device manager, find High precision event timer and disable it.

Open command prompt (admin) and input the following commands:

Code: Select all

bcdedit /set tscsyncpolicy enhanced

Code: Select all

bcdedit /set disabledynamictick Yes

open registry editor and navigate here:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\PriorityControl
Find Win32PrioritySeparation and modify the hex value to 29

Restart the system to apply the changes and it should feel more responsive.
These tweaks give priority to programs that are in focus like games and changes how the system timers are handles which further improves latency and consistency.
