Not impressed at all

Recommended Posts

So yesterday I took the plunge and bought P3D v3 academic license in hope that it will run better and more stable than FSX DX10. How wrong I was.

Basically everything below 30fps is unflyable, it stutters like hell and FPS are worse than FSX even at lower settings + FSX still looks a ton better with Reshade.

 

I haven't tweaked my cfg so far, only tried affinitymask once and changed my settings hundreds of times without any noticeable difference.

 

My PCs specs are:

 

GTX770 4GB OC

i7 4770k 4,3GHz

8GB RAM

P3D installed on separate SSD

Win10 64bit

3 monitors 5980 * 1080

 

So far I have ORBX FTX Global, ASN SP4, Rex 4 textures, EzDok, FlyTampa Sydney and Majestic Q400 installed and did a small comparison with FSX as addons are the same.

Loaded up the Q400 at YSSY in FSX, 26fps, smooth as a childs butt. Same test in P3D, 20fps with stutters (28fps on 1 monitor, still unacceptable given the not so high settings).

 

My P3D settings are quite moderate, shadows only for VC and clouds 10km, no tesselation, no traffic, scenery dense, buildings normal, no water reflections, no HDR.

Yet the GPU is stressed at 100% but the CPU only 35%. I'm all in for a refund at the moment except someone could help me on this.

There must be sth wrong with your installation. Most of us P3Dv3.x user can run P3Dv3 smoothly. For example, I can fly from OMDB FlyTampa)  to YSSY (FlyTampa), FTX AU, ASN, MT6, with PMDGs 777. Experience is smooth with moderate to medium settings. FPS are between 20-25 which is fine for me as long as it is stutter-free.

Which specs and settings? I should also add that I only have MSAA at 4x, no SGSS. Also tried with HT off as suggested by others, no difference :sad:

I just bought the monthy dev license, and maintained it for 2 months.

 

I am back in FSX with the Fixer, but that's not because I didn't find P3D3 SUPERB!!!! It was  by far the most performant version of any of the MSFS / P3D versions I tried, out of the box.

 

The PMDG 777 performed much better than it does in FSX:SE with DX10 Fixer mode, and with ASN. I also used ORBX FTX Global.

 

The only reason I abbandoned P3D was because I am much more involved with DCS World these days, and also expecting the News from DTG FS, which may well revolutionize the flight simulation World in just a few days :-) after their first announcement...

 

But P3D3 was simply amazing in terms of performance and stability for me!

No wonder a 770 is trash, sold mine last week and got a 12GB Titan.  Hardware must advance with software.  You got left behind.  Most folks are running 980s or thereabouts.

The 770 is still a decent card. I've used P3D v2 both with a GTX 670 and a 970. The biggest difference was how the cards handled the shadows, as long as I turned them down the GTX 670 was fine. The 970 allowed me to turn them up a fair amount.

 

P3D v2/3 is still not that graphically advanced compared to contemporary AAA titles, though they are slowly implementing more GPU-dependent features. As long as it stays 32-bit though, it's not going to be able to fully utilize current-day hardware.

Sorry, but that's rubbish. I have a 2GB GTX 770 GPU, and it can run P3D v3.1 just fine at high detail settings, 16x AF, 4x MSAA, and 4x SGSS! You just need to stick to 1920 x 1080 resolution on a single monitor. There must be something wrong with the OP's installation, because his PC is only a fraction less powerful than mine.

Yea but he's trying to push 3 times as many pixels as you. I agree something seems to be off. OP have you tried running just one screen to see how the performance changes? Maybe your 770 is bottlenecking a multi monitor setup.

P3Dv3 @ 5980x1080 on a single GTX770...there is your problem.

 

Remember, this is NOT FSX. The rendering engine has been completely re-worked in P3Dv3 to take advantage of modern GPU's - especially with the Tessellation function.

 

If you have the funds to upgrade your GPU I'm certain it will make a huge difference.

 

But, as suggested above, try running just one monitor @ 1080p to see if your performance improves - if it does, then you can be fairly certain that the GTX770 just isn't powerful enough.

Ah, yes. I didn't notice the three monitors stated at the bottom of his list. Apologies to jfmitch for not checking that! At least we know a quick solution :wink:

Ok what you need to do when entering the program hit Ctrl-alt-del and bring up task manager,click the processes tab and find prepar3d.exe,right click and select affinity,then click all CPU's then click OK and enjoy p3dv3. It boosts me by about 20 fps and gets rid of stutters. Also go into your prepar3d.cfg and add the fiber time fraction =.1 tweak. Your 4770k should be able to handle it as my 4790k does just fine. I will say that the GTX 770 will be maxed out in V3 heck even my 980ti gets a good bit used. I only use p3dv3 for light planes amd biz jets as I find complex airliner performance (Airbus X) to be much lower in p3dv3 vs fsx dx10. Also why are you only getting 26fps in dx10 I get 40 in the Dash 8 in dx10? What tweaks do you use?

 

Edit: never mind I see your using 3 monitors, ever thought of just getting one big one? I'm quite happy with my 32"2560x1440p monitor

Hi Folks,

 

P3D v3.1 worked pretty well on my Sandy at 4.5 with a GTX570 - just went through the expense of an upgrade to a GTX970 and whike it performs a little better - it wasn't orders of magnitude better... I lock my frames at 28 and it seems very smooth and usable... No further interest in FSX...

 

Regards,

Scott

I have the same CPU and SLI GTX970SC but also FTX AustraliaSP4. What gate did do test at 1920x1080? (Dash8 Pro i am at 40fps at gate 55) high settings 8xMSAA 

P3DV3.1 is really so much better than FSX DX10.

Bottom line is FSX will probably perform better with older video cards, but P3D will be better optimized for current and future generations of video cards.  GTX 970 is probably the entry point video card for P3D if you want comparable performance as FSX.

That's because you probably don't use the resolution the OP uses. With my 1080i monitor I also hardly noticed a difference between my current GTX 970 and the GTX 980 Ti I once tested.

 

If the OP's GTX 770 is good or not totally depends on what you are trying to do with it. ;) In his case it obviously isn't. My GTX 780 is currently giving me the best flightsim experience I have ever had in my life but that is due to various factors, like the resolution I use, a few settings I lowered a few weeks ago and a few new addons I have. It simply depends on what you are trying to achieve and what you are looking at if a GPU is good enoug or not. Not a single currently existing GPU is 'good enough' on its own.

Bear in mind that's at FTs YSSY and DX10 always performed worse than DX9 for me but I'd like to stick with DX10 because OOMs are much less frequent. 3 monitors work just fine, GPU doesn't even come close to 100% half the time in FSX. The problem with 1 big monitor is I'd always have to crank up the resolution far beyond 1080p, otherwise it's a pixelated mess.

 

EDIT: On one 1080p monitor I get 8fps more and that's it. Still below 30, still stutters...

Maybe my card can't handle the load, but in FSX dx10 the card almost goes to sleep. I've seen other people with single GTX 980tis running P3D v3 at 4k res. nearly maxed at payware airports and PMDG aircraft at 30fps. If one GTX980ti can do that at 4k then why can't my GPU do it at 3/4 the resolution and low settings with a much lighter aircraft? That card maybe costs twice as much as mine but it never is twice as powerful.

I tested performance at RW34L which gives my performance the biggest hit.

I ran a 32"1080p TV before I got my 32"moniter to see if I liked the size and honestly I couldn't tell the difference in quality between 1080p and 1440p

Even FSX in DX10 mode can't match the VAS performance of P3D v3. At least, the boxed original version of FSX can't.

Yes, locking in your frame rate makes a Big difference. Mine is as smooth as it can be at 31 fps lock in.

Except we don't know What The Frak your System Specs are because some Avsim miscreant(s) either directly or indirectly;

 

1. Neglected proper back-up; Or

2. Decided to not display the data that is already in and still lives in our profile; or

3. Outright deleted system specs from our profiles database...

 

And if purposefully done, was/were derelict in their duty to the AVSIM community at large, by arrogantly, neglecting to ask our opinion about the efficacy of displaying our system specs.

 

Whatever the case, Shame on you Avsim....

 

The bottom line is:

 

The above statement is irrelevant because we have no specs with which to compare.

 

Cheers,

To the OP:

 

Frame lock and a proper affinity mask helped transform my vomit-inducing stutter-fest of P3D into a much smoother experience. See my tests on this.

 

http://www.avsim.com/topic/477057-a-frame-time-analysis-of-p3d-v3-effects-of-cpu-affinity-frame-lock-and-ht/

 

Also, something about the clouds has changed (for the worse) as the code further diverged from the FSX base. They really need some optimization as they do not utilize our modern video cards well.

 

Cloud rendering will eat your GPU for lunch. For example, my GPU will see about 100% usage with an overcast layer, and about a 60% usage in clear conditions. You do not see anywhere near a hit with FSX. I've confirmed this behavior with several members of the community, and the only solution seems to upgrade to a more powerful GPU at the moment (such as a GTX 970 at the minimum) to overcome the performance hit. I know that sounds ridiculous to upgrade just for clouds, but that is the reality of the P3D engine, and there is a reason many members here are sporting GTX 980s or more for P3D.

 

Some people will argue tessellation requires a beefy GPU, but I will argue the performance hit with tessellation is much lower than an overcast layer with antialiasing enabled.
