I have a laptop that exhibits large amounts of input latency in every 3D game I have tried, with one notable exception: Team Fortress 2 can run perfectly at the maximum (high) video quality settings, without compatibility settings or extra launch options. This outsider is throwing me for a loop, as I would expect this kind of issue to appear globally. I have exhausted most of the standard troubleshooting methods I could think of, and am looking for some other step that I may have missed. (Update: I was mistaken, Warframe/Borderlands 2 runs fine.)

Games that run fine: Team Fortress 2, Warframe, Borderlands 2
Games that experience input latency: Bioshock Infinite, Risk of Rain 2, Payday 2, Deus Ex: Human Revolution
Machine specs:

  • Intel i7-7500 (2.70GHz)
  • NVidia GeForce 940MX (1920x1080 screen, 60Hz)
  • 12GB DDR4 RAM
  • 240GB M.2 SSD
  • Win 10 x64

Steps that I have tried, but did not work:

  • Ensure no VJoy devices exist in Device Manager
  • Run games as admin
  • Run in Win7 Compatibility mode
  • Disable fullscreen optimizations
  • Override high DPI scaling in favor of Application, System, and System (Enhanced)
  • Disable Steam Overlay
  • Run in fullscreen/windowed/windowed borderless mode
  • Unplug all USB devices (issue occurs using built-in trackpad)
  • Run games on a second monitor
  • Enable/Disable VSync (from both application and NVidia Control Panel). Enabling VSync in NVidia Control Panel worsens performance significantly.
  • Enable Triple Buffering in NVidia Control Panel
  • Force usage of Integrated Graphics over GPU (worse performance).
  • Updated NVidia GPU drivers
  • Reinstall Chipset Software

Things I have not attempted yet:

  • Roll back NVidia GPU drivers to older version
  • BIOS update
  • Forcing the usage of lower DirectX versions? (Grasping at straws here.)

Any suggestions would be greatly appreciated.

    Does TF2 have raw input enabled?

  • No, it is unchecked (default setting).

  • TF2 is built on the Source engine. Do other Source engine games (Half Life, Left 4 Dead) have any issues? My guess is whatever those other games are doing is taxing your hardware in a way that the Source engine is not, causing a bottleneck. This could be video hardware, RAM, your hard drive read speeds, multithreading, a whole host of things.

  • IDT anyone still owns a cpu that the Source engine can tax; deff not an i7. All of those games are seven different engines. What mouse/laptop/video card? I suspect W10 (the only diff 'tween yours and mine, but I also don't browse the net on it; viruses?) - Payday 2 keeps setting its refresh rate to "23" on me : %appdata\local% "renderer_settings.xml" (use wordpad)

  • Ok, I take it back. I thought all i7s were hyper-threaded quad cores. Yours is half of what mine is; what I consider entry level for a gaming rig, and even mine is almost exactly half of what an Xbox One or PS4 is. - tl;dr: you're trying to game on a laptop with one quarter the specs of a 8th gen console.
