Is there any system in the world that can truly handle P3D?

[overspeed3 410]

One of them Cray computers perhaps?

Solution :

Fs2000 “As real as it gets..”

350+ fps 🤩

Yes there is a system capable of handling anything you can imagine inside of P3D, ask Rob Ainscough about it.. he might build one for you, if you really, really want it :)

Rob has a monster of a rig, that is true. But equally true is the fact that he posted already several videos over at YT showing the settings he use and guess what? Even on his monster rig, not all sliders are fully to the right with all possible settings activated.

Personally, I take the opposite position: yes, there are plenty of systems that handle Prepar3d pretty well, if you refrain from using everything on max. Those sliders are meant to be used, no? I found a pretty solid setup for me, providing enough FPS to have a very nice simming experience in most cases. If FPS drop to much, usually adjusting one or two settings instantly cure it, the most obvious ones being antialiasing and cloud draw distance in cloudy conditions or night time flying with DL on or autogen draw distance and density for any other conditions.

And, on top of this: due to the possibility to save settings in Prepar3d, you can quickly adjust the setup to your needs. In my case, I use a preset called "VFR flying" with almost all settings as high as possible and a preset called "Standard IFR" with settings reduced where it does not really matter if flying big planes in and out of heavy scenarios (such as shadow draw distance, reflections, autogen density etc.).

Well, there are computers capable of handling P3D, but not P3D plus an indiscriminate truckload of heavy add-ons.

If the CTDs continue, check your OC. I have a similar setup to yours and my G.Skill 3200C14 32GB on XMP keeps causing CTDs with the FSLabs.

Thats even without any CPU or other OC. Dialling the XMP down to 3000 seems to improve stability (still testing).

You might try leaving the RAM at XMP timings and bump up the Vram a hundredth of a volt or two.  Voltage regulation can vary across motherboards, so it's possible the RAM tested out OK at XMP on the production line, but your mobo's voltage is varying from that.  I have some very good GSkill 3600 CAS 15 that threw occasional errors in MemTest86+ at stock voltage....a 0.015v bump was what the doctor ordered to keep it stable at XMP.

You haven't see the latest of his videos? there were a couple of weeks ago.. he switched to a TITAN video card with lots of VRAM, the results were very impressive..

Thanks Bob, I’ll give that a try. I’m testing ok on Memtest for XMP, but apparently the FSLabs taxes the system to the point where I get CTDs.

Usually a couple of hours into the flight with an ntdll. Tried a full windows reinstall, all OC off (except XMP) and they kept occurring. Read about XMP being the possible culprit and have been testing ok so far. Even better if the voltage trick works so I don’t have to sacrifice performance and maybe even reinstate my CPU OC.

You might also want to look into VCCSA and VCCIO voltages. Motherboard and memory might be qualified, but the memory controller on your CPU is falling behind while running high memory speeds or tight timings and will throw 0x5. Give SA and IO a bump and it might solve your issues. Additionally, sometimes BIOS gets memory training wrong when it comes up from cold and dark. If you only do soft shutdowns, then those memory values usually remain until next power cut, when it will retrain and might achieve stable settings. That is especially true if your memory sticks are not in motherboard's QVL.

To get back on topic I think we are hitting a wall of diminishing returns with old poorly optimized architecture for modern multi threaded cpu’s and advanced video card features.

 

Until LM completely re-engineer this sim away from the original FS9 type architecture and update it to modern use and full DX12 compliance I think we are trying to make the proverbial brick fly!

 

So we can keep buying monster rigs for moderate improvement or...

 

We can hope MSFS 2020 rewrites the books so to speak!!!

I have seen them and it is still true what I wrote, even in those vids with a TITAN RTX, he has not everything on max. Most reflections are deactivated and also not all shadow cast and receive options turned on. Special effects on low, water detail on high (not ultra). Dynamic reflections on low. Cloud draw distance on 90mi.

As I said. If you put your settings right, a today's computer is capable of providing enough FPS to have a perfect looking P3D simulator experience. Besides that, the TITAN RTX is a VRAM monster, the pure performance is on par with the 2080Ti, the custom 2080Ti with factory oc are even slightly faster.

It amazes me just how much VRAM some of you guys are using in P3D, and it makes me wonder quite how my 2GB GTX 770 manages to run (for example) a PMDG747/ORBx TrueEarth Netherlands/Fly Tampa Amsterdam Schiphol combo without collapsing into a mini black hole! I assume that it must be stuff like dynamic lighting, shadows, clouds and 4K resolution that result in an exponential rise in VRAM usage?

When VRAM gets exhausted, your video card will be forced to switch to normal system RAM / Paged RAM.. causing massive FPS slowdowns / stutters.

[Christopher Low 5,354]

Oh, I get stutters......but not as bad as I would have expected in high detail areas with only 2GB VRAM. In fact, I seem to experience fewer stutters with that PMDG/TrueEarth Netherlands/Fly Tampa Amsterdam combo than I do in other areas that have significantly lower density scenery. Framerates do suffer when on the ground at Amsterdam Schiphol, but major stutters are surprisingly few and far between....

On a side note, this is why I need some nice person to, er.....loan me something like a 6GB GTX 980Ti. For experimental purposes. I would give it back. Honest!

So you've boarded a real Cockpit of a real plane like a corsair for just making this short video  ?  The poor pilots must have driven nuts .... .

I've read a newsflash on internet right now - and you may believe it or not - but this incident really happened yesterday in the air.  Nobody was'nt hurt; the crew and the passangers got away with no more than a fright.

But with the help of the pilots the investigators and police officers could make a composite sketch of this "sky-paparazzo" - the police are looking for any relevant information !

....and as you can see clearly, this guy looks like Salden literally; mistaken identity not possible

Thank God nobody wasn't hurt.
