He says that component changes may have been responsible for the reduced input lag? Did he ever run this test again with the new computer?

I've read on reddit/r/overwatch that you should disable Game Mode, run Overwatch in Windows 7 compatibility mode, and check 'Disable Full Screen optimizations'. Is that legit advice?

I don't see how that would be legit advice. These sound like random settings with no rhyme or reason.

So running in game mode does not lower input lag?

Im playing fullscreen vsync off in cs go.

I don't think game mode has anything to do with input lag. It's supposed to reduce freezes/hitching.

Lag tests by multiple parties have shown Game Mode (at least in exclusive full screen mode) doesn't have lag improvement.

However, it will indeed reduce intermittent interruptions by the system which causes momentary freezes and hitching. (e.g. certain Microsoft Windows system tasks will be suspended/lowered in priority/etc during playing a game).

And you may get lag improvements in windowed mode (borderless maximized window mode).

Reduced lag in windowed mode can occur when it has the DWM-bypassing enabled (getting tearing in full screen borderless window mode). But that is simply a symptom of DWM-bypassing itself -- skipping that extra framebuffer of the Desktop Window Manager (DWM) during windowed mode. DWM does the stuff like composing multiple windows into one desktop before displaying to the screen, translucency effects, etc. And historically, DWM always run in permanent VSYNC ON mode, even in borderless windowed mode. But if you're already in full screen (exclusive mode, not borderless maximized window mode) -- then DWM is already being bypassed even in the days before Game Mode.

I think this is affected only by the "fullscreen optimization" setting, not "game mode."

Yes, thanks for this little clarification.
