FC2 FPS and stutter

[Squid]

 

You know, whats even more strange I have noticed.....It seems that AA has no effect in this game no matter what I set it to in the NV control panel. I can set it to 2x or 16xQ and it looks the same....still jagged as ever. I'm not sure if maybe this has something to do with it? Not sure, just wish I could figure it out.

Thanks again, still trying away.....

 

 

Have you tried maybe the SuperSampling method in AA?

[theGozr]

First load all your apps that you have when you fly FC2.0 than go to your system manager and check real quick how many services that are running with your windows (?) than look at the load in Memory to see if you have enough Ram left..

[theGozr]

But please also write all the settings i asked ( it is much easier to understand what is going on that way !

 

In many occasions stutters are caused by application on teh background or textures loading

[Wolf Rider]

i have the same kind of micro stutter as asparagin and annoying tearing up / waving like a V-Sync off would cause which gets somehow reduced only by maxFPS=40-50 but not eliminated. I have found also that those two are related. The more the stutter the bigger the tearing up. (vsync from the radeon panel doesnt affect it). I wish ii could get read of this tearing up / screen waving somehow ....

 

I always had that with LO and FC1 and any card, either nvidia or ATI. I suspect that maybe all rigs maybe have it but most people dont pay attention, or realise it. FPS could be high but microstuttering would always be there when looking at the terrain from either cockpit or external plane camera especialy when on low level

 

 

quite often (but not all instances) that kind of micro stutter (looking at the terrain) is from mismatched FPS and LCD screen Hz.

 

Try setting MaxFPS to 60 and doing what you can with ingame settings to get the FPS up to 60

[Squid]

at last, i have just found that v-sync works with FC2 (stoping tearing-up / waving of screen) when i just UNCHECK full screen option in FC2 settings ..... So, reverting graphics.cfg to its original maxFPS=0 and just leave Radeon vsync forced on, tearing-ups / wavings dissapear and i get back the smooth and crisp feel of 50+ fps. Micro stutter still here although slightly improved in some viewing angles. i also noticed that for some reason i think things are smoother with russian birds ...(?)

You can use V-Sync in fullscreen too with D3DOoverider.exe. check link

Jetace could post all your Nvidia settings ? and lets see from there.

 

Are you using Track IR ?

What is your resolution?

Settings in the SIm + Visibily range settins as well ?

 

 

 

 

Here they are :

VGA:

Anicotropic filtering = 8x

Antialiasing mode = override any apl. settings

Antialiasing setting = 8x

Antialiasing Transparency = Multisampling

Extension limit = off

Maximum pre-rendered frames = 4

Multi-GPU performance mode = nvidia recomended

Multi display/ mixed GPU acc = single display performance

Power managment mode = prefer maximum performance

Texture filtering - Anisotropic sample optimisation = ON

Texture filtering - Negative LOD bias = clamp

Texture filtering - Quality = High Quality

Threaded optimization = on

Triple buffering = on

Vertical sync = off

My AA and AF are enabled x8 like i said previously, maybe jagies are from Asus OSD capture program that i used for screenshots .

 

Don't think the screen capture program matter as most just dumps the frame buffer to disk so WYSIWYG. But why aren't you just pressing "Prt Sc" and use the built in screen capture? As said, looking at the pictures you posted they have no/very little anti aliasing enabled.

 

What u mean about nVidia profile to work ? If u have some ideas about tweaking and increasing Vga performance i ll be glad to take ur help.

 

If I understood theGozr post correctly nVidia profiles are not working when using SLI as you do, don't know if this is true or not since I have a GTX 260 myself.

 

To set up a profile under Manage 3D Settings in nVidia Control Panel make sure you point to "simulator.exe" in FC2 "...\bin\x86\stable" directory. Below you find the settings I use, still tweaking but this gives me nice scenery without jaggies and pretty OK performance (still have FPS/stuttering issues when flying low over cities but it could be other things than the GPU).

 

Anisotropic filtering      16x
Antialiasing - Gamma correction    On
Antialiasing - Mode      Override any application setting
Antialiasing - Setting      8x

Edit: Forgott to add that I also load D3D Overrider to enable Tripple buffering in DX.

Why only 1 pre-rendered frame?

Gave me least stuttering down low, simple as that ;)

Try this...

 

-For SLI systems using 4x MS + 2x SLI SS ( SLIx8 ) is good

-Must use Split rendering SFR

-----------

CPU Multicore support = Multicore

Anicotropic filtering = 8x or x4

Antialiasing mode = override any apl. settings ( NOT Enhanced )

Antialiasing setting = 8x or x4

Antialiasing Transparency = OFF

Extension limit = OFF

Conformant texture clamp = Hardware

Maximum pre-rendered frames = 1 or 2 going for "4" will reduce FPS

Multi-GPU performance mode = Nvidia recomended.. ok for non SLI

Multi display/ mixed GPU acc = single display performance/ Multi display may give you more punch for some reason.

Power managment mode = prefer maximum performance

Texture filtering - Anisotropic sample optimisation = ON

Texture filtering - Negative LOD bias = clamp

Texture filtering - Quality = Performance ( or quality for strong systems with 1 GB + Vram video cards set at 1024 or set at 512 for lower Vram cards )

Texture filtering - Trilinear optimisation = ON

Force mip maps - Trilinear

Threaded optimization = ON

Triple buffering = ON

Vertical sync = ON

---------

 

Video cards that do not have 1 GB of memory use only 512 not 1024

ok, tuvm, ill try this :thumbup:

,but for now im satisfied with performance i already have

[jetace]

already fixed problem with stuttering , but for exchange of lower FPS,i just enabled V-sync and FPS become nailed to 60 , whitout matter of complexity of textures, moving objects.....

[theGozr]

Jetace, Yes Vsynch synchronise with your refresh rate of your LCD or CRT to 60 in most lcd cases witch actually will make your screen very smooth when panning around no tearing ( Track ir panning ).. :)

[jetace]

Yes, mate i know this, but i dont have Track IR, cose im using single 19'' monitor (16:10). My Track IR is x52por's second POV , and i hadle with it pretty good :)

[asparagin]

but i dont have Track IR, cose im using single 19'' monitor

 

you can use track ir with 3, 2, 1 and even 0 monitors..

I'm getting the horrendous stuttering as well. I fly LOFC 1.12b stutter-free with all settings high averaging between 25-35 FPS running at 1280X1024. I have a Intel Quad-Core at 2.5 ghz with 1 gig of video ram. FC2 on low settings (game looks poor and lacks crispness of FC1.12b on these settings) has bad stuttering. Nothing I've read on this thread seems helpful as a fix. I'm just going to assume that all the added features are the problem. Like others have said, the FPS is not the problem...it is the stuttering.

It would be great if you "tweakers" would release these changes in MODMAN form so folks don't have to manipulate lua's and .cfg's line by line.

I don't know if its possible to make a "one-fix-to-solve-all". Since stuttering some time occurs due to view distances it may need to make fine adjustments according to one's system and prefrences.

 

The basics is to tweak graphics.cfg. The settings may vary from rig to rig and from user to user. For example, I prefer mud-movers (Su-25, Su-25T) so I do care about the object visibility range while the F-15 pilot, who flies 15km above the ground most of the time chasing aircraft, doesn't care that much!

Try setting AA low. Run without "Fullscreen" enabled but at LCD native resolution. Enable Vsync in GPUs display properties.

 

Helped me with tearing @ stutter.

 

PS; isoul is right, its a matter of what you want to sacrifice.

 

Good luck .........Shad

Hi Viper,

 

It's very difficult to diagnose such issues. In many cases, the stutters may be related to specific OS or hardware settings and drivers.

 

Plagued by these Microstutters even with high FPS and sudden drops of 20-30 fps, i observed the CPU behavior and found out to my amazement that the cpu multiplier got into idle mode during flying (6 instead of 8).

I changed in my BIOS the multiplier from Auto to a fixed rate ( CPU aspect ratio) and after this the test mission Mig29 UAV was smooth with the same GFX settings.

 

It might be that this was just a glitch in my particular Firmware, but might help you too.

 

Still heavy FPS loos with overcast, altough i have the overcast mod installed. in fact, i didn t notice any difference. Was it the wrong folder??

Gamedir\LockOn Flaming Cliffs 2\Bazar\Effects\OVERCAST

 

The first explosion of an Aircraft causes also a FPS drop. Is there any way to set the value to medium like in FC1 ?

 

cheers

Vsync summary and final conclusion regarding DCS/FC 2

I can say with 90% probability that DCS Black Shark uses special Vsync implementation (wait for Vsync ?) that allowes to bypass Vsync limitation re FPS being integer fractions of monitor refresh rate so you don't need any tools for forcing tripple buffering (like D3DOverrider).

http://forums.eagle.ru/showthread.php?t=49651&page=2 read the whole topic to get a better idea

 

Why was Vsync needed?

 

 

 

Vsync has been eagerly discussed in the DCS forum section and the most important conclusion is presented on the fig above - D3DOverrider does diddle squat to DCS/FC2.

 

I dare to say that there is not much to be added to the discussion on DCS forum section. If you find some mistakes however please correct what's wrong by posting in appropriate topic containing misinformation.

 

 

 

Re general tweaking - this may be useful

Anisotropic at 16x as a green setting is a little bit over the top, I admit. I will change it to 8x in the next revision.

After days of testing I have found the soltion for stutters on my rig

 

I have changed the following line in the Graphics.cfg file

 

CloudAspectThreshold = 0.00;

 

This makes it realtime and has elimiminated the stutter and on my rig I do not see any FPS impact

 

Try it and see if it works for you.

 

Note on my machine which has windows 7 64bit there are two graphics configs. I needed to change the one in the following location (which is hidden by default)

 

C:\Users\JP\AppData\Local\VirtualStore\Program Files (x86)\Eagle Dynamics\LockOn Flaming Cliffs 2\Config\

 

and not the one in the normal C:\Program Files (x86)\Eagle Dynamics\LockOn Flaming Cliffs 2\Config\
