Why only 85fps

[markjonesx]

I have never ever figured this one out!

Playing Counterstrike as a bench mark, I've got the fps set to 99, however my monitor will not refresh any more than 85Hz and hence 85 fps.

Can I get the refresh rate up of my monitor? if so how?

Monitor is IIyama Vision Master 1451

Go in display settings and disable or turn off Vertical Sync....I believe that'll solve your problem.

 

[markjonesx]

Well, I didn't know that, you learn something new everyday.

But anyhow, it doesn't make sense to have your graphics card render more frames than your display device will show. Hence, the capping at the monitor's refresh rate does make sense alright. In real life. In mine's-longer-than-yours land of benchmarking it doesn't.

 

[Wurrmm]

Even if it shows you getting like 150 FPS you are really only seeing 85 if the refresh is 85, so capping with vsync can allow you to turn up tweaks like AA and AS.

 

[kylebisme]

yes and the 85 that you do get are made out of various frames so when you move you get disjointed images. but it is handy to turn it off for compareing videocards in benchmarking.

Actually, there was an FPS testy thing that showed 2 images side by side running at different speeds, and with monitor at 85Hz, one thing at 85 and the other at 150, the 150 looked smoother, you could tell a difference, so you can see above 85fps.

thanks for diplaying your lack of comptuer knowledge. it's a great way to be castrated here on the forums.

if your monitor is set to 85Hz, it updates the screen 85 times in one second. this being said, if it only updates 85 times per second, any additional frames would be "wasted" since you monitor is not actually displaying them

 

[kylebisme]

besides in general people don't notice any difference much above 30fps, some peoples eyes are more sensitive to it than others but for instance anything over 40fps is wasted on me. granted in a timedemo i would likely want more as there will be low spots much lower than the average but as long as it stays above 40 i can't tell you if it is faster or slower without a framecounter.

:frown: I would say anyone who becomes adjusted to more than 30fps will notice it very quickly. I am playing splinter cell at the moment and at an average of 38fps its not smooth at all.

 

[kylebisme]

oh sure but i am speaking of people as a whole here, the majority of which do not generally play much videogames or do so on lesser or illconfigured hardware. take one of them and show them a game running at a rock solid 60fps and then cap it at 30fps and they will not see a difference. like i said, anything down to 40fps is fine for me and only when it gets below that can i notice at all; i am sure some people are more sensitive than that but again the norm is still fairly low.

Your game should not "look" smoother at higher FPS anyway. Framerate is not so much presentation related in the quality of the picture.


I laughed though when I saw the topic: "why only 85 fps?" . lol. FrEaks. I hope you do not have a heart attack playing Doom 3 or Half life 2 at 10 FPS. I can see you wanting very high framerates in online play, but crap, 40-60 avg. fps is plenty for that. Over 85 FPS? You soo crazy.

 

[Peter D]

my god, only 85? cuz you know the eye cant see past like 30 or 40! hahah

another note, personally i wouldnt use a game that can get 100fps on a gf2 for a benchmark.. lol

I can usually tell when something dips below 50-60fps, and I don't like it that slow. I've been spoiled with a GF4 Ti4200, and now a Radeon 9700 - now 40fps looks bad to me.:Q Of course, I'm also one of those people who can see flicker if the refresh rate is below 85Hz; I run my desktop at 120Hz. The monitor supports 144Hz max, but only the 40.xx Detonator drivers would see it back when I had a Geforce4. My Radeon 9700 Pro doesn't seem to see that refresh rate.

 

[RyanVM]

The main problem one gets with Vsync on is that framerates have to be in multiples of the refresh rate. We'll use 85hz as an example. Say your monitor can't display at 85fps. What then? It goes down to the next whole multiple, in other words, 42.5fps - two frames refreshing on the monitor for every frame in the game. If it can't keep up with that, down to 21fps. That's where choppiness can happen as I understand it - when your computer is forced to seriously drop framerate in order to sync up with monitor refreshes.

If anybody knows about this better than I do, feel free to correct me, but I'm pretty sure this is how things work.

So any chance you can translate that ? A ahigher fps will give a smoother look to a game when panning and in general movement. I find the a constant between 60 and 80 is OK much lower and high speed radial movements look jerky

I used my eyes and saw a difference, only a small one, but a difference.
Maybe my eyes lied?

really? care to explain how it is possible to see a frame when it's not displayed?

acually that is just the way it works when you force v-sync with the ati's drivers and not quite then; after 42.5 you get 28.333fps which is 85/3. but if the game has a vsnyc option and you do not force it in the drivers it will not do that. ether way it does not really bother me though as 42.5 is really about where i want it anyway and if it drops to 28.333fps for anything more than a moment then i want to turn my settings down anyway.

Yes!

Don't trust your eyes, I suggest you poke them out before it is too late.:evil:

Since you're off castrating the guy when he's being perfectly polite maybe you should go do some reading first. Enabling Vsync can actually cause you to render at MUCH lower framerates than your refreshrate. Setting it to vsync on an 85hz monitor CAPS it at 85hz but in many cases causes the video card to wait a couple frames for the next refresh to start. The reason he was able to see a difference isn't because he saw one rendering at 85 and one at 150 but rather one was well BELOW 85 and the other was at a fixed 85. There are other reasons to leave vsync off as well...some games tie the physics engine to the rendering engine. The famous "megahealth jump" on DM13 in Quake III is a perfect example.

Those of you that think the human eye can only follow up to 30 frames per second are badly confused. I can easily *see* the difference between 80 and 100fps. My gameplay is typically not affected once a minimum 60fps is reached though...guess the eyes are still quicker than the hands I suppose.

One last thing: your screen may look smoother when you are sitting still at higher framerates, but if your mouse is only sampling 20 times a second things are going to look bad when you try to whip a 180. Don't forget to use PS2rate or a USB mouse

I'm fairly certain you are correct.

try com_maxfps 40 and note that you can get the megaheath just fine.


and your agument about vsync lowering the fps is only right sometimes and still has nothing to do with the argument of two monitors at 85hz but with one running at 85fps and the other at 150fps.

like i said he is wrong, try looking into what i said if you want to be certain of something that is true.

FYI framerate caps are usually controlled by vsync and other settings such as com_max FPS. Also note that game caps are usually at least slightly different to vsync due to the way things work.

But anyhow, it doesn't make sense to have your graphics card render more frames than your display device will show.

Even if it shows you getting like 150 FPS you are really only seeing 85 if the refresh is 85,

if your monitor is set to 85Hz, it updates the screen 85 times in one second. this being said, if it only updates 85 times per second, any additional frames would be "wasted" since you monitor is not actually displaying them

False. A monitor is quite capable of displaying partial frames and these transfer into better mouse smoothness and sensitivity (among other things). Two frames joined into one refresh cycle display more information than just one frame displayed in one refresh cycle.

so capping with vsync can allow you to turn up tweaks like AA and AS.

You can do that anyway as vsync has nothing to do with any of these settings. In fact enabling vsync can slow you down even more when you use these settings as it often cuts your framerate to half of your current refresh rate, even for extended periods of time.

besides in general people don't notice any difference much above 30fps,

The only people would be non-gamers and/or people that have never seen anything better than 30 FPS.

above 40 i can't tell you if it is faster or slower without a framecounter.

Its more like 60 FPS for me with regards to straight animations but for things like mouse sensitivity and movement I can easily spot the difference between 120 FPS and 75 FPS.
