    When I first installed v2.5, RAM use seemed perfect and didnt think I'd ever get to see OOMs. Only since last week I got trouble when loading a second flight and P3D ran out of available memory, with just 3.4GB RAM in use at that moment. This morning it got even worse. My first flight of the day, I just started up my pc and P3D, and like 5 minutes into the flight P3D ran out of available memory with no more then 2.2GB of RAM in use. The only thing changed in my setup is the addition of the Realair Turbine Duke, to which I added the Mindstar GNS (which was already on my pc for other aircraft). So I deleted the Duke, to see if this would make any difference, but it did…

    Need some input: My Saitek X52 is dead. I have always used a joystick just a throw back to my old CFS2 days. So my question is this which is better for P3D a joystick throttle combo like a X52 PRO or a Yoke and throttle combo. I Fly CFS2, FS2004, and am just getting into P3D. So I am looking for suggestions or opinions

    Hello i just installed rex into P3D, and well, the water looks like sh*t. Its squared, (literaly) too bright, and there isnt a way how to change it. I had this also in FSX, but i solved it there very simply, just used FS Water Config, which, obviously doesnt work with P3D. Soo.. any hints guys? Because this is extremly ugly. Screenshot -> http://i.imgur.com/EnkLljH.jpg I tried different themes, tried different settings, maxing up mesh and texture resolution, nothing changed. It looks nothing like on REX screenshots lol.. soo.. anyone?

  5. Hi All, I've tried to install the CLS MD80 into P3D v2.5 (w/current hotfix applied after initial install, prior to any add-ons) with the EMT. The plane will load, but there's no panel displayed in either VC or 2D. I fly exclusively in the VC as I have a triple monitor setup. Has anyone else encountered this problem? I haven't tried the LHS Maddog, as I've read it won't work. (How I wish it would be updated to work in P3D!!) Thanks for any help/ideas, Jim

    ok, this is a very strange thing. it happens to a friend of mine and to me also: after about 45 minutes, the frames decrease in P3D 2.5 (with hotfix). So after about one hour we have (in my case e.g.) from 50-60 frames only less then 20 frames left. When we click then on "time and season" and change the time just for 1 second, the frames are back then. It also works if you open time preview, make absolutely no change and hit "apply" (and "yes"). The friend has a different system with different addons and also a different OS (win7) We can't both not see, what causes this and eliminated a few factors like ASN as example. So, we have currently no idea. …

  10. The reason for this problem may be obvious but it's eluding me at the moment! I have removed all controller functions under Controls but when they are enabled (with Control+K) which I do when I am not using TrackIR, the elevator trim moves to full down setting and can't be moved. Any suggestions are welcome. Thanks.

    Just a heads up if you haven't noticed it Well found this on web read below no wet runways or tarmac – also rolling cloud shadows only work if its raining on my rig – water animation is not working unless you 100 ft above the water Scenario You open P3D v2.5 at the menu you choose your settings, weather, etc… start the flight, its raining and no wet runway. Solution Disable the startup menu on startup, restart the sim and within the sim create a flight. Now you should have wet runway effect. or just change you p3d.cfg not to show start menu….. Please note this issue did not exist in v2.4 and I hope somebody can forward this to LM to get fixed.

    Hi guys, I´m currently gathering all information for a switch of my main sim from FSX ACC to P3D. I have a question regarding Orbx sceneries. I know they do have a sperate support forum over there but I´m not keen on registering there for just one question. Anyway, onto the topic: I´ve got several Orbx sceneries here with me, all on CD (remember that 5€-sale for every scenery at Aerosoft some time back?! ;-)) I know that they should be ready for P3D but I guess as I have the v1 on CD I don´t know whether this will work. Has someone done similar befor?

  20. Greetings, with my old AMD X4 955 i had noted the importance of increasing the frequency of the Northbridge while significantly overclocking the CPU Freq. Switching to the new I7 4790K I had understood that the most widespread opinion is that it is sufficient/reccomended to increase the multiplier and voltage to get a good overclock. I was not entirely convinced, given my previous experience, but I thought the new processors were simply different... I came to doubt that though, after reading some thread on Tom's hardware forum (i.e. http://www.tomshardware.co.uk/answers/id-2475409/overclocking-cpu-cache.html), infact i believe, that since overclocking cache does no…

    With v2.5 I gave P3D a try and installed it beside FSX on a separate SSD. Yesterday I made a flight over the alps and recognized the annoying cloud flickering in mountainous areas known from FSX. I thought this bug is gone with volumetric fog? I used FSGRW as weather engine (because ASN still isn't released) and cumulus01.bmp from REX softclouds. All other clouds are vanilla P3D. Also tested cirrus_overcast03.bmp from ASN (FSX installation) without no difference.
