New over spec'ed rig stutters????

[Spudkopf]

G’day all

My old desktop turned up its heels some 12 or more months ago with some major OS related issues, so I’ve had to be content with using the laptop and a keyboard to get my regular Il2 46 flying fix (if you can call using the keyboard flying that is).

And I’ve spent the last couple of 3 months totally rebuilding the desktop rig with the following:

Gigabyte Z97X Gaming 3 motherboard
Intel i7 -4790 CPU
Samsung 850 EVO 500GB M.2 SSD as the primary boot drive (C: drive, this also is where Il2-46 lives)
Samsung 850 EVO 250GB SSD as the secondary "simming" drive (G: drive, BoS, CoD have been installed here).
Western Digital 1TB Black as primary storage drive (H: drive, this drive was reformatted from old rig)
Gigabyte GTX 750 2.0 GB DDR5
Kingston HyperX Fury 16GB (2 x 8GB) DDR4 Ram
Coolermaster 700 W power supply

I made sure the rig was stably running on Windows 7 64x pro for about a month with minimal installations (CS6, Google Chrome, 7Zip, etc) just to make confirm that everything worked as advertised. Once satisfied with this I then upgraded to Windows 10 again running the rig for about a month to ensure everything was still OK.

So during the previous weekend before the one just gone I moved Il2-46 onto the new rig and flew around a bit (again only with the keyboard) and things seemed to be fine.

So this weekend I pulled out all the stops and re-installed my CH stick, throttle and rudders and after some initial teething issues got them operating back to more or less where I had them on the old rig.

(I'll need to make an edit and add the spec's for the old rig here for comparison when I get home)

Now on paper the new rig spec’s should not even break a sweat running Il2-46, but I am noticing some very significant stuttering (4.13.1 QMB - Do335 v13, Slovakia Summer, Target = Bridge, Weather clear, just me no other aircraft) even though I’m using the same settings (conf.ini, NVidia, in game – maxed out) that worked pretty well stutter free on the old rig.

I then re-installed Il2-Cod (now with all the TF stuff) and Il2-BoS, just to see how these sim’s performed and they seem to be as smooth as silk.

I went online to read through some related conf.ini threads on various forum sites and made the odd tweak here and there, like forcing the game to use the one core, and some other tweaks that to me were downgrades to what I already had, but thus far nothing seems to work, I even set the NVidia setting back to default just to see what happens, but this just made the stutters even worse, out of interest I switched to Direct X and all the stutter was gone.

One thing I have not tried is to try and fly Il2-46 from the G: drive to see if it is any different.

I’m at work now so do not have access to either my current conf.ini or NVidia settings, but does anyone have any suggestion as to where I should focus my attention or can point me to an appropriate discussion as to how to fix this?

Needless to say I'm a bit bummed out after having waited so long to get my Il2-46 rig finally back up and running.

[IceFire]

I'm betting is video card related. Especially after you said using the default nVidia settings made it worse.

Is the GTX 750 new or did that come from the old system? It's a little lower powered but it should manage IL-2 1946 no problem (you say it does BoS just fine anyways :)).

In the nVidia control panel setup a custom set for IL-2 1946.exe.

Turn off Antialiasing Transparency
Set Power Management to "Prefer maximum performance"
Set Threaded optimization to Off.


See if that helps.

Basically IL-2 is a very old game using OpenGL (even in Direct3D mode - turn that off BTW... go back to OpenGL), and it doesn't understand or work with some of the optimization and power controls that modern GPUs have. It has a terrible time with some of the modern antialiasing too. Go full out 8x AA but don't do anti aliasing transparency (that'll choke on clouds and fences in IL-2 for example) or anything fancy.

G’day IceFire

Thanks for the quick response, the GTX 750 was purchased some 8 months ago as part of the stock for upgrade, I would prefer to have get a GTX 950, but I had to cut build costs somewhere, so this is probably the weakest part of the whole build, yet having said that the GTX 750 should still be much better that than the old (and now W10 unsupported) Gigabyte 9800GT 1GB card that was in the old rig build.

The only reason I switched to Direct X was to confirm whether the issue existed across both Dirext X and Open GL platforms, as part of the fault finding process .

I’ll give your suggestions a go and see if this fixes things.

I’ve also found a thread over at SAS “Smooth, Stutter-free visuals in Il-2 with no screen tearing” for machine with very similar GPU, CPU, SSD and RAM spec’s and I have asked the author if he can send me his conf.ini and Nvidia settings as a further avenue into fixing this problem.

[Notorious M.i.G.]

Have you tried a map other than Slovakia? It's pretty system-intensive and some areas on my rig (mainly Trencin and Bystrica) end up with some huge framerate drops, which is a shame because it's a really pretty map.

As IceFire said though, OpenGL has really fallen behind DirectX through the years and it really suffers, but I guess that's the price we pay for the perfect water :P

G’day Noto….. M.I.G.

As I was able to fly this map on my old rig virtually stutter free, the problem must be either in the conf.ini or within the Nvidia settings or a mismatch between the both, I even used to be able to do this with the Nvidia settings set to the default, something I can no longer do now.

I did try out IceFire’s suggestions but these had no discernible effect, leading me to further believe the conf.ini may be the culprit.

So I tried running another copy off the dedicated simming SSD, which turned out having a different conf.ini as it was strangely set to a resolution of 640x480, not sure but the stutter seemed to be almost gone , so I quickly changed the res’ back to 1920/1080 in notepad then relaunched, but as I could only go for a very short flight as it was getting very late and I was well overdue for hitting the hey at that stage, I’ll need to go for another flight this evening to confirm any change in the stutter status.

What I think I need to do is get a fresh copy of a conf.ini that is optimised for best graphics results and see how this goes, as maybe I have an incomplete or conflicting set of flags somewhere.

On a parallel subject, where do I find the key assignments and are these able to be edited outside of the sim in notepad or another text editor? As I’d like not to have to manually reassign the controller buttons if I can at all help it.

Hi

Here's my config.ini open GL settings that work in-conjunction with NV Control panel settings I have tweaked just right for performance and eye candy.

Firstly if you have issues with these settings then somethings wrong with either the NV control panel settings or the power supply to the GPU is insufficient for the card.

Have fun and remember to back up your old conf.ini settings.

I had problems with the latest nvidia driver. When I was looking at ground textures I had huge amount of screen tearing, when looking at the sky all was normal, I've never seen anything like. I rolled back to 314.22 and the problem was gone. Reshade/SweetFX needs the latest drivers unfortunately. :(

Hi

Here's my config.ini open GL settings.........

G'day KG..... / VP.....

KG, thanks will suck 'em in and give it a try, however the entire situation may actually change over the weekend, as I sort have, kind of picked this up on the way home yesterday.....:grin:

Gigabyte GeForce GTX950 xtreme gaming 2GB DDR5, or as Jeremy Clarkson would say "More Power".

Now here's hopping that my current 700W power supply is up to the task, as I'm quite sure any further expenditure for an upgrade to something larger is not something I can even start to contemplate, seeing that I had to put up my very best grovel to the Minister of Finance to get my hands on the above.

Something I'm pretty damn sure She'll be making me pay for it for at least the rest of the month if not far much longer!

[Igo kyu]

That's a bit faster.

However, the thing with graphics cards is that the first number is generally a year or generation (Erm, I'm not sure I understand the current AMD card designations). So the Gtx 950 is more or less the current version of the Gtx 750. Looking at a comparison website, I'm seeing it as something like 25% or 50% faster, which is not to be sneezed at, but it's not going to be a massive difference.

nVidia are about to announce high end cards tomorrow, those will be eyewateringly expensive.

G'day Igo,,,,

I guess there are GTX750 and then there are GTX750, my current one is a GV-N750OC-2GL, which was relatively cheap and the cheapest 700 series I could find at the time I got it, and the idiom: "you gets what you pays for" probably rings ever so true here.

http://gzhls.at/p/1161941.jpg

I checked trough the comparison sheets and read quite a lot of review sites before settling on the new GPU, and the GV-N950XTREME-2GD is about the biggest Gigabyte bang that I can get for my very limited bucks.

Also the old board could not be SLI'ed where as this one can.

I would love to have been able to finance some awesome monster GPU's, but reality like gravity sucks:wink:

[IceFire]

The 950 should help. And your 700W PSU should be fine too... nVidia has made huge strides in the last couple of years to the point that my GTX 960 idles at far less than any video card I've had in years. It also idles with no fans and I can even run HD video and other stuff without the fan spooling at all.

Its also a pretty solid card even in the latest games.

Hopefully it helps your issue out. Not sure what else to suggest that isn't here from one of the guys.

700w should be well more than enough for a GTX 950. I have an EVGA GTX 950 SC+ and it only requires a 350w PSU (mine is 650w). The 950s with their new architecture are extremely efficient cards.

One thing you'll want to keep in mind is that different versions of the 950 have different power requirements. Some require a 6-pin PCIe plug while other 950s require an 8-pin PCIe plug. The stronger, more aggressively OC'ed versions (i.e. EVGA GTX 950 FTW) need more juice.

Also, make sure the plug you might have hanging loose is specifically labelled as a PCIe plug, not a standard power plug (6-pin, 8-pin, or otherwise). They're not the same thing.

[Spudkopf]

Turns out the power consumption is less than the replaced card as it took all its power from the pci-e slot, so was an unnecessary concern after all.

Now to the bad news, well the disappointment continues, however I seemed to have narrowed the issue down to the Nvidia settings, having all but ruled out any issues with the conf.ini.

I can run Il-2 46 stutter free if I disable v-sync, but I then I get screen tearing (especially noticeable at minimum FOV), enabling v-sync fixes the screen tearing, but re-introduces the stutters, even restricting the FPS to 60 as was suggested in the SAS thread I originally referred to at the start seems to have no effect.

Needless to say I'm getting a tad bummed out at this stage, and do not know what to try next.

[Spudkopf]

Ok after a weekend of frustration I may have solved it, by using the Nvidia inspector and selecting the following parameters and more specifically with the one highlighted below:

https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-xpf1/v/t1.0-9/13133111_1008581705892717_5704612064766429490_n.jp g?oh=6b3b8a4220d31e00a155b403a8254b94&oe=57A44B42&__gda__=1474031229_513b8bac8a0c9cfb16c1edcb8ebfa28 a

Went for several solo flights in numerous aircraft types using the Slovakia summer map with everything maxed out and with lots of clouds (even had forest set to 4 in a read only conf. ini) and it would appear thus far that I'm stutter and tear free, still need to see what happens when the sky is a tad more busy but thus far things seem to be OK.

[Spudkopf]

Turns out that the stutter has not been completely eliminated after all, did some more flying and noticed there is still the periodical micro stutter, however these are more noticeable when your just tooling around and admiring the scenery, however when you've got more important things to do, like attacking a target or when your focus is preoccupied with landing your crate, then they are less noticeable.

Now I wanted to tax the current setting somewhat more, so I set the weather to poor, as to bump up the amount of clouds, and still need to try the same flight again with better weather to see if it was the additional clouds that introduced said m-stutters.

With any luck there is still an ideal setting hidden somewhere within the multitude of flags found in the Nvidia Inspector and hopefully I can find it before my will to do so expires.

[Music]

Great read, even a surprise new Video card, and anticipation on whether it would work.

I'm having the same problem. I will try out the suggestions, though I have a ATI card. Have tried every official driver issued for this card, all the same. Choppy video after a few sec, and then clean, then choppy for longer than clean.

Started seeing it when I was drifting off to sleep.

I only have a computer for the flight sim, all the other stuff is nice, especially the DAW feature.

I was thinking it was time to just throw a few or three hundred into a new box, but this thread shows even that might not work.

I'll come back if any thing here worked, or had a adverse effect.

Cheers! Hola! noka!

[Spudkopf]

Hhhhhheeeeeelllllpppppppppppppppppppp

Had not flown for a while and after reading Osprey’s He 162 Volksjäger Units, I wanted to take one up for a jaunt.

Well turns out that the stutter issue decided to raise its ugly head again with a vengeance.

In the most part after some investigation I discovered that this was in part due to the fact that my installed version of the Nvidia inspector was not compatible with the Win 10 anniversary update.

Once I got that sorted things where somewhat better, but still seemed far more stuttery than I remembered, even though I had I tried the trick of limiting the frame rate to 60fps so as to match that of the refresh rate, but this did not seem to work anywhere near as good as it had in the past and instead introduced very noticeably longer stutters.

So I began to think what would happen if I limited the frame rate even lower to say 40fps, initially this seemed to give me silky smooth results, but when I added other aircraft to the mission (me in a Bf110 v 4x PE8) the micros returned along with some occasional very noticeable mega stutters.

It really beginning to really bum me out and taking the some of the joy out IL2 46 for me, my rig is so over-spec’ed for 46 that this simply should not be happening, I’d punch more RAM into the system but I doubt that this would have any effect nor would getting a second card to SLI (as my card is now discontinued this option is almost unavailable one anyway) , I’m now I’m looking into affinities and the such to see if this can fix this but every step forward seems to push me just as many steps back.

I’m getting close to my wits end, and on top of this I now having this Joystick reassignment issue to contend with.

So any, and I mean any suggestions no matter how seemingly mundane at this point would greatly enhance my chances of retaining what little of my sanity remains.

Just to recap my rig is as follows:

Gigabyte Z97X Gaming 3 motherboard
Intel i7 -4790 CPU
Samsung 850 EVO 500GB M.2 SSD as the primary boot drive (C: drive, this also is where Il2-46 lives)
Samsung 850 EVO 250GB SSD as the secondary "simming" drive (G: drive, BoS, CoD have been installed here).
Western Digital 1TB Black as primary storage drive (H: drive, this drive was reformatted from old rig)
Gigabyte GeForce GTX950 xtreme gaming 2GB DDR5
Kingston HyperX Fury 16GB (2 x 8GB) DDR4 Ram
Coolermaster 700 W power supply.

Well, it's been a few months.

i fought with that last Computer for most of that time. i found when i took a shaving brush, (the one they use to brush the shavings off your neck), to the Processor, not a lot of dust came out, but game ran smooth.

And continued to for a few months. then it started again. So I took the brush to the Processor again, and things smoothed out.

The third time was not so smooth, the computer wold not turn back on, and power supply was indicating a short somewhere, so itook every thing apart, and ended up needing a new computer. lol :c)

New comp is much better, no problems from day one, and Il-2 Runs smooth. It did reveal that the last one was shot, it whined like a Merlin all the time, which I ignored, and buddy obviously sold it just before it died.

So all is well with Music and Il-2.

If you are having problems, find a proper way to clean the processor, and hopefully that will work.

Happy New Year! Pilots
