After a few flights  with this tweak I am definitely satisfied that has made a huge improvement to my 777 flights.

 

Yes amazing and very happy with P3D performance FPS on my hardest test environment the London area:

With:

- Aerosoft Heathrow

- FTX Global

- FTX vector (only main roads and beaches :-)) huge VAS saver ;-)

- OpenEuropeLC

- UT2 traffic (with a lot of customizations)

- ASN

- ProATC-X

- PMDG 737 or 777 FPS at the gate 28 till 35 and on the airport moving between 28 and 45 in the air 60 and VAS is great in P3D now...

- FPS locked external at 40 in P3D unlimited :-)

 

So the advantage is if I move to a less demanding area my performance increases...

Thats pretty amazing

 

How do manage that kind of FPS with your system (GTX770,4,3GHZ) 

 

Could you post your settings please ?

 

Thanks

Forgot to mention. If we don't use fixed because of the pre-rendering hit, we should at least limit the top-out fps, as awf does here limiting to 40. My problem with that kind of setup is the flying gets choppy if fps drops to around 20fps. When instead I can set fixed 20 and get a smoother ride as the fps dips, and at 20fps, my fans don't make a fuss. GTX680, 4GHz 3960x.

It's all performance related in how the engine render and output the stuff to your hardware ;-)

 

Ant thoughts so far?

Optimize_Parts=1 worked for me aswell.

 

One thing to try for those who did not see a benefit

 

When I first loaded the NGX after the tweak, I saw no benefit and my frames were actually worse. But after I cycled through and loaded all my views I saw the same benefits as most posters to this thread.

 

The improvement in smoothness and fluidity is very apparent as well. 

 

Awesome tweak.

So, cycle through all the views?  Ok..will give that try....but the tweak certainly didn't take any FPS away for that matter, either.

Thats pretty amazing

Well I'm satisfied with my hardware performance (still not utilized my GTX 770 full with a reason)

(and over clocking performance bandwidth resistance on the buses etc...) lol and settings.

It's not useful to copy the settings because every system is different, it begins with the hardware then O/S, drivers, then software

installed background process etc... Sometimes a higher overclock can perform really worse as a well balanced one with less mhz ;-)

So many factors that contribute to the end result. even the screen resolution in use...

Happy to share my prepar3d config file just sent me a PM ;-)

 

Shots below at Heathrow one approach one just landing and one taxiing in to the gate 89 / 41 / 32 fps after the several tests locked my frame rates with the average...

40% UT2 but lot of customized traffic so the load is higher as on a default UT2 install....

Agreed Steve wise to do however the other approach is that my frames never drop to 20 ;-)

I was going to upgrade my 580, but i don't really need too. FB KIAD 34 FPS in the PMDG 777. Smooth all the way

Generally mine don't either but I see no need to leave it thrashing at 40fps to get a more consistent time between frames just by running it hard. The problem with this sim is that many, if not most, experience drops around 20fps if you go to the right places. Your shots show no better fps than mine in Unlimited. I can't see why you don't lock at thirty, specially with the desktop vsync of P3D.

 

The thing to do if you are going to get down below 30 is to ensure the time between frames is consistent, easy with higher fps.

 

I can see the changes on a CRT going from 60, 72, 80, 120Hz, but if it stays consistent It doesn't bother me. The fps range you demonstrate in your shots mean that looking around would produce way too much of a disturbance, just between 30-40 varying, and with TIR I'd be sick over my CH anyway. I just can't be convinced of your setup unless looking straight ahead all the time, and then the plane won't handle well, because of the frame locked to the draw rate. Nope sorry could not do that. Maybe with next years PCs, but even then I'll probably still choose the relaxed cool PC approach.

 

This graphic, shows my concern. A slower PC (960+GTX480) fair enough, but helps to demonstrate a heavy load in FSX, pushing it down to around 20-30fps. The top, no fixed internal fps, no NI limit. Underneath fixed at 15, limited at 15fps. With a faster PC try that at 20 or even better 30 if you can (if we have 60Hz monitor) and get your TIR on.

 

 

Steve, I think I found a sweet spot again here...

 

fps locked in P3D and NI at 30, Vsync: ON, Triple buffering: OFF

 

​using DSR 2x, 4x anti-aliasing in P3D and FXAA:ON... all other NI, CP settings default.

 

I'm a TIR user and I think this is the best so far.

Wel Steve and here we disagree while it's all theoretical, but my situation is different from yours hence from every build out there lol....

The demostrated FPS was not locked and for testing purpose with the new tweak in my most heavy flying enviroment to determine the best spot for my system and preference.

That's why I locked now external and certainly not internal, maybe going back to 35 where i was before still testing.

All I care for is quality and smooth performance, which I have here local and that's the only fact that matters for me nothing else ;-)

 

I don't use TIR because I find it personaly rather weird. (but that's probably me)

So I'm old fashioned via the different camera views and hat switches it works just fine for me...

 

If you want to lock internal with a fixed FPS and it works for you by all means go that way ;-)

 

Ps. we don't talk anymore about FSX because you can't compare anymore they are different.

 

Anyway back to topic....

 

Cheers,

I agree, the explanation could be better.

 

 

Thanks Peter, I appreciate you coming out just to say that! I'm not just writing code, as I have been doing my homework to produce real results for my clients. So I am passing that experience onto the AVSIM community which I enjoy a lot.

Dear Steve, I hope you dont mind getting bombarded with advice requests, however, may I ask what AM setting you would recommend for my new 6 core 5820K  CPU, its overclocked to 4.2 Ghz  Thank you !

You've got to set the system up to work with Fixed if you want to use fixed. If you found 30 too much, perhaps you need less, or something else is wrong, maybe try a new NVidia CP profile, or reduced settings. So it makes no sense to say it doesn't work, if you want fixed you need to make it work.

 

I have tried everything I can to get a smooth result that others seem to get locking frames. It just doesn't work with my system either and it is not exactly a slow PC. I am sure it is the fact that P3D doesn't run in true full screen so the whole locking fps at half refresh rate doesn't work. I would be more than willing to listen to anyone that has a similar system and gets smooth flight with locked frames.

 

I tried this tweak with the NGX and it did improve frame rates but P3D is still nowhere near as smooth as FSX DX10. The best result I have achieved is with Adaptive set in Nvidia Control panel, Vsync on & unlimited fps in P3D.

 

I have also just brought X-Plane and to be honest with a few free downloads the difference in the quality of the sim is night & day. Yes it has it's quirks but I have to say I am quite enjoying the FF 757

Mark - PLEASE don't take this the wrong way - my comment is general but you asked the question

 

Rather than just ask Steve what AM to use - try reading his post(s) to understand WHY he makes the recommendation and calculate it yourself.

 

"Give a man a fish and he'll eat for a day, teach him to fish and he'll never go hungry".

 

Apologies again if it seems like I'm getting on your case specifically, I just wonder why folks keep asking Steve when he's already given them enough info to figure it out for themselves.

 

Vic

Thanks vic old buddy!

 

Yes, we do have a situation in P3D whereby if the vsync is locked then we get momentary stutters as the old frame is displayed more than once, as the next frame is too late for the vsync. Less obvious in FSX with the partial vsync settings in fullscreen mode. Most of the time I get hundreds of fps, but taxi in a big airport, departure and arrival would chug like crazy on my setup with fixed 40, makes no sense to me. lol

 

I say again to those that don't get the best setup in fixed fps mode. Whatever you found, fixed mode is the principle mode for when your sim goes below 30fps, to maintain time between frames, you just have to try harder.

 

6 core with HT enabled gives a lot of options try:

4088=(11,11,11,11,10,00), 4084=(11,11,11,11,01,00),

3968=(11,11,10,00,00,00), 3904=(11,11,01,00,00,00),

2728=(10,10,10,10,10,00), 1364=(01,01,01,01,01,00),

2688=(10,10,10,00,00,00), 1344=(01,01,01,00,00,00),
