Persistent FPS Drop Triggered by Keyboard + Mouse Macro in Games

Hi,

I’m experiencing a persistent FPS drop issue on my Windows 11 PC (Version 24H2, KB5063878) that occurs after using a keyboard + mouse macro in games like Roblox and Valorant.

Here’s the situation:

My keyboard has a macro that spams I and O while holding Q.

I also guide the macro with my mouse: I double-click the right mouse button, then hold it on the third click while moving the mouse to control the macro.

The macro works normally for a consistent amount of time — this is how I’ve used it for the past 3 years without issues.

After the macro has been running for a short period, any mouse movement causes FPS to drop significantly, while other inputs remain fine:

Walking around using W, A, S, and D works without any FPS loss.

As soon as I move the mouse, my FPS can drop from 160 to 90, and it stays low as long as the mouse is moving consistently (even just spinning in a circle).

The issue does not cause high CPU usage (CPU barely moves) and only consumes around 15 MB of memory.

This occurs with different macro software: both TGM macro and Logitech G HUB trigger the same behavior, though Logitech takes slightly longer to start.

I have tested the macro outside the game using online keyboard testers — everything registers perfectly.

I have also tested this issue in Valorant, which shows the problem is not specific to Roblox and points to a system-side issue on my PC.

When I rejoin the game, everything returns to normal unless I run the macro again.

I have run multiple malware and virus scans, and all came back clean, so it is not caused by malware.

Steps I’ve already tried to fix this:

Reinstalled the game and macro software completely, using Revo Uninstaller to remove all traces.

Updated and reinstalled all keyboard and USB drivers via Device Manager.

Tested multiple mice — issue occurs with all of them.

Verified that the FPS and inputs are fine before the macro runs.

The game itself works perfectly until I use the macro for a short period, and this issue only started happening after the most recent Windows update (KB5063878). However, nothing about this update seems directly related to keyboard/mouse input, which is what makes this particularly confusing.

I would like guidance on how to fix this persistent macro-related FPS drop.

Thank you for your help.

    Hi!

    Thank you for the information. What I recommend testing is to Roll back KB5063878 since this is the closest experience that you noticed the issue started. The latest update contains “spam filtering” for HID devices. (update detects unrealistic human input.)

    a. Go to Settings → Windows Update → Update history → Uninstall updates

    b. Look for KB5063878 and remove it.(check date as well and compare when the issue began)

    c. Reboot your computer and test the macro again.
