Haha, I feel you :-D

The PC gets fried... Croatia, what a nice country. Too bad I visited it only one time until now... And I was drunk the whole week so I don't remember anything :-D

Greetings to Croatia.

Well, come again, maybe we can grab a beer ;)

Hi Jim,

It really isn't necessary to be running unlimited as, inevitably, this pushes the GPU usage, temps and fans towards an unhealthy sustained max. You will achieve an equally good experience by pegging frame rates at 30 (I set it at 31) and your GPU will 'thank' you for it while reserving adequate headroom for other stuff later. Use NVIDIA Inspector's graphing module (always on top) to monitor GPU activity and you will see what I mean. Currently I am testing with various in-sim settings and all sliders to the hard right (some you can, but not all) is inadvisable unless you can accept the penalties in performance. As with V3 you need to achieve a sensible balance. Certainly the 1080Ti allows us to do much more than before, including the provision of some additional useful, and effective, anti-aliasing options (4xSSAA works well for me without the need to employ SGSSAA in NVIDIA Inspector). 

We are, of course, working our way through the honeymoon period before, and perhaps inevitably, certain familiar realities will kick in once again.

I installed V4 yesterday alongside V3 and discovered from the word go that:

1) I don't need any manual tweaks in the configuration file,

2) I can run without an Affinity Mask,

3) I am able to enjoy a smooth and stutter-free experience with Hyperthreading turned back ON.

I do not use G-SYNC with Prepar3D V3 or V4. I do with everything else, including X-Plane 11 and Aerofly FS2.

Regards,

Mike

I do plan to employ frame rate limiting, but for the moment, I'm letting it run unlimited to see what it is capable running "all out" in different scenarios.

So far I am doing very well with my 980ti with 6GB. I have done some wrought tuning and I am getting better results with unlimited FPS at 30hz than I got with V3. I very rarely see the FPS drop below 30fps and its very smooth but I am seeing 6 to 7GB out of 8GB total used in my system Mem so my setting are definitly well into OOM territory if this was 32 bit.

Thats all with the A2A C172, ORBX SoCal, FSDT KLAX and ASP4 in low overcast conditions. now I don't have and won't have the sliders all the way over (some I do) but I would say that its an obvious step up from V3 as far as performance is concerned. I need to get the PMDG 777 into the mix to really test it.

If I see a good deal on a used 1080ti ill pick it up but I am happy with the 980 ti so I will probably wait till next gen.

There is no doubt though that we are now in  the territory where GPU upgrades alone will make a difference just like with other 3D applications. That was never really the case before.

I have a 970 4GB and I'm wondering if it's enough.  What do you have and how's it working out?

Greg,

My GTX 960 4GB is working fine but i am not pushing it yet. I am getting better frames in Pd3V4 with the same settings I used in PD3V3.4.

I just flew into KSFO from KDEN in the PMDG 747.  I have the 1080I.  Frames over the mountains were 70-100.  Dropped to 20-30 while landing and at Flightbeam KSFO with FTC NC I am getting 40.   I would have OOM in Ver3.  No bluries, no popping....smooth as ice.

Places that my 1080 ti doesn't like....? Heathrow/London is of course still a frame killer at near max settings (15fps) and i found out tonight that Berlin is as bad, though i also had awful texture loading problems there. Blurries and slow loading all over. I'm reinstalling Orbx Germany North again as it didn't seem to look quite right either.

I get bad blurries if I used affinity mask in the cfg.

Crazy that even with a 1080 ti nothing is better then. Dont know why P3D still dont uses the hardware. You also have a much lower graphic card temp at 15 fps then at 50 fps in lower pop areas?

I get even 18 fps with my GTX 1060 on Very High everything and all the other stuff in London/New York/Los Angeles. All pretty much the same.

That's because texture loading is all CPU. Just watch your CPU while flying :-)

On these areas with 18 - 20 fps? I have only average 40 - 60 % load over all cores. Temp is 39 °C or something so not a problem at all.

That's just not how it works. CPU usage is not an on-off switch of either being at 0% or 100%. Majority of the autogen rendering is done on Core 0, along with a lot of other things. However, it's still meant to spit out the rendered frame and have it sync up with the other cores, plus the GPU. Thus you might never see full utilisation. However, most people do see their Core 0 sitting at 90%+ with P3D. Autogen is some of the most process intensive stuff and it's the CPU that handles that, yet the game is poorly threaded. That's why major cities see a huge hit in performance. Your GPU has little influence on this.

Yeah sadly that v4 still dont use multi Core CPUs at all. Core0 90 %+ nailed, all other 5 Cores at 20 - 30 % lol.

I run a I7 4790K at 4.6 with a 1080ti at basic OC of 1962mhz and 5505 for the memory. Also use a 4K monitor 3840x2160 at 30hz. video drivers are 382.33. 16gb RAM at 2400mhz

In P3DV4, I have the autogen at Dense for all. AI is at 50/30 default. FXAA on. AA 4xMSAA, Aniso 16x, texture 1024. Vsync On, Triple buff and Unlimited.

Scenery complex: dense;

Autogen draw distance: high;

Autogen veg density: Dense;

Autogen building density: Dense

No dynamic autogen

Dyn reflection: low;

Level of detail : high

Shadow quality: medium

Shadow draw dist: High

Addons so far: Orbx regions, As dhc6, Realair Duke and Legacy V2. I am adding add ons one at a time and testing to see the impact if any.

At EGLL, I get 30fps steady, day night or evening. Temperature is in the low 50's and the fans are accordingly at 50%.

Still testing of course. I am still not pushing it too far: raising slowly the bar one at a time and rercording the results.

But as of now: 1621 EST June 4th, I have found a sweet spot which makes this simulator the best experience I have ever encountered.

Cheers

Is the oc number ones you have set in the gpu software or ones you see when the graph tops out?

Basic OC from the Asus Strix and taken from the graph (monitored constantly with Nvidia Insp.

I have a second set of OC when I use FSX: 2022mhz and 5905 on memory. It makes a difference in FSX only.

What I see is that V4 loads all cores to the max in some situations. Especially in cruise. 

On the ground it is still limited by Core 0 at 100%.

I can confirm that I have in cruise or around 10.000 - 20.000 feet at least sometimes 60 - 70 % core usage. So way more then on ground. But never get at 80 or 90 % if only for 2 seconds.

On the much lower end of things, I am running a GTX 770 with a pity 2GB of VRAM. Prior to installing Orbx and ASP4 I was getting a fairly stable 30 to 40 fps. The addition of these two products took a good 10fps right off the top end. The GTX 770 is running an almost constant 99% the entire time and Core 0 on my 4770K OCed to 4.4 Ghz is at 100%. However, the sim does seem to be running fairly smooth. 

I'll probably upgrade to a GTX1070 in a few weeks to try and push the IQ and fps up a little bit.

The important point is it seems that P3DV4 scales really nicely as long as you don't try to ask too much from your hardware.

Yeah, cheers PPO and all, i guess with my new card and the new code i've been pushing it a little, even still.. even dialling back a little yields much greater rewards in V4 and i guess i should still be realistic and simply dial back and enjoy the view at better frame rates.

Still, thanks for your feedback all. I gotta say it's never looked better... really looking forward to the Orbx airports and localised goodness that they bring...

oh, and p.s. all... don't be dis-heartened in any way... we're talking about London, Berlin etc here... with the sliders right up, shadows on buildings etc the amount of autogen is completely insane... crazy.... i'd love some kind of setting where it dialled down certain details as you got near or chose certain areas, cities etc.. this would be amazing.. dynamic detail switching. Food for thought....

I am pretty happy with my SLI GTX970. 

Have spent all day installing and doing some small tests in the PMDG747. 

Started conservative and ended  up with ultra water and most to the right. For now i have my 4k Monitor at 24hz and SLI is a must now. 

Real air legacy at FDST KLAX with FTXSCA and some 6% traffic is amazing. 

SLI do rock in P3DV4. 

Thanks Michael Moe

Wow KenG, another one brave enough to try this! I have the same graphics card, and really thought I would be pushing my luck too far even trying P3D4. I am impressed by what LM have done! It works (leaving settings at about what they were in P3D3) and like you I was getting rock solid 30fps with default planes, even with a heavy scenery add-on and non-optimized payware airport (NMG FACT).  Much sharper textures, better autogen display distance, no popping of autogen, and pretty smooth performance, all without the worry of OOM.

Strange though, when I got Orbx and ASP4 going, with UT2 (40% limit with FSUIPC5), I did not see the FPS drop you note, in fact Orbx seems to have improved FPS (and least in the Cape Town area). And that is with my I7-4770 at standard 3.5Mhz clock speed (since upping to 16gb 1600Mhz RAM I cannot get a stable overclock, but have not really tried too hard on this; want to get stable at stock and then use P3D as my non-synthetic stress tester. P3D using  25% of CPU with core 0 is at 100% as you say (maybe throttled by the card?).

Adding in the PMDG 747 had the biggest effect for me, dropping my FPS down about 5fps at the same locality.

One thing good about trying this 2Gb VRAM card is it seems to expose a definite optimization of VRAM in operation. As you say the card is pushing it at 100% pretty much all the time (temps stable at about 65). ProcExplorer shows P3D using 1.5 to 1.7ish Gb VRAM (other op-system progs use the remaining 3GB), but P3D4 does not crash out when VRAM is maxed under demand, like a rapid 360 pan around in spot view. It seems to throttle back P3Ds share of VRAM when it can, or as system progs need to up their +-3Gb share, and then recharges P3Ds share again (which I suspect is causing a very slight stutter at times). If one leaves the view static one sees Gbs used by P3D drop steadily back down from max 1.7Gb to 1.5Gb, and system progs (mainly Explorer and VideoUI) max out their share.

So for those with 6Gb and 8Gb cards I really do not think exceeding VRAM is going to be a big problem at all, unless you push all settings to max, which you will probably need 11Gb+ VRAM and 32Gb RAM to attain.

I really want to move to a 1070 ASAP, as I know its going to give me the rock steady performance I want with even higher settings, and is the best bang-for-bucks card I can afford. If only I could find one now! Searching my local IT stores, but out-of-stock, two months ago they were lining the shelves. They do have 1080 Ti, but OUCH (32000 in Thai currency)! Talk about temptation more extreme than the local ladies.
