Please explain FPS

[OHN 1]

Come on please, theres nothing wrong with the fps counter. download fraps and check it out your self if you have nothing better to do.You dont really believe that the team would implement a fps counter that shows too low fps :D.

[GHarrall 494]

Maybe you have poor eyesight? :-lolI cannot tolerate it at all below 15-18FPS.18 FPS is my bare minimum. 20-24 seems ok in FSX if you can get it.I currently get 30FPS locked in FS9 fully loaded with addons.

Don't know about him Robert, but you should believe it for me. Sliders mostly right, Autogen dense. 22-25 normally, 12-18 big cities depending on wx and AI. The trick is yes being a good twkr but also using the right components in your build, and knowing the finer points of tuning them.

So Rhett, would you be so kind to share the tweaking you have done to get those great FPS so that we all can benefit from it.Thank you so much.

I know what the OP is saying, but I wonder if it has to do with what sorts of planes you fly. If my FPS drops below 10 there is a *little* stutter, but it's still playable. I fly small planes and I imagine since the view is updating in very small increments the jerkiness of low FPS isn't as apparent. Who knows, but I can definitely say if I was running 10FPS with any other game it would be unplayable, not so with FSX. In any event, I've been able to get more than satisfying performance both on my old system and my newly upgraded one. In fact with the new components I can max out just about everything but traffic volumes (keep it at 30%) and still get a very enjoyable experience.Old System:Althon X64 4200+2GB DDR 400 ram7800 GT OCNew System:E6600 Core Duo2GB DDR 800 ram8800GTS(yeah it's sweet and the intel chip blows my old athlon out of the water.)

Ha ha!I hear the squeak of the hinges on Pandora's box...Ever since we have been able to set a max frame rate (and I can't remember when this feature appeared) I have set my max frame rate to 15.Wikipedia has this on Persistance of Vision:"Through experience in the early days of film innovation, it was determined that a frame rate of less than 16 frames per second caused the mind to see flashing images. Audiences still interpret motion at rates as low as ten frames per second or slower (as in a flipbook), but the flicker caused by the shutter of a film projector is distracting below the 16-frame threshold.Modern theatrical film runs at 24 frames a second. This is the case for both physical film and digital film systems."I figure that 15 gives the sim some "headroom" to load scenery, effects etc.However, there is something else going on, a steady 15fps or even 10fps I find quite acceptable (because I can't afford a faster system right now!) its the 3-4 fps that kill the sim.Also it always happens just when you really don't need it - trying to heave the 747 sideways because you messed up the approach.I always console myself that if I can land at sub 10fps in the 747 I will probably do really well once I get the "dream machine"Geoff

Er,I just read the rest of the posts.Promise - I DIDN'T look at the MS page on framerates before posting...Geoff

Do a little more reaearch. Or, failing that, just believe what you will. I have neither the time nor the inclination to go through this issue again...and again...and again...Doug

>My ATIS runs totally smooth on top even when I show 8 FPS.Well, this depends again on what you call "smooth". At 8 FPS, i'm 100% it's not smooth at all but jerky. ATIS will not run smooth under 20, is barely acceptable between 20 and 24 FPS, gets better between 24 and 30 FPS and is smooth over 30 FPS.At 8 FPS, nothing is "smooth" because your eyes/brain will notice the time between each changing image. That effect will only dissapear at FPS rates over 24.

Actually there's nothing wrong with fps at 13 for example. I get those with FSX in populated areas as well as with the QOTS with heavy scenery, clouds, sliders to the right, etc in FS9. Both sims behave pretty much the same with those fps. My PC is totally tweaked and 12fps is no stutter at all in any of the two programs.The problem is that FS9 is able to run awesome addons such as the PMDG products, together with cloud9 sceneries, clouds maxed, etc, etc, and at the end with similar performance I get a way more enjoyable FS with FS9 than with FSX. I have lots of photoreal sceneries, which look better than FSX default, or in other areas I have GE Pro that equals at least the ground in FSX. My FS is 99% addons, mostly payware. Even my sky color, clouds, water, etc is addon. Not to mention aircrafts, airports or scenery in general. The big complaint is that if you ever dream about using FSX with most of what makes FS(9 in this case) a great FS, which is addons, your 13 fps will drop to probably nothing higher than 7/8 fps, and that will make you stutter no matter how good the program is and how well your PC is tweaked.Leo

I sometimes wonder if this FPS reading becomes the subject of peoples vanity! If you are acheiving 10-15FPS and consider the sim smooth and to your liking then fine. If you prefer 25-30 then fine too. People saying "my FPS reading is bigger than yours" gets a little petty at times. Rarely are two PC's alike and rarely are two peoples opinions alike, consequently there are so many variables we could go round and round all year on this subject. At the end of the day you are either happy with FSX or not. The original poster is clearly happy with his siming experience so MS has acheived what it set out to do. I personally was not happy with my 20FPS average and have reverted to FS9. I am a bit miffed at losing

[ryanbatc 12,847]

In everything I've done and seen, I notice the largest stutters come from a high variance in FPS. If you have the min/max/avg display enabled it will tell you when you go from 10FPS to 26 to 31 back to 21. When your PC is jumping like that (set your slider to unlimited) you tend to get more stutters. If you lock at a fixed value normally the stutters go away.Try it

[Guest bjablonka]

Thank you Leo. I am also flying mainly add-ons and have tons of scenery improvements, maybe that is the reason that we get smooth video with lower FSP.
