    Hello to all!

    I'm using MSI GS65(8750H@~4.1GHz+ and GTX1070 MAX-Q) for playing P3D v4.2(1920*1080,  4096*4096 Texture w/ 16x anisotropic filtering + 8x SSAA, NO Mipmap+FXAA, everything else is default setting).

    I'm getting 40~60fps(avg. 45~55) with PMDG 777. Although 8750H is 6-core(12-thread), P3Dv4 always utilizes 100% in #0 thread and low % in other threads. GPU usage always reaches ~100%. This is probably due to the nature of how P3D utilizes the multicore CPU. Most of code runs on the first single core, and other jobs like texture loading runs in parallel cores, which isn't too much of problem, I guess.

     

    I have run some test.

    If I get the AA setting lower, GPU usage drops and frame is fixed at ~75fps(avg. 55~65fps) even if I get the setting even lower. 

    If I get the graphics setting maxed out, the fps is about ~30fps, but didn't lower the CPU usage. In usual cases, if the burden of GPU increases, that of CPU has to be decreased since CPU has to wait the each GPU's frame task.

    (#edit: P.S I could confirm this by lowering CPU clocks to 2.0/3.0/4.0GHz and do tests. The fps decreases very greatly, compared to the above test)  

    So it's mean that the CPU lacks power very much. More precisely, since the cpu usage of other 5 cores is low, it's about the single core performance(IPC*clocks with cache size problem).

     

    Today I heard about Dell's new XPS 15, which can be configured to have i9-8950hk(more cache(12MB vs 9MB) and clock(4.8GHz vs 4.1GHz) and GTX1050ti(I don't know whether it's MAX-Q(lower TDP == Performance) or not).

    I'm considering to replace my current laptop with this. But I'm concerning the performance of poor GPU(1050TI). So my question is this...

    Which is the better laptop for running P3D with above in-game settings between GS65 and XPS15?

    Yes. I have a MSI GT73 laptop... I7-7700HQ, 1070-8 gig, 16 gigs ram, drives are M.2. At home I have a Dell 34" 3415  3800x1400 (approx) plugged in. It runs P3d no problem. I have a lot of add on scenery, aircraft etc....my P2dV4.2 is over 350 gigs. Runs well. With the M.2 drives it boots up fast as well. I've been using laptops for flight sims since approx 2002.

    Can you tell me how much fps you get in FHD resolution? Or even better, can you provide me a in-game video?

    I'm considering to sell the desktop computer and replace it with 8550U/16GB(DDR4-2400 Dual-ch). Also I'll buy Thunderbolt 3 eGPU kit and GTX 1080TI for desktop for connecting to that laptop.

    The performance of I7-8550U about the same performance as 7700HQ(=desktop 4790). 

    The performance hit of TB3 eGPU is about 20-30% when using laptop's display and the fps is high. If using 4K external monitor, the performance hit is lower than 10% even when using GTX 1080TI.

    Also I think P3D doesn't really use multicore much, even V4. Also I saw 4790K(stock clock) has near fps compared to 8700k(stock clock), so even IPC/clock difference on CPU seems not to affect P3D v4 performance.

    So, how do you guys think about it? Can a 8550U+GTX 1080ti TB3 eGPU laptop deliver enough power to play 4K P3D v4 with rich graphic options and addons like PMDG/REX/etc.?

    If a program support N threads, it's best to use N-core product with maximum clock*IPC. 

    But I don't know how much thread P3D v4 supports.
    Also, it seems that P3D v4 always does most jobs on 1st thread only.

    So my option is three.
    1) 8700k
    2) 7960x
    3) 7980xe
    (All AMD products are excluded because of their low clock*IPC)

    If P3D v4 don't support >12 threads (well), then 8700k is the best option.
    But it seems many indicate that P3D v4 utilizes 32> threads.
    Since AffinityMask is 32-bit 1-bit flag variable, 7960x might be the best one.(since 7960x has more possibility to have more overclocked frequency then 7980xe)
    But! If P3D v4 actually supports more than 32 threads, or the threads are distributed on physical cores first then on virtuals, 7980xe is the best one. 

    So, what do you think which one is the BEST cpu for P3Dv4?

    With AIRAC 1710 + EDDF payware scenery, I noticed there's appr option call GLSX07L and many like this.

    I select that and turn on APP button, but it doesn't be localized.

    I searched the forum, it seems PMDG's all product(737/747/777) doesn't implement GLS capability.

    So why there are GLS options, just because of AIRAC updates?

    I've always assumed the refresh rate for the wxr was driven exclusively by the weather engine.  PMDG is only displaying the data provided by the weather engine, it has no control over range, accuracy or refresh.  HiFi has a very good support system, I recommend you ask your questions over there.

    Thanks for the advice. You mean the forum on their site, not on Avsim right?

    Well there's the answer. 90  nm is the maximum range Active Sky produces weather radar information. So that is all PMDG can display. 

    Ok. That's fine. If it desinged to be like that, I'm fine with it.

    But how about Q2? Any suggestion will help.

    The weather radar information comes from Active Sky and that will only produce weather data for the cloud draw distance you have selected. That defaults to 90 nm. You could try extending the cloud draw distance, ensure 'detail' is also selected in AS, to see if the weather radar draws more distant returns. 

    If you are saying AS's Map part, in detail mode the maximum range is 90nm. I already tried this but whether it's in detail mode or not, it seems that doesn't affect the sim's radar range.

    Answers to Q1:

    yes, the real 77W RDR-4000 radar does show information beyond 80nm range (so as the conventional wx radar on the older 777 models), however the wx information shown will not be as accurate as those shown within 80nm unless the storm is huge. And anything shown beyond 160nm can be disregarded in practically unless we can see it outside the windows.

     

    Answers to Q2:

    The refresh rate of the radar on the real airplane is indeed slightly quicker. 

    I wouldnt be too worry about this weather radar feature in flight sim at home. nothing beats the real thing. 

    However, based on your video, I personally think it is acceptable for a flight sim software at home from a pilot's perspective.

    And my guess is by increasing the reality of weather radar simulation would put too much stress on the software platform which may kill the previous frame rate of the game.

    I will just live with Q1 part if this simulator designed to be like this.

    But for Q2 I have seen many videos filming the weather radar on "PMDG 777", and those except mine works just like real planes.

    That says, my radar response is even slower than other's pmdg 777. In fact, other PMDGs' weather radar are just fast as real one which I saw on youtube.

    I have two problems with the weather radar, but I couldn't find it is malfunction or normal.

    1. Range

    The weather radar doesn't show any information outside of 80nm perimeter. But I know the real 777's weather radar is more capable than that.

    Is it normal in pmdg 777's implementation?

    2. Response time(Delay in between each sweep time)

    Previously I asked about it, but somehow that topic was removed. 

    I uploaded this video back then.

    There are delays between each radar sweeps that shouldn't be there. I checked several videos recording real 777 and pmdg 777's weather radar, and there are no delays.

    I reinstalled everything many times, and no help. I really want to know the solution to this problem.

    Reasonable price, decent performance. The Aerosoft bus is not perfect but imho, its the best balanced one out there.

    Yeah, I admitted it. So then, is there anything better than Aerosoft's A330 when not thinking about the price?

    For the time being, is it the best products with reasonable price? It seems they quite delayed it.

    How do you know anything about the quality of Aerosoft A330 before it is even released, while the preview screen shots look pretty good?

    I know the preview of VC is quite good and frankly, their current quality of A320's VC is also good.

    I pointed out the quality because their A320's implementation(not graphics, but system) is somewhat limited compared to fslabs's one, even though Aerosoft's products are always at reasonable price.

    I am pretty sure that the A330 by RWDesign and JarDesign are only for X-Plane. But you can never really have too many flight simulators unless you are working with a limited amount of storage.

    As Keith said, the RWDesign and JAR Design A330s are only for X-Plane.   In my opinion the RW Design model is of very low quality and the JAR model, while having better systems provision is also lacking in many areas and (to me) just lacks immersion and a feeling of realism. Oh and it's vastly overpriced for what it is!

    The Blackbox A330 - it's unfinished and whilst you can complete a flight with it (just), few would recommend it.

    Your best bet is to wait a little while, as Aerosoft will soon be releasing a A330 that looks fantastic according to their previews.  This will be for P3D (and FSX).

    Like I said first, I will buy X-Plane also but only if their payware A330s' quality are good.

    Will Aerosoft's A330 be the best quality than current A330s? It seems Aerosoft's ones are lack of quality and not implemented in many details such as failures.

    I post this topic since I currently own only P3D not FSX, neither X-plane.

    But since 2007 when I play FS2004 for first flight simulator, I have always desperately wanted good A330, closed to PMDG or fslabs a320's quality.

    I'll happily buy new simulator if there's a good A330 on that simulator even if it's not for P3D.

    During the time searching about it, I found these A330 variations: JarDesign, RWDesign, BlackBox Simulation.

    Also I know Aerosoft is developing new a330, and heard about Fslabs are going to develop a330 but it seems not going to happen soon.

    Which one is the best one? If there are better others, please share with me.

    Sorry about posting lots of topic at once, but I finally just bought simulator and this product and there's info that can't be found yet by searching.

    By searching some forums, I could gather a little info about realism settings and there's a recommended setting in the introductory manual.

    But the option "Enable gyro drift" is somewhat unclear and the manual also doesn't say about it.

    I know about basic theory about it and this product is also affected by this(it looks like to me). But I'm not sure about whether I check this option.

    There are some mentions in web but they are all different opinions.

    Someone correct me if I'm wrong but on the master fuse.psd in the paintkit, it gives the option to color/edit how these look. Of course, that get's put onto what would be for the 77W: "pmdg_777_fuse_1.dds" You should be able to edit the alpha channel there.

    Thanks! Helped a lot.

    The aircraft painter forum might be a better place for this...., I would assume that those antennas are not painted.  Don't paint antennas, they are probably just white and not metallic.

    Well, actually it's metal. At least for p3d v4 version(latest). I could confirm it looking inside dds.

    If you look close, it's metal, seems without any color.

    Perhaps you're expecting too much?

    I find the radar representation in the 747 and 737 completely satisfactory.

    You have to understand the 'weather' being depicted is a synthesis of the data provided by Active Sky. There isn't any persistent thunderstorms or rain out there.

    I find the sweep rate and update interval close to what I recall seeing in the real thing (737, in this case.) If I fly into the pink areas, I get pounded by turbulence. That's pretty good, if you ask me.

    Enjoy what's there and try not to overthink things is my humble advice.

    But on my plane, definitly slower than other pmdg 777.

     

    (2:40~)

    Above record shows pretty like the real radar, but mine doesn't.
