News for Prepar3d. Just saw on the Forum so quoting here : " There was a login page set up for V6 closed beta testers so yes, there's obviously confirmed to be a V6 in the works and V5 has reached end of life, which is why it's been almost a year since it received a major point release." Of course most of us are hanging out for MSFS, but should be interesting to see just what Lockheed Martin can serve up for V6. Our future is looking brighter. Mark S. Hey Mark, This is exciting news! I can't wait to see what the new P3D v6.0 can do and if it gives FS2020 a run for it's money. Jason and I have been working with a fella named Robert on an unrelated CDU project and he mentioned something very interesting. He says that he has been experimenting with using MS2020 to generate the outside visuals on one computer and is using FSX to run everything else for his 777 simulator on separate computers. I have no other details on how he is doing this other than he says he's getting very good results from the test flights he has done so far. He is going to be popping in the hangar soon to give us more details on how he is doing this. In the meantime, ponder on this and how you think he might be making this work! Maybe this is the answer to our problems and at the same time we will benefit from the best of both simulators. There is no sim better at generating the world currently than FS2020 and what better sim is there to run the Lear45 simulation than P3D? Is this possible? Certainly would solve the problem of creating a Lear45 for FS2020 or porting it over. Or maybe P3D v6.0 is going to be so good it solves all our problems! We will see. Ron, That is very promising news. For those unfamiliar, Worldflight kicked off this morning. It is a number of simulators around the world, flying a course that will take them around the world in 7 days. It has been going since around 1998 and raises money for charity. Our very own Eric, from the earlier days of the forum has even had a stint flying the Cockpitbuilders sim. So my point is, the best online live sim is the simfest guys from UK. I highly recommend everyone pokes their head in for a squizz to see how a very professional but fun 747 is run over the 7 days. They have always used P3D, but just this year they have converted to MSFS 2020 for visuals. They have 3 x 4K projectors and the three screens from 2020 are warped. I did here it mentioned that the blend is done by 2020 itself with the latest adding screens option. From what I have seen from visuals when they are at airports it is absolutely stunning. Have a look but try and tune when landing or taking off to see the visuals better. They prove that an extremely detailed sim can now fly with MSFS 2020. Onwards and upwards for all of us. Cheers Mark S. Thanks for the heads up Mark, will check this out ! Hi everyone, Speculation about P3D's future is hotting up especially with Lockheed Martin teaming up with Unreal Engine. Here is a youtube vid to add some credence to the speculation. Mark S. Hi everyone, I know this topic has dragged on for sooooo long but I have tried to scan the forums looking for gems about V6. Here is a recent post from Lockheed Martin Prepar3d Forum. This person, I believe, is a beta tester and has said; " Don’t buy v5.3. Be patient. I’ll say no more." He is also a Forum Administrator for the P3D forum on AVSIM. There is so much speculation, but the truth seems to be there is a V6 in the wings. It is expected to be possibly, somewhat, backwards compatible. To what extent nobody knows. The other issue is the third party developers have essentially, almost totally, jumped ship from P3D. I think V6 would have to be something special to lure it's once large supporter base, back from MSFS. Interesting times ahead for us all. I have just ordered an RTX 4080 to beef up the graphics for the three projectors. If very little change for the 1080p at least it is a bit of future proofing, with 4K projectors. I have mentioned in the past, P3D is very hardware intensive and cpu overclocking is definitely recommended. MSFS however will give you better mileage for your system. Cheers everyone and enjoy your building. Mark S. I can't imagine the outcome under the hood with P3D V6 temperature wise. I'm struggling to contain heat from intel i9 13900K in MSFS 2020. This thing goes into thermal throttling in no time and temps stay within 100C on all cores. I got new 3rd cooler on its way hoping to bring temps down to not more than 90C at full load without having to throttle down on CPU frequency. I was looking more into undervolting CPU to reduce power consumption which at this moment peaks around 280W just for CPU! Unfortunately, undervolting become restricted due to some security vulnerability. Now, what did you say about overclocking? Hi Maciej, What a timely post from you. Lockheed Martin dropped an update overnight, for me, and is V5.4. I'm just installing now on my VR computer and if all good will update the big guns in the Hangar. I am just trying the Client update only first. I'll report back as soon as all up and running and tested. Now to the Overclocking. I don't know what experience you've had with that, but I can tell you it can be a 'Black Art'. Everyone's setup is different and so the results one person gets may not suit you. I have literally burnt off many, many, many hours testing small increments in the bios settings to either have the computer freeze, windows won't start or all good, only to find out after a thirty minute flight the screen freezes. I have had quite a few utilities doing testing after each tweak with slight incremental increase in performance. Having passed, it is the real world testing like the very demanding P3D that makes it come unstuck. That is the real world. So what advice I have I got for you ? Disclaimer is I am no expert at O'Clocking so you go ahead at your risk. I have moved to AMD processors so can't specifically talk about Intel however the procedures are practically the same just either side have different names for the same setting. I'll start with a few suggestions now and add more detail if needed soon. 1/ Water cooled is probably the only and probably safer way to go. I say probably because there are always people on Youtube sprouting their air cooled success. 2/ Hyperthreading, ON or OFF ? I can tell you that OFF is supposed to make your CPU run cooler. Also I have almost cried the number of posts over the last 10 years that have extolled the virtues of ON or OFF. I will tell you in MY CASE that I have tried both and in my case ON performs better. If you O'C correctly your temps are not an issue. 3/ Ambient room temperature. I have a large portable fan that blows on the computers externally during summertime and will put the AC on if needed as well. CPU temps will get up to 82 C at worst. Now almost in Winter I do not need any fans and temp maxes at mid 70's C. Sizeable difference ! 4/ Overclocking boils down roughly to two types. Manual Overclocking. Usually through the Bios. I had my CPU locked at 4.65 GHz. All worked but performance in P3D could've been better and the temps started getting up when under severe load. There are programs that you can download that will automatically OC your cpu for you. They will test multiple options until it determines a stable setting. Only P3D will confirm that. That is an option however being Windows based what usually happens is windows will boot with the Bios settings. You will need to open your software program with the Auto OC settings and load them which may require a reboot. They, but don't quote me, don't change the bios settings for a good reason. If you have a setting that is unstable and you boot into windows, it will not start as it is trying to implement unstable settings, so you would be locked in a loop. So the auto OC is a safe bet as it will do the work for you. Other OC options are the software utilities that come with your Motherboard. They will sometimes come with a program that will auto clock or have preset settings like for example Turbo. That is another safe option to go. Undervolting. I have tried that with almost no stable success in my situation. You may get Windows to boot, all looks OK but under load performance not good. 2/ Precision Boost Overdrive for AMD. In Intel you have an equivalent I believe called IPM. https://www.tomshardware.com/reviews/intel-cpu-auto-overclock-performance-maximizer,6179-2.html In my PBO it is a setting in my BIOS, that individually alters the frequency of each Core depending on each one's load. It will also boost the GHz temporarily beyond the core's limit. So some of my core's will now reach over 4.9GHz for a short burst. This is what my settings are now as is set and forget. You have LOW temps because mine idle at 3.75GHz and boost to high 4's when needed and only that core so overall the CPU temps are kept down. When P3D is flogging it rarely do I see any cores hit 100% load and if so no more than a couple of seconds. It can also be a guide to whether you have your P3D graphic settings too high or you can go up a bit more. Install this CORE TEMP to help with seeing what is happening on the desktop. https://www.alcpu.com/CoreTemp/ Play around with the settings and you can have it show you the freq for each core. Very handy. Take in all that lot as I get back to P3D....................and please let us all know how you get on. If all else fails type in your processor, mobo and O'c into google and someone will have their settings for you to try, but be prepared to burn off TIME. Good luck. Making some progress. For both system stability and testing - Cinebench R23 For CPU tuning - Intel Extreme Tuning Utility With new cooling system for CPU (both old and new are water-cooled) I managed to get temps under full load under 100C (except for 3 cores). Once I undervolted CPU core by 50mV, it dropped to just a tad above 90C. Power consumption for CPU is at 314W but system is stable and is not overheating. Well the stability is a good sign. As you well know the temps still have to come down, even though your CPU is renowned as 'Hot chip'. For your chip here is one review from beebom.com The Core i9-13900K has an idle temperature range of 35 degrees Celcius to 45 degrees Celcius. While playing an intense game like Flight Simulator, the CPU went to 91 degrees Celcius, which is a good temperature considering Intel has basically made 100 degrees Celcius the new 95-degree Celcius. Thermal throttling happens at a strict margin, but if the CPU is not operating above 95 degrees Celcius, Intel will use that opportunity to make sure the CPU is using turbo speeds on as many cores as possible. Also, for most titles that don’t use the CPU as heavily as Flight Simulator, the temperature of i9-13900K was around 60 degrees Celcius at most. So if this review is correct, your idle temp might be a better bet on when enough is temporarily enough and the CPU settings might be close to acceptable. As for P3D V5.4. In my case I did not see any visual difference, however the memory usage seems a bit better when changing screens using the 'S ' key. Unfortunately, if you weren't told that it was upgraded to V5.4 you probably would know any different. We are really spoilt by MSFS. V6 better pull a rabbit out of the hat, i.e. if they want to get people back. Mark S.P3D V6
