Curious as to what y'all do to get the best framerates in P3D V5 VR. I have a Rift S and while I can get a steady 40 fps (1/2 the 80 max) with simpler planes, over really nice scenery I get closer to 20-30 fps in more complex planes like the DC Designs F/A-18E. Flyable, but jerky updates. Turning off automobile traffic helped a lot, and I haven't gotten around to replacing any stock AI yet so no added overhead there. Running OrbX PNW and the Drzewiecki Design Seattle City/Airports X. I realize I'm adding to things with the add-on scenery, but just wondering which settings have the most effect on VR performance so that I can enjoy the best compromise between performan…

So it will load from time to time but the majority resorts to p3d using less then 1% of the cpu and the screen just freezing. Deleting config worked once, did it again today and no luck, tried restarting and no luck. Edit: I am also loading up the F22 then the aircraft, as straight from scenario screen is 100% no load. Anyone got any suggestions as to why this would be happening / fixes? P3D is on a separate drive but I don't believe that would effect it anyway, or would it? Thanks ppl!

Does anyone know if there are any freeware, or reasonably priced inflight moving map type apps that would work with P3D, that are similar to these real world commercial products used by airlines: Rockwell Collins Airshow Betria Interactive FlightPath3D Honeywell Jetmap Panasonic iXlor2 These are the types of moving maps displayed on your passenger screen on long haul aircraft. I'm not after the moving map type that LittleNavMaps or other similar programs present, where the map remains at a set zoom level and just slowly follows the path of your flight. The InFlight map systems of the commercial products above, dynamically change the map zo…

I'm using some freeware ramp lights from some freeware scenery for KSAT the file name is ksat_p3dv4.zip With Dynamic on my frames tend to drop fps. With Dynamic lighting off frames are normal. These lights where origanlly designed for FSX and now in P3D they are causing issues. When I had FSX the lights worked fine. I wonder if its the way the format the texture files are in? Anyone have any ideas? I have several of these sceneries that use these lights and it would be nice to use them. Just need to know how to fix them in order for them to be compatible with P3D v4.

I seriously look forward to coming to this forum every day. But lately, I come to this forum hoping to see IF Lockheed Martin has released a new Hotfix for P3dV5! Can't wait. Today, I flew an Swiss Airbus 220 from Shannon to Liverpool. Took off from Liverpool enroute to Bern, Switzerland, to get my plane back to its Country. There I was, sitting by my computer, simultaneously watching TV, having a Stella Artois and a few German hard pretzels. It was fun and very enjoyable up until about 200 miles from Bern when I heard that sound interruption that signaled the sim was going to CTD. Sure enough, it did. About 1 in every 4 of my long flights ends this way. Up unti…

Today I downloaded and installed Windows 10 Pro v2004. To test I loaded up P3D v4.5 I had problems right away. The biggest problem was my frame rates which dropped to 4.2 to 4.3 . Ir is nearly impossible to fly with frame rates like that. So then I loaded up FSX Steam and it was running just fine. No drop in FPS. I have not seen where anyone else has had a big drop in frame rates with the new v2004. I need input from others who have updated to v2004, please.

Even when when surface wind at a given airport is stronger than 6 knots and I'm on landing approach with perfect headwind conditions, It happens that all AI traffic is using the opposite runway. It does not happen every time but often enough to be very annoying. For example, I'm loading a saved flight situation from YSCB to YSSY (2019, December 12, 04 pm) on landing approach for RW 16L Surface wind is from 154° with 20 knots, but AI is using 34 L/R runways and 25 runway. How can this happen? I'm using Active Sky (historical weather on), FT YSSY and ORBX AUv2.

Hi All, This is in v5. I have 2 airports (RJGG and RJAA) that display this light effect. Any ideas how to get rid of the weird yellow circle? Inibuilds dynamic lighting installed for both. Thanks in advance for the help.

I tested this P3Dv5 tweak with skepticism, but it actually does retrieve about 100MB of VRAM for those who are living on the hairy edge! Not huge, but maybe it will help someone before HF2...I'm running P3Dv5 HF1 under win10 2004. Save this code below as a batch file (VRAM.bat works nicely), then right click it and "run as administrator", preferably upon a fresh restart and before launching P3D. YMMV. taskkill /im ApplicationFrameHost.exe /f taskkill /im ShellExperienceHost.exe /f taskkill /IM dwm.exe /F Before running batch file: After running batch file:

GSX not worker for me in P3D v.4.5 . After latest update for P3D. 4.5, Windows 10 and GSX nothing happens when a push on Ctrl +F12.When I try start GSX on menu/addons the simulator is closed.I have , deactivate virusprogram, reinstall SODE 1.7.1 and update GSX after that but the problem is remains. What is wrong?GSX works in P3D V.5. Kjelle

Hi, Since some days I am missing a number of add-on.xml sceneries which were working before. I suspect the corrupted add-ons.cfg in C:\ProgramData\Lockheed Martin\Prepar3D v4\add-ons.cfg This becomes modified every time the starting P3Dv4.5 (4.5.12.30293) My backup add-ons.cfg consist of 83 well sequenced entries and is 11KB size. Whilst P3D start-up this becomes modified into a corrupted file with missing entries, starting with a block and entries [Package.55] and ending with [Package.82], followed below a new block starting with [Package.0] and ending with [Package.2]. The add-ons.cfg in C:\user\name\AppData\Roaming\Lockheed Martin\Prepar3D v4…

Hello: P3Dv4.5 latest HF w/ Saitek x52 joystick & throttle. Windows 10 1909 64 bit. I noticed that the sensitivity and null are grayed out. Control stick does display in devices and is working correctly. Any idea why it would be greyed out though? I've tried to remove device and drivers are saying up-to-date. Thanks.

I've been trying to fix this problem for a while with no success, In p3dv4.5 I am finding my faib and aia aircraft have nav lights that are way way to bright to the point they are like having white balls on the wingtips with just enough green and red to assume that these are navlights an not a glitch somewhere else in the ai. What can I check within p3d and the individual models that may be the cause of this. I have had the issue for a while, and thought by changing the models by installing aig ai manager and reinstalling my plans this may fix the issue, but alas not. All my other models are fine, both payware and freeware and the issue only seems to be with p3dv4.5…

Anyone using Asca? And how is it performing at 4k cloud textures? thanks mike

Should this be set to off? Or medium or higher? When using asp3d EA on? thanks mike

Hi, I think I should take action after loading time of Prepar3d5 grew over 12 min now. Here's my situation: I added FLAi plus the complete ORBX collection plus around 100 other aiports and stuff. No heavy planes so far. All this (and more, not yet installed into Prepar3d5) took Prepar3d4.5 around 5 min to load. Long enough but bearable. 12 min is beyond. The biggest step in loading time came with the complete ORBX range which I added via add-on.xml (into a "library") contrary to scenery.cfg in Prepa3D4.5. This makes me think that, perhaps, it's just the add-on.xml method making loading so slow. This is supported by occasional reports that Prepa3d5 and…

Hi All, Does anyone know of any basic software that will add head shake / turbulence for the Aircraft View (eg wing / engine view on the NGX)? I know there are complex software out there such as EZDOK and OPUS etc that might simulate this, but I'm not after a view changing programme such as chase plane, just something to modify the current default camera to replicate turbulence / headshake upon landing / breaking etc? Cheers, Alex

Was not expecting this as they stated they don't plan to port it over to v5.

Hi, I hope someone can help me. I have Prepar3d V4.5 having used earlier versions, FSX and FS9. I recently downloaded the X-Plane 11 demo out of curiousity. Obviously there are lots of threads comparing the relative merits of P3D and X-Plane. However the thing that struck me most clearly I have not seen mentioned before - X-Plane is much more immediately responsive to my control inputs than MFS and Prepar3d. In X-Plane moving the yoke to the right (for example) causes my C172 to immediately bank right whereas in the other Sims there is a slight delay. Is this just a symptom of a different approach to flight modelling or does it suggest that I have somethin…

Updated to the latest version via their Updater. Used the supplied Fuel Planner to load fuel; pax, etc; had the FPL in the MCDU all showing the legs okay in the left MCDU; went through all the Checklists sequences although I will admit I much prefer the UCGX pushback, for some unexplained tie-up with AS, only the GSX pushback will trigger the After Start checklist call-outs. Took off, applied thrust, climbed out..............and that's where the problems start. Despite setting a low initial ALT of 29000ft, followed the flashing above the speed tape to set THR CLB setting on the throttle pedestal, and then watched aghast, an angle of attack showing 20 degrees(have …

I bought a 1080ti last year and it dealt with the dynamic lighting performance issue for airports and aircraft. Well it's back again with the exact same scenario with dynamic lighting on. Anyone else experience this?

I recently purchased P3D v5. I'm sorry I did. Yes, it loads faster and has better performance on my 8 core ryzen than fsx, but it isn't compatible with much, regardless of claims of various developers. Kudos to ORBX and FSDT for making their products compatible and not tap dancing about needing to charge full price for a new license because it's a new platform. I will keep tweeking and tinkering, but I will put up with the lower frame rates of FSX.

Am flying over St Lawrence seaway eastbound of CYMX at 41,000 ft. Just seen what looked like a satellite/meteorite re-entry directly ahead of aircraft at elevation of + 2 to +5 degrees. Three white irregular fireballs moving left to right, very fast, trailing about 5 - 8 degrees. Duration about 1.5 seconds +/-. Does our scenery (P3Dv4.5) have these programmed in? Never seen anything like this before except in real life. Or am I losing it? 😲

Hello, when i load my 777 or 747 I get fully working cockpit but no outside model ( at least very broken). If you want a screenshot just tell me how to insert one please.

Hello, I am still learning FSLabsA320 and GSX. I have a question regarding the GSX process with FSLabs 320. I am using ATSU for all the process. My question : When i start powering the aircraft i activate PA switch + CAB. After few min i can hear cabin message welcoming pax on board while pax are still not boarding (i have still not request borading from ATSU) ! Not important, but for immersion...it is not the best.... When pax is boarding from ATSU menu i hear again the message at the right time. Could you tell me how you proceed to use it correctly ? Thanks in advanced Franck
