Aaah Yes - that was the one. I saw it in January, but didn't bookmark it. I would expect that it's the same formula that MS would use in the creation of the sim. Why wouldn't it be? - it uses all the right parameters and the electronic logic is correct. The fact that similar formulae were used to construct that speadsheet on the DigitalThemePark site means that someone else thinks so, too - plus my own electronics background tells me tells me it's fully - more so, in fact than the current guessing that goes into the BufferPools buzzword - which doesn't take any known data whatsoever from anywhere, other than the odd tidbit from Phil's old blog. Buffers are normally used to buffer the input data coming from a hard drive suite - except in FSX, where it buffers the datastream going to the GPU. I will bet my bottom dollar that that same pool also buffers the drive data, and that with the advent of SSD's we have a new 'unknown'.

Yes, it's logical. It's also logical that many things in FSX should work as expected, moreover many things in Windows should work as expected, or logically as expected, but they don't.

Alright, let's wrap this up, it's a good point you pointed out, but since it leaves too many questions open, especially those on genuinity, I wouldn't like to rely on the correctness of those numbers. We can provide users with a chance to calculate, but I would rather do it with a grain of salt and an explanation that these calculations are guessed, rather than confirmed.

Hi,

 

Interesting topic. I also have similar PC spec to the TS.

Actually, I've already achieved good FPS with no AI Aircraft.

 

But with AI Aircraft set to 100%, it steals around 10 FPS down from my FSX.

Is there any tweak how to improve FPS with AI Aircraft on?

 

Cheers.

No Twasono. It's general performance. As good as you get it, AI is going to bring it down.

If you want, do following test:

Make a test flight which you are going to reload. A static one, not flying like default.

Then open FSX and load it once. Close FSX.

Set AM. Press load flight and measure seconds it takes to load it. Do that for each AM you wish to measure. I bet that fastest loading is going to be with 85 with HT on, and slowest with 14.

Okai I just did your test, wanted to try out 84 only to realize I was already using 84 from 1 year ago (bojote's tool still puts it @14!)

Anyway made a save at mega airport amsterdam with the NGX (Because that combination is the worst for my system)

Results:

Affinitymask=84: 58 seconds (even did this one 2x to see if it's consistent, second time: 57 seconds)

Affinitymask=85: 55 seconds

Affinitymask=14: 62 seconds

 

Guess you're right, gonna try and use 85.

Btw any other way other than usepools=0 to unload the CPU and load the GPU more? I'm so bottlenecked, the GPU is hardly working while my CPU is dying.

 

edit: here's my filtered (to useful stuff only) CFG, using with system in sig.

http://dl.dropbox.co...2961/fsxcfg.txt

Thanks for all the above info gentlemen. I lowered FFTF from .33 to .2 and it really cleared a lot of microstutters when landing and taking off, though it still isn't 100% perfect (say about 92%). Any lower caused side effects with my now aging system. I also use internal limiter @35, and TBM=100 and BP=0 as my only other tweaks and its pretty darn sweet right now...so back to flying!

 

I only fly GA, somewhat low and slow...confirmed prop head. IMHO the key is to tune for what/where/when and obviously everyones needs differ here. (Just bought orbx SNZ...now off I go).

Damn you. :diablo: :diablo:

 

:LMAO: :LMAO: :LMAO:

Yeah - that FFTF got an awful lot of bad press from some folk, but I was amazed by the result of lowering it down to .2 and suddenly getting 23 frames over KSEA - I think with the C2D at 3.4gig? - Makes a big difference with the newer hardware.. Did you try locking at 30, Rod?

@Lurker Cory!

What is your cpu clocked at, Cory? It looks like you're testing the right way, but I think you could do better with some attention paid to overclocking. For some reason your ProcSpeed looks wrong at 9622, as all the i7 2600K's (I think) are around 15505. It seems to me that we need a minimum of 4.7gigs to get to that Nirvana of smooth and stutter-free without any other bad 'stuff' happening. In your cfg - leisure boats and ships jump out at 35. I'd pull those back, also I would limit fsx inside the program, as I've always found it to be too 'jumpy' (if that's the right word": I always get random hesitations that I can not get rid of with it set that way. With the fps at 27, and T_Max_Load at 2048 the calc comes out with a TBM=87, which is where mine sits at this moment.

 

Thanks for the suggestions Paul.

My CPU is OC'ed to 4.8. For Procspeed, should I just delete it and let the program figure the speed out?

 

When I have some more testing time I'll take the best rates.

 

Thanks again for your help!

Mines 18390 for what it's worth. I5 2500k OCed to 4.5 (or 4.6, I've forgotten).

Thanks. I'll up it some more. By the way, where is that number pulled from? I'd like to know so I can have an accurate number.

You're most welcome, Cory! ProcSpeed.... I don't think fsx uses it for anything other than set preliminary settings, Cory, and was guessing that your proc was a bit slow, that's all. It's interesting that Bonchie's cfg reflects 18390..

 

The number is created when you run the sim for the first time.

My specs are oc'ed i7 with ht off to 4.2ghz

ssd hard drive

6gb ram

nvidia gtx580 with latest drivers, 8xAS 16xAF

win7 64bit

 

I want to run 4096 textures, and I've locked the internal frames to 30. Can you tell me what settings I should use to speed up texture loading? I raised tbm to 80 from 40 and see faster loading. Can I raise texturemaxload from 3 to 6? I have usepools at 0 and affinitymask to 14.

 

When I used the texture calculator, the sim ran really smooth but the texture popup was ridiculous. as if my system was bogged down by those numbers and could work harder. Black squares on the ground flashing when I was taxing, and panning in the VC made textures and scenery suddenly appear like terminal buildings, then take a few seconds after that to load the texture.

I guess the FSX install saw this speed before the OC. I set the number to a arbitrary number of 20K. I reduced traffic as suggested.

 

Same test as previous post:

1) FSX FPS limiter to 27: 17-21 FPS

2) FSX FPS unlimited: 19-26 FPS.

 

 

 

On a whim I went to Aerosofts Mega Airport LHR. Max of 25 there (min 19.2 with mouse activity).

 

26 FPS in KEWR, in the NGX VC without moving anything lower than road and boat traffic. I think I'm going to have to cash out!

 

I'll keep an eye on this thread, but I think I'm going flying (and back to lurking)!

 

Thanks again for all the help!

Nice!

Well..... let's see..

 

102.4 * (3 * 156) / 30 = 1597

204.8 * (3 * 78) / 30 = 1597

409.6 * (3 * 39) / 30 = 1597

 

To keep the maximum bytes/frame those are the settings.. To increase that figure you can certainly up on of the multipliers.. i.e. Bojote recommended the TextureBandwidthMultiplier (default 3) be changed in multiples of 3, so - try 6, see where it goes. You cab=n drop the frame rate, as there's no benefit to this magic '30' that seems a "fixture": I believe this should also vary in multiples of 3. So - down to 27.. Good luck, hope it improves - and post right back! Thanks, GU.
