I run at 5880x1080 with bezel correction enabled - previously had a 680 GTX, now a Titan. I use DX10 4x SGSS, theres no shimmering that I can see. I get very good FPS. I typically use  only 4% on all sliders for Land and Sea traffic, no aviation traffic because I get that from UT2 and medium airport traffic( I think its the minimum for some stuff to show up in GSX) I run autogen on dense and scenery complexity on extremely dense. 

 

Regarding speedstep: The cores will ramp up when you actually start flying - but not when you are in the opening screen of FSX as it barely needs any power to show 1 spinning aircraft. Therefore you get a bad Procspeed number - This number does nothing but determine the initial settings when you start FSX the first time, you can safely ignore it. I recommend to leave speedstep on. 

 

For some reason on my system SGSS always increases the FPS compared to any other AA mode...it did with my SLI 480's and the 680 I had as well

 

When you use 3x screens you will find traffic is a real killer and it's one of the first places to lower some things without loosing Image quality. A good rule of thumb I use when dealing with NV surround is just simply take what you'd normally use on traffic and cut it by 2/3. Honestly the DX10 forum is a good place for info - need to spend time reading it and the guide.  It's just that you are a minority of a minority so you cant simply use anyone else's settings.

 

Wow you have the titan and 6GB.. good stuff.. what sort of performance did you get out of the 680.. was it 2GB?  

 

I didnt have traffic on initially.. that was only in my test at a lower resolution for fun (car traffic and boats etc).. I normally run UT2 but for now i have it off..

 

Do you find that even with full clouds and rain your fps hold steady at least 25+ locked at 30.. i'd have to assume so at least with your TItan.

 

With traffic off and some thick clouds with some rain and 4xSGSS i get somewhat tanked.. into the 14-18 range at KSEA for instance.

 

So i opted (for now) to just use the 4xsupersample mode in NI.. now at that same test in a C90.. looping around.. it hold 19-24 fps with full on rain.. there isn't enough shimmer for me to get super upset, though it could be better.. 

 

question is.. is it worth another video card swap just to switch to 4xSGSS for perfection.. maybe after a price drop if a 780 would do the trick i guess.

 

I've spent quite a bit of time looking at various threads on how to max out DX10.. some that claimed to have the magic bullet on weather and other situations like clouds.. none made a difference (for me).. but its likely because (you and) I run a very high resolution with the size screens we have.. or so it now seems.. for the avg person with 19's or maybe even 22's (though i'm not sure a 22 x 3 gains much in fps).. a few tweaks go a long way.

 

Curious you have the 3930k processor.. did you ever have the i7 2600k.. i show the base chip at default for passmark benchmark goes from say 7900 to 12,000.. wondering if there is a big boost in using that chip over the 2600k.. though again thats a price jump of $500+ 

 

I also currently have Autogen at dense and Scenery complexity now at the next to last notch which i think is extremely dense.

 

Either way, i tried overclocking the 670 and I showed no difference in performance.  Its still a big step up from the 5850 i'll say that much

I couldn't honestly tell you the difference because I'm not too sure on the CPU as I've never owned it ( Previous was a 4GHZ I7 920). I've never had very good results overclocking GPU's in FSX- Maybee 1-3 FPS at most so I don't do it. 

 

Are you using REX? I looked over the other posts and hadn't seen if you were or not? Some stuff in there can have a huge hit as well. 

 

You might try totally commenting out the FFT in your .cfg as well.

I have REX and AS2012 as of now.. my initial post on this thread reflected neither.. results were the same with clouds..  That was my test partition..

 

On my full blown one, i now have AS2012 textures installed.. clouds at 2048 not 4096.. and dxt1 compression on the others.. i wasnt sure i was saving a lot of fps by lowering to 2048 though..

 

Still torn between which set of textures AS or REX i like better.  

 

Removing the FFT would be the same as the default which is 0.33 or so.. increasing FFT from (0.05 initially or the 0.15 i have it at now)..doesnt that makes fps drop and blurries become less (if there were any).

i had things going smooth with all the above (4x supersample though).. suddenly today, even after a reboot.. i'm getting the dreaded your computer has run out of memory error randomly.. i never received this one in the past..

 

I've tried playing with swap file management under 8.1 (set to automatic management) and so far no joy.

Regarding FFT and why to get rid of it:

 

Some tweaks on AVSIM are outdated depending on which SP you have installed. Most people use SP2 or acceleration these days.

 

FFT tweak was prior to SP2, have a look at this-

If you were to delete your fsx.cfg and let it rebuild it wouldn't be in there anymore(if you use SP2/accel)

 

Give it a try it may help

Thanks for the hint and the link. Very interesting.

PS: Just removed the FFTF parameter (was 0.12) and gained a little bit FPS (2-3%) and didn't see any disadvantage in the quality of the whole picture!

Ah nice ok thanks guys.. ill try this later today

 

Good find.

I gotta say though.. i briefly considered just buying the Oculus Rift goggles instead of an even better video card.. talk about immersion.. but with those i guess that makes my physical gauges i have useless, but if they worked, wow.. head tracking and all.

 In fact, we moved so many jobs off of the primary thread that there probably isn’t enough fiber work left to soak up the full time allowed by the default value of 0.33.

 

When the queue is full, we’ll allocate the full amount of time to fibers but when the queue is empty, fibers get no time because there is no work to do. If the rate of new jobs entering the fiber queue is bursty and the full time allowed for fibers is large, then you can imagine how this would increase volatility.

 

Further, setting it to values greater than the default value on single-core machines can increase frame rate volatility because it increases the amount of time we *might* allocate to fibers if there is adequate work waiting in the queue.

 

Well, back in 2007 when Adam talked about this (SP1 was the then current release), and most folks used single-core, with the C2D's just coming into service. It is a function with a parameter "built in" and part of the FSX configuration which is hidden, as are many other configurable functions. Putting it into the fsx.cfg is no different from controlling vertex buffers from within the fsx.cfg.  

 

At that time, 2008-ish, I had a C2D and running fsx SP2, and when test-flying at 3000 feet over KSEA, figuring out GEX and UT_USA/Canada and FScene, etc., - moving this from 0.33 to 0.2 made a huge difference in the smoothness of the sim, with frames moving to 23 from 19. I posted this here on Avsim, calling the mini-stuttering over Seattle "vibration", as that is what seemed to describe it best. It went from that vibration to smooth, and at the same time the lower I moved it the more the streets and ground textures went blurry. I was certainly able to move it to a "sweet spot" - regardless of any opinion from Adam, and can also repeat those tests today, as I did when moving to DX10, test flying around Vancouver Plus. Any heavy load will lower the frame rate, and depending on what is has the most impact - will create stuttering - and that stuttering can still be modified by lowering the FFTF. All one needs to do is to fly an F18 or other fast fighter-type aircraft close to the ground at 400-plus, and the ground textures will blur: move the FFTF up and the textures will normalize, but will then begin to stutter, and with lower frames.

Just adding a note here... an Evga 670 ftw is basically as powerful as a stock 680. Evga are the only brand to do this version of the 670 and they're amazing cards. If you get 2 of these in the 4gb version, then you're good to go. A single 670 ftw achieves 20-40 fps more than a 580 (generally speaking, not fsx specific). It's a BEAST. Since 7XX cards are now running cheaper, it's a great opportunity to open up ebay and find folks with extra $$$, who look to sell their 670 ftw / 680 for cheap in favor of upgrading. 2x 670 ftw over power a single 780 easy. Also, don't forget you can water cool them and utilize OC to squeeze even more power. Add another card (triple) and you will be good for a LONG time. On top of that, SLI is far superior to CF in terms of drivers and compatibility and it just keeps getting better and better.

Interesting.. i was considering a single 3GB 780 instead of my 2GB 670 FTW for 5760x1200.. your suggesting swap the 2GB FTW for a 4GB model (two of em, sli)?

It will outperform the 780 and you will have 4gb of bandwidth (more than enough for any current game) so yes.

I can see with the 4GB (each being 4GB).. my only thought was that the 780 runs at 384 bit I believe.. which would technically be better than 256 bit with the 670.. perhaps thats a non factor when SLI is introduced?

 

Looks like at least new, there are no 4GB FTW versions of the EVGA 670, there are a few 4GB regular 670's though, in other brands like this Gigabyte for $334 new.. ebay would be cheaper when buying two and selling one if so.

Non-factor really.

 

I'm pretty certain I saw a 4gb 670 ftw. Look good through evga's website.. it has many sub-models and it's confusing.

I suppose the FTW Evga 670 is a better bet than a regular 670, since it hits at a clock speed similar to the 680 i would assume?  Ill have to poke around and see what i find.. either way i'm betting the overall replacement cost is going to be around $600 used (net maybe $300 more bucs after selling the old one).  And yeah the 4GB 670 ftw is very hard to find used at this point.. one or two, short of an amazon used for a bit more at $379
