"Target FPS" - what does it do?

[[DBS]TH0R]

Can anyone tell me what does the setting "Target FPS" under Graphics settings do?

 

 

What I can tell is that it is limiting FPS based on the value set. Is it only the limiter or...

 

Does it also do some optimizations to achieve the targeted FPS more easily? And most importantly, does it induce any additional input lag?

 

Thanks

I think it has something to do with the dynamic resolution.

Hover the mouse over the Settings.

So if you get below the target FPS, the game will reduce the resolution by the factor set in the dynamic resolution slider.

It basically just makes the picture blurry but doesn´t help in any notable way.

I don’t think you ever really want to use this settings. It just makes the game a blurry mess. Better to tune your overall settings to give you a good experience most of the time.

It is a convenient way to limit the frame rate to the chosen value. One could want to do this for several reasons, such as reducing the load on your system or making stutters less noticeable by forcing a lower but more stable frame rate.

It has no effect on optimization unless "Dynamic resolution factor" is not set to "Full".

Although I have not tested this, I believe that there will be no additional input lag unless you choose a value that is below your monitor's refresh rate.

Thanks, seen that. But that doesn't really explain much or how it works. The tool tip explanation was the basis of my questions here.

I've tried that, and the blurry image looks horrid.

 

So, if I keep it at 100% and set an FPS limit - it will then just function as the FPS limiter?

it might be as simple.

 

I have to check that but I guess this is what happen on my side, as I can see my FPS counter stuck to 50 most of the time and I did'nt notice any blurryness...

If I understand it correctly, an FPS limiter keeps your graphics card from working too hard. If your GPU is too loaded it can actually increase your input lag.

FPS limiter is a bit different than VSync. I assume that's what Target FPS is.

[Alonzo]

Target FPS is the number of frames per second the game tries to run at. If you're at less than this, it will reduce the resolution using the resolution scaling factor, until you hit the Target FPS. If dynamic resolution factor is 1.0, the setting does nothing. If dynamic resolution is less than 1.0, this setting will make the game look like garbage. I would advise against using it.

[[DBS]TH0R]

Yeah, setting dynamic resolution to anything lower than 1.0 looks horrid. But what about just using FPS limiter? Does it increase input lag or simply caps the FPS?

 

This video led me to posting here:

 

 

 

Because I am currently running no V-Sync, either in-game or in NV CP - in order to get the lowest input lag. Using V-Sync in combination with NULL will give the smoothest visuals when on G-Sync monitor. I can confirm that (conclusion in the video).

This is interesting

 

 

[[DBS]TH0R]

Indeed it is. That is why I am not using Target FPS option until I can back it up with some data. I did turn off V-Sync and am using NULL for the time being.

[LLv34_Flanker]

S!

 

I do not use that feature either. VSync off and Target FPS off, rest controlled by NVCPL. No tearing or stutter even FPS goes above 200. Screen is a 200Hz one.

Input lag on a flight sim where you're using (presumably) a joystick? Seems like an odd thing to worry about. I can see that for twitch games like an FPS, but a flight sim?

Could input lag be perceivable in head tracking or VR? Otherwise yeah I don’t see it as a real issue. The topic is interesting though.

All valid points there. Precisely because no one has bothered to compare a flight sim in this regard.

 

The inception for this idea came when I switched from a run of the mill 24" 16:10 (1200 vertical) Dell screen, to the current 2560x1440 144Hz G-Sync screen with esports grade low input lag. I started to notice more head on shots landing and overall more snappy game play, like this one:

 

 

Better snapiness is also noticeable on Track IR movements. Though, it took me a while before I fine tuned the in-game settings to my liking.

If in VR be sure to increase the target frame rate in monitor mode (also it should not influence VR by default). Before I increased it to 144hz the VR frame rate was locked to 60 FPS when the HUD is turned on. (Probably a bug).

Hi Folks,

 

I realize this topic hasn't been posted to in a while but I thought I would post my questions here. I have been posting a lot lately as I start to get more immersed in this awesome sim.

 

My questions: Is it okay to set my Target FPS at 120 if my monitor refresh rate is only 75 Hz? And does setting a Target FPS cause any loss of enjoyment or fidelity in the game? If setting at 120 doesn't have any adverse effect on graphics quality or fidelity, then I might keep it at that setting to relax the stress on my graphics card.

 

Background: I have a 6 year old 19 inch LCD monitor which is still in great shape. According to specs it has a 5ms response time and a vertical refresh rate of 75 Hz. I also thought the spec sheet said it had a horizontal refresh rate of 60 Hz I think.

 

I have my system specs and graphics settings at the bottom of this post. I noticed something interesting while playing around with the Target FPS. When I turn the Target FPS to "Off" I was averaging like 250 FPS - in some cases over 300 FPS in single player and some scripted campaigns. It actually was amazing to see such high numbers. Anyway, after playing like 30-45 minutes with those FPS numbers my machine got quite hot and the fans really started to get loud.

 

Out of curiosity I exited the game, waited a while, and then restarted the game and set my Target FPS to 120. After another 30 - 45 minutes my system was pretty whisper quiet and didn't feel hot. My FPS was constantly at 120 and never moved from that although I didn't fly exactly the same missions.

 

So that got to me thinking that maybe if I can have 120 FPS all or most of the time, then maybe having FPS numbers over 250 most of the time was taxing on my video card? - but then I had to ask myself was I losing something in so far as texture quality, draw distance, fidelity, graphics etc... by setting a cap of 120 FPS?

 

Just curious to see if anyone has any thoughts?

Just spotted your reply @jg123410 by accident and seeing how no one replied - if your system is running hot, I'd keep the target FPS on then.

Thanks [DBS]THOR - sorry for the late response. I appreciate you getting back to me.
