Mouse movement issues in the 2006 SDK version User reports twitching or erratic mouse behavior in the source code.
Back in mid-2017 I was using a HL2 mod named The Hidden: Source. I had played that game since 2014 without any issues. One day my computer started bluescreening and would freeze or display a DPC_WATCHDOG_VIOLATION error. So I upgraded to a new PC in late 2017. After installing my Steam library and transferring the mod files from a USB stick, everything functioned normally until early 2018. Then I encountered problems in-game—my mouse would randomly "twitch" when moved. I attempted to reinstall the game and reset Windows, but it remained unstable. Others noticed similar issues; an old Windows 7 laptop played fine, but switching to Windows 10 caused the problems. If you need clarification, just know English isn’t my native language.
Currently, the hidden feature seems quite outdated, though it shouldn't be entirely unusable. If you're unsure, try turning direct input on or off to see what works best.
I've checked all the mouse settings available. So far, nothing has resolved the issue. (I should note I can play the game with a PS3 controller, but using a joystick makes it hard to move props.)
