Which game settings cause the most lag? - Nvidia Reflex Latency Analyzer
Check out Storyblocks Video at www.videoblocks.com/LinusTechTips
Nvidia’s G-SYNC module hasn’t had a lot of love lately, but that all changes with new Reflex-enabled displays like the ASUS ROG SWIFT PG259QNR, which can tell you just how slow your game really is.

    Whats dumb about windows is that you have to go into indexing options and check mark to tell windows to look into your hard drive and others to do the search thing.

    on plus boost just turns it on plus keeps the gpu in performance mode its the same as setting prefer high performance in the nvidia control panel

  • bloemundude

    Linus, you're making assumptions in this test. Some games may use a virtual bullet along with the physics engine to simulate bullet drop and recoil. Along with this could be a more realistic bullet starting point at the back of the barrel, not showing a fiery blast until the bullet accelerates to the end of the barrel. You would need to know for a fact how each game simulates shots, though. Just my $0.02.

    you cant just lower refresh rate and expect less input lag, you have to cap the framerate below monitor refresh rate at something that lowers gpu usage below 100%, this reduces the frame buffer between gpu and cpu and gives you better input lag. Which is basically what the reflex software in game does, but without lowering gpu below 100%. On + boost changes your power settings for your gpu to prefer performance so the card will clock as high as it can

I have been using a 32-bit Windows Vista Desktop since the beginning of this pandemic... I would be really thankful if you give me a decent laptop from your huge collection of gadgets, it would make my life a lot better. I am really serious about this...please reply to this comment if you want to help (everyone please like this comment so that it comes to his notice).

    Wasn't that a perfect opportunity to test WIRELESS MOUSE LATENCY? Age old Question.

  • vivhidd

    Are you sure the monitor catches up the whole input latency from the "click of the mouse up to the muzzle flash appearing"? I don't know how that would be possible, since the monitor has no absolute information of when the key was initially pressed. I mean, no matter what the monitor does, there has to be an input latency between it and the mouse (or whatever), before it even shows you the so-called "precise" input lag. The monitors "input-scan" is not delay-less.

    3:43 wrong Antony, it's (21ms) better than a frame @ 30fps (33ms), but not better than @ 60 (17ms) or was Linus saying it wrong? Because later at 1080p Linus says it's 16ms...

    Any reason why you didn't test refresh rates that the average user uses? Like 60hz or maybe 144hz? Great video for the 5 people who have a 240hz display and think about upgrading to 360hz.

    How many times do I need to say that ‘Ultra’ low latency mode INCREASES latency if you are not GPU bound (99% GPU usage) use the ‘On’ settings for best input in CS/VAL/etc.

  • hi

    the on plus boost does something were it keeps the gpu clocks high and it somehow keeps latency low.
