High framerate issue in older pc game

[frozensun]

I'm having issue with high input lag of around 16ms but good fps as you can see from the picture.

Gaming is barely possible.

The pc game is assasins creed brotherhood and I have graphics card more then capable to run this game (R7 370).

Monitor is lg 25um58-p.

How can I resolve this issue and get smooth gameplay?

Try not to cap your fps to 60. My frame time is 7m/s in 144fps, so try not to cap your fps.

Make sure that V-Sync (Vertical Sync) is off and that you are not using any frame rate capping tools.

Frame time is simply the inverse of frame rate, it's not a direct measure of input lag. If input is tied to the frame rate then disabling v-sync can help. In some instances enabling double or triple-buffering can help (but can also have a negative effect depending on the game).

 

60 images per second --> 1/60 = 0,016 seconds per image (~16 ms)

144 images per second --> 1/144 = 0,0069 seconds per image (~7 ms)

How are you measuring this?

 

Do you have a Leo bodnar tester? 

 

Otherwise you should be able to look up the actual input lag for your monitor at 

displaylag.com.

So assuming the OP means that and not input lag,  isn't 16ms perfectly normal?

Hmm. Must be something else then!?

Based on the screenshot, it says frame time is 16 ms, so yeah that's not a measure of input lag and perfectly normal. I think input lag of 16 ms would actually be pretty good and barely noticeable.

Indeed.

Ooh ok but input lag is not the same as frame rate,huh?

As you can see msi a.b. shows 16.7ms.

Is that normal?

Game kinda lags (slow response time) but dont know why.

I turned off vsync but game crashed to desktop.

Let me try the other computer and this monitor.

"high fps" that frametime is normal for 60 FPS

16.7ms IS 60fps. frame time, frame rate, if it crashes without vsync, then try limiting the frame rate to 144 with 3rd party programs.

Oh ok guys thank you.

I thought game kinda lags because high frame time.

Just switched to second pc and the frame time is around same .

Something came to my mind and that is of some monitors response time of just 1ms.

Who needs that if even on higher fps is unreachable?

I mean I dont understand.

Is 5ms of a monitor enough?

... Yeah it was probably some placebo effect tbh, because you thought the framtimes were high... it happens.

 

 

And pro tip : response times have absolutely nothing to do with input lag either. 

 

and yes, 2-5ms is usually fine,  which is "accidentally" the range most modern displays are at. 

 

 

what it influences is ghosting. 

 

a good test is going to a website like this (LTT),  preferably with a white background and scroll through as fast you can so you can still read titles and such,  if that is kinda blurry, that's the response time aka ghosting,  but by all means with 5ms you shouldn't have that effect either.

The response time is the amount of time it takes a pixel to switch from one color to another color (on average). You want that to be as quick as possible or you'll get "ghosting".

 

Like I and others said, frame time is just the inverse of frame rate (1/58 = 0.0172 seconds or 17.2 ms), so once again that is perfectly normal.

 

To measure input lag, you need to measure the time it takes between e.g. a button press and a visual reaction on the screen. You need some hardware equipment to measure it, software can't to do that by itself.

 

Here's a video that gives you the basic idea:
