Smooth FPS in FSX, A MYTH?

Recommended Posts

Hello,

I was wondering for all those of you with Ultra high end PCs getting 30 FPS locked with AI Traffic,Addon Sceneries,Dense REX weather and NGX for suppose..

The main reason I am asking is that everytime I get a new pc I get a new Hope that it will run great now and in the end It lags at major airports, Also what not tweak that I have used to make to make it smooth but came to conclusion that it does not matter.

 

So now I am starting to believe that getting smooth FPS(WITH ALL ADDONS) is nothing more but  a myth..As Fsx sits on old technology.

 

I doubt if I upgrade to 4770K or GTX 7 series I will get not much better FPS. I remember few months back when People used to say get i7 2600k series and its smooth as anything but No..

 

 

Low FPS -  Simulation experience ruined for me .

 

So smooth FSX it's really a myth? FSX can never run smooth on any system because it's not optimized for latest technology.? One should think thousand times before spending a lot of money for FSX system.

4.5ghz is the sweet spot i feel for fsx, my fsx is very smooth even in overcast conditions with rex clouds and opus weather. I have droped down to the low 20's in the ngx and it was still smooth.. you would think it was 30fps it was that smooth.

 

I do feel how you tweak your pc and sim is the deciding factor on smoothness but that is only something you can do as not every pc is the same. There is stuff people do that can be wrong for the sim and over tweaking on modern hardware can be a very bad thing and is something to watch out for, the same with to much HD.

 

I use these manual tweaks only

 

Highmemfix 1

BP 0

Affintymask 14

wideviewaspect 1

LOD 5.5 but i will use 6.5 when i fly slow and low

I get 30 FPS mostly everywhere but it does drop to the low 20's at some of the most FPS-intensive OrbX airports. 4.5 GHz 4770K and GTX 670 here.

 

Part of the problem is obviously that FS isn't optimized for new GPUs, making it entirely depended on the CPU. However developers are pushing the 3D engine as far as it will go, which means at this time, they're targeting ~4.5 GHz CPUs during development. A few years ago they were targeting 4 GHz, and before that 3.5 GHz. If you were to make a clean install of FSX and then only use add-ons from 2007 and before, you'd get great FPS with any modern system.

I get it all smooth as long as I stay away from resource hungry addon sceneries and even around them it's usually reasonable 20FPS or so.

 

I think the fact I'm using ATI card might reduce the FPS a bit compared to if I was using Nvidia. Definitely overclocking my I7-2600k from 3.4 to 4.4ghz helped a lot.

it can be realy smooth if you forget about AI traffic, road vehicles and ships and ferries. If yoy fly online, this will not affect you. I have only 15% leisure boats, and everything else to 0% in my traffic tab and i have smooth FSX with all addons. 30fps(locked) 99% of time. Ususaly Fps  drops from time to time only for a second to 27, 28 with no changes in smoothnes. On some airports(which seems to be just FSX bad optimized area)fps can go do 20, and i can see ocasional stutter, but still smooth FSX. This is what you can get with good system and optimization. No chance of smooth FSX with Traffic sliders to the right

A smooth experience, for me, comes down to knowing what areas are the main draws of performance;  in my experience it tends to be heavier weather depictions, AI traffic, and the higher autogen levels.        

 

That's not to say these need to be turned off, just that these are the parameters that I have found will have the greatesing impact on FPS (+/-) accordinhg to whatever scenario I'm in, in FSX.

 

There are of course some settings in FSX that pretty much everyone should avoid, such as FSX's native Bloom

 

But it's the weather, AI Traffic and autogen that I tend to dynamically adjust according to whether I am flying for example, a PMDG airliner versus a frame rate friendly GA aircraft, etc.

 

The exception to the rule of course, being the Majestic Q400, with which I can set high weather (cloud) coverages, a healthy amount of AI, and max Autogen;  and still get a butter smoother, high frame rate count, even in high detail add-on airports.

Well, I have just recently returned to FSX, coming from P3D and X-Plane 10 ( I use to jump between passions, as most of you should know... )

 

I decided that the main aim for me to re-install FSX was to be able to profit from some great add-ons that have been recently released, including the PMDG 777, the A2A C172, and even the Flight1 B200 which I din't buy but look fwd to...

 

Since in X-Plane10 I couldn't use the rather basic and limited ATC, and AI aircraft were a nightmare, and OSM + Autogen scenery is great but together with photoscenery can bring the sim to a stutter state that FSX would envy, I was not using AI or ATC with X-Plane, and was just using the default autogen at lower levels and some photoscenery.

 

In FSX I decided I should do the same, so, no ATC other than the default - which is much better than what we get in X-Plane 10 - and absolutely no AI ( aircraft, cars, boats, etc... all at 0% ). I was also parsimonic with scenery settings.

 

The result is a rather stable between 20 and 30 fps ( using vsync at 1/2 monitor refresh rate through NI ) and being able to do everuthing to that mighty PMDG 777 without noticing any sort of stutters, freezes, etc...

I am flying it mostly smooth on a ~2.7GHz AMD dualcore. Yes.

 

Of course I don't go to mega airports, I don't use AI and supermegaHD clouds.

 

 

Things is, if you keep throwing things at FSX until it is no more smooth, then it will never be smooth.

Achieving a smooth FSX experience is more of a balancing act if anything else. There are some limits, to the engine and to the hardware (when todays hardware works in a quite different way then 7 years back).

DX10 might get you a smoother experience, even with same FPS. You should try checking the guide here on AVSIM in the DX10 section on this forum.

Going to need a 10GHz cpu before FSX is always smooth at any setting and scenery.

 

Turn down settings is all we can do for now.

The answer is YES you can.

 

I'm so greatful that I have found the right settings and tweaks.

Yes, it's a myth, and no it isn't.

 

People have different tolerances. If you're picky it's a myth, but if you are a glass is half full kind of person you can have a relatively smooth experience.

 

Personally I have tried running at 5GHz. It was a tad smoother, but not revolutionary - meaning you can't have it all: Complex airliner + extremely dense cloud coverage + complex weather + complex scenery + extremely dense AI.

 

I live with it simply by using P3D for low and slow flying with very complex scenery, and use FSX stock for airliners and other big and complex aircraft.

Most people respond with "mostly, 99%,usually" because with graphically intensive addons you will see occasional stutters. You have to tune your settings for what YOU consider to be acceptable performance.

 

There is no magic setting that works 100% of the time in FSX.

They have many guides that can assist you when it comes to tweaking.

There are many tweaks out there that can improve FSX performance. Search for bojote's fsx cfg config tool, Word Not Allowed's fsx guide. Depending on your hardware you could achieve smooth flying, forget about the number of frames, or you will never stop looking. Just feel the smoothness you get with different settings. Things that will bring your system to its knees will be the resolution of your display coupled with the amount of anti aliasing you set. Dont expect 30FPS in the NGX with orbx scenery and rex clouds at 2048 or higher. You will not get it. I found that using 1024textures increased the smoothness in my NGX at night with AS2012 textures on a 1440p resolution. Overclock your cpu. Get the cfg tweaks in there and dont use 4x sparse grid supersampling and you should be good to go.

I remember few months back when People used to say get i7 2600k series and its smooth as anything but No.
 
A myth for some but not for all.
 
Funny thing is, I just built a new rig similar to yours, a 2700k, 8GB 2300mhz RAM, 2 10K RPM HD's, and a GTX670 and mine is smooth as silk with FSX usually 25+ at all major hubs with AI, AS2012 weather, the NGX and now also the PMDG 777 and I haven't even gotten to the overclock or defrag portion of my setup and tuning yet.
 
On my old rig which is still in my sig thing and my new rig, I think the whole key is the base setup of the OS, the way you tune Inspector and a few other things here and there. On my new rig I used NickN's comprehensive Win7 setup guide which goes from start to finish setting up the OS and FSX.
 
For me I run minimal tweaks in my FSX.cfg, don't use the 1/2 refresh rate VSync stuff and run the FPS set unlimited when flying the NGX or 777. I also dont use any bufferpool tweaks except for the Rejecthrreshold one. The only time I run locked 30 FPS is when flying simple G/A a/c that aren't too demanding because my FPS is way too high and the fluctuations in FPS cause stutters. When flying the NGX or T7 in demanding airports, unlimited works better for me since I get more FPS with less fluctuations and no stutters. It's almost as if all the scenery, the demanding a/c and AI are like the FPS limiter.
 
Tonight I did my first long haul in the 777 from FSDT KDFW to FlyTampa's OMDB and was always 30 FPS or higher at both airport with quite a bit of AI around me. Smooth as silk the whole way, no pauses or stutters the whole time.
 
I tried the 1/2 VSync refresh rate thing, locking at 30, etc, etc., but when flying a/c such as the NGX or T7 at huge hubs with lots of AI, for me unlimited FPS are the only way to fly. Using the other way for me results in stutters and blurry textures. Plus I dont use any textures that are larger than 1024 on my rig, be it clouds, water, sceneries, etc. Any scenery I buy that has larger than 1024's gets resized back to 1024 and mip mapped. A lot of work, but been running that way for 5 years trouble free with great performance on both my new rig and old one as well.
 
Also, when I run FSX the only two programs running on my rig are FSX and AS2012. I dont have a lot of other stuff going on in the back ground like audio players, web browers, etc. Just the basics of what I need to fly my plane.
 
Good luck in your quest for performance. With the rig you got now and a good overclock and setup you should be able to get great performance, you might just need to try a few different that are out of the norm.

Exactly what I wanted to say. Talking about smoothness and FSX is impossible to do on a forum because everyone has their own view on what is smooth. You can ONLY discuss smoothness when all participants of the discussion are sitting behind the same computer. If you really want to talk about it, you should first define what's smooth but even that is (almost) impossible.

 

Things would have been easier when everyone talked about fps only, but we all know smoothness is about fps (alone). Comparing fps is objective, you can measure it. You can't measure smoothness.

 

Anyway, I am the kind of guy who things smooth fps in FSX is a myth. Whenever I am simply flying and NOT looking at performance (two totally different things ^_^ ) I have to say I generally have smooth performance, but there ALWAYS will be a little stutter here or a hickup there... ALWAYS. So if you really want an answer to the question, I'd say it's a muth.

Eye candy gets better the hardware you need to run requires more cpu speed. Its never ending cycle of incremental improvements on hardware and software. Want smooth flight with shutters down to a minimum and its balacing act. Smoothness matters more than fps.

Actually, you can measure smoothness, but it's a lot more complicated than measuring the FPS. FPS is just the average number of frames the system puts out over 1 second. Smoothness is the "evenness" or pacing of those frames - If you get 20 FPS, it might mean that you get a new frame exactly every 0.05 seconds, but it could also mean that the sim freezes completely for 0.3 seconds, then fires a cascade of frames in rapid succession, then freezes again etc. This is (lack of) smoothness. By capturing every frame, for example by using a high-speed camera, the distribution of new frames over time can be analyzed and graphed.

 

About being picky - I remember when I started simming in the 90's. At the time, 5 FPS was often considered the lower limit, 10 FPS was kind of OK, and 15 FPS was the sweet spot.

+1 on that as to many people fly the fps counters.

 

There is only a few times we should ever use the fps counter, if we are tweaking, testing some new addon or we have a problem and the sim is not running the way it has been.

As a man who fought FSX for 3 months straight when I got it and my new PC, I can tell you with confidence, SMOOTH FPS is very possible, with the right settings, CFG Tweaks and proper Nvidia Inspector settings.   Of course having a new 4.0+ ghz machine is your best friend.  I run at almost 4.8ghz and was still getting choppy, stuttering ugly performance.   I now run with Max sliders, SweetFX, PMG 737NGX, REX, VoxATC with 40% Traffic, FTX Global and several payware airports and get 30 FPS 'MOST' of the time.     Depending on the airport, I can watch my FPS drop down to 20FPS but I learned to stop caring about FPS and started caring about SMOOTHNESS.     Once you learn to stop trying for 150 FPS and start going for 'SMOOTH' displaying of the simulation you will be born again.

Check out JETLINE SYSTEMS.  These are computers built with FSX in mind.  The owner of JETLINE is an aviation enthusiast and an FSX user.  His company builds these systems to the highest standard using the very best components to bring out the best in FSX.

.

I've had mine for over 3 years and I've been a smooth flyer ever since.  No doubt I will continue to be a customer.  I've tried so many systems over the years, but the JETLINE comes ready to go (they actually load FSX on it before sending it to you.) 

 

Just check out their website and decide if this is and option you would consider for yourself.
