    Has anyone been able to get the latest SimLauncher version to work with v2.5? I wanted to give this a try to see if it would help with performance, but on startup I get a message that it's looking for a flight file in the Flights folder. Neither exist in the P3D directory. Any help would be appreciated.

  3. Have just downloaded and installed the new KSEZ scenery from Orbx. It is fantastic. However, in my setup, there are many aircraft and some static vehicles and people now appearing suspended in the air over the airport. I have installed the latest ORBX libs and also used the Airport Elevation Correction in FTX Global Vector. Any thoughts on how to correct this? Apologies, I am new to posting and I may have this in the wrong spot. Thank you.

    Taking advantage of the FSGenesis Easter sale, I purchased USA and Alaska/Hawaii, the question is what if anything should be disabled in ORBX or/and the Scenery Library for FSGenesis mesh to work. Alk/Haw installs into the FSX library so I would think it should be placed under ORBX. With USA being installed into Scenery-World-Scenery should ORBX mesh and custom folders be disabled. I have UTX USA and all west coast USA ORBX installed. Any help would be appreciated. Regards Echofox

  5. I've never had an oom in fsx but they are so common in p3dv2 I flew from Orbx KHQM to krnt in the Carenado C550 and then took off again and the OOM imminent warning from FSUPIC started going off but no OOM. I flew from a light payware airport to a default city and the damn thing almost OOMs. Why does LM do nothing to make memory management better ie dumping stuff that's way behind the plane ect. I'm sorry but there are many games that have way better graphics and are 32bit and have none of this oom BS.

    I am aware this is a well covered topic and I have tried following the steps in a number of youtube tutorials and threads on here but still no luck. I think im half way there as now when i start P3D i have the option to view EZCA World Cam and EZCA VC view, however there is no addon menu and I dont know how else to access the studio or make EZdok run properly? pressing shift +D does nothing either. I am pretty sure EZDOK config tool has deleted all my joystick view assignments as they dont seem to work anymore either. I used the migration tool and have now downloaded EZCA 1.18.5 Beta and followed instructions from here http://www.simforums.com/forums/ezca-11…

    I brought from FSX a habit of setting Affinity Mask in the configuration file. However, I saw some posts at the L-M forum that suggested P3D does it's own adjustments and I've been giving it a test. For dozens of hours now, I've been running P3D with latest hotfix and ASN beta with PMDG NGX and B77X aircraft and lots of Orbx scenery and FS Global mesh. The result for me is there is no perceptible difference between the optimum AF (254 for 4 core w/HT) and no AF. I was wondering if others have done this trial as well, just to ensure I'm not missing something obvious. Footnote: I have the i7-4790K stock clock 4GHz. I use process explorer to kick ASN off core 0.

In the past and by default every plane had it's own profile that could be changed independent of the other planes. Best
