Important Note

This article addresses input issues exclusively. Please see the Troubleshooting Gameplay and Performance article if you are encountering poor game performance (for example, choppy video display and occasional stalling).

Common symptoms of mouse and keyboard lag include delayed response time on movement and firing controls (for example, one's player keeps moving or firing for several moments after one has released the key or mouse button to move or fire).

HL Mouse Filter

*
vgui_emulatemouse

This is an HL option that forces a software mouse cursor emulation (this may be useful for older graphics cards which display a flickering mouse cursor). Enter vgui_emulatemouse 1 in the console to enable this feature.

PS/2 Peripherals

*
Revert to the Default Mouse Drivers

Uninstall any specialty mouse drivers and allow Windows to detect and install the default mouse drivers.

USB Peripherals

*
Interference from Other Peripherals

If you have other USB peripherals plugged in (for example, a digital camera, USB disk drive, or USB sound or video capture device), please try unplugging the non-essential USB devices when playing.

Avoid using USB hubs to connect your mouse and keyboard - plug directly into the back of the computer to ensure the best performance.
*
USB Power Saving Mode

Please see the Troubleshooting Mouse Problems topic for instructions to disable power saving for your USB devices.
*
Test USB performance against PS/2 performance

If you continue to encounter issues with USB mouse performance, please try using an adapter (many USB mice come with a PS2 adapter) to plug into the PS/2 port. (You may also try using a generic two-button PS/2 mouse to help determine if the issue is specific to USB input.)

Wireless Peripherals

*
Replace Batteries

Please ensure you have fresh batteries installed in any wireless peripherals as a preliminary troubleshooting step.
*
Update Drivers

Ensure that you have the latest drivers from your wireless peripheral manufacturer.
*
Test Wireless performance against PS/2 performance

Try using a generic two-button PS/2 mouse to help determine if the issue is specific to wireless input.

if you try this and nothing works....then what i've found that works is if you start dod, then press ctrl+alt+del and set the priority for hl.exe to the lowest, it will fix it....it seems to be a random bug, thousands of people have gottent his problem and only affects one game.....i think steam are being gits

Mr. Black

What is the problem? High Cpu usage and Mouse movement lags?

Yes both rainer

Yes both rainer.

do you have a nvidia or ati based graphic card?
did you update the graphic card driver?
did you check your event log for error messages or warnings?

the high cpu usage and the mouse lags are only when you run dod or is this also happen when you do normal things with your pc?

Ati Radeon 9550. Newest driver. I check log, no errors.
The CPU usage is all the time, but only sometimes. With the hints of shane my pc works now better BUT the pc crashed sometimes without a reason. And the lags comes stimes too

what means "the cpu usage is all the time, but only sometimes" ???
maybe we better switch the languages to German ...

Manchmal springt die Auslastung hoch und geht dann wieder runter und SELTENST ist sie immer hoch und PC stürzt ab. Sehr gay

Ich frage morgen mal einen Kollegen, der hatte das gleiche Problem.
Lag glaube ich am Treiber der Grafikkarte.
Werde ihn mal fragen, was er gemacht hat.
