March 28, 20179 yr Hello, although I purchased the 737 for p3D a while ago, I've retrieved and started using it more recently on p3d, mainly because having all PMDG products for FSXSE according to the manual, I set up FSUIPC to monitor VAS usage, and that trick is working perfectly on FSXSE, allowing to save the flight when I am around 200Mb from the memory ceiling in p3Dv34, instead, I suffer a percentage of OOM crashes (on approaches, of course, when the sim starts loading landing area), even with 950Mb to go (crashes ranged from 500to 950), so I am asking whether I am missing anything in p3d tweaking when flying airliners (it happens also with AS Airbus) - fresh Nvidia drivers 378.78 thanks (and sorry if I missed any reply in forum or manual) win10 i9-9900/ gtx1080 / Fatal1ty Titanium / 4x8Gb / Warthog / trackIR5 / 3Dvision / CH Throttle Quadrant / Saitek trim wheel / OCULUs CV1P3dv4.5 XP11
March 28, 20179 yr What causes the crash is not the lack of total available VAS but rather the lack of a large enough contiguous block of VAS. The VAS gets fragmented into smaller and smaller pieces as more objects are loaded into memory and subsequently unloaded. The sim does its best to clean up the address space but it is generally a losing battle. FSUIPC can also monitor the largest contiguous block of VAS but don't expect any revelations from doing so.
March 28, 20179 yr I had problems with this NVidia driver, rolled back to 376.33 and VAS usage was a lot more stable..Hope this helps.. www.avsim.com/forums/topic/503393-747-v3-steady-vas-increase-due-to-nvidia-drivers-not-747/ Derek C.
March 28, 20179 yr Derek beat me to it on the NVidia information. Stay away from 378.xx drivers. Although I've seen it happen, it is pretty rare to have an OOM with more than 600 MB of VAS remaining. Perhaps the scenery that it is trying to load has a lot of photoscenery? Those files can be 500 MB for just photoscenery not including the airport and objects. I recommend you do some troubleshooting; for example, start a session at that airport and note VAS then turn off the addon airport and start a new session and note difference in VAS. Dan Downs KCRP
March 28, 20179 yr Author my "high memory value" crashes happened when approaching uk2000 Heathrow v3 (+ Orbx's England), Paris Orly (+ FTX Global), Frankfurt v1 (+ FTX Global), with AS2016 trial by lowering a lot scenery settings, I have been capable to land ... win10 i9-9900/ gtx1080 / Fatal1ty Titanium / 4x8Gb / Warthog / trackIR5 / 3Dvision / CH Throttle Quadrant / Saitek trim wheel / OCULUs CV1P3dv4.5 XP11
March 28, 20179 yr Best VAS config for airliners IMHO is to just enable Take off airport and Landing airport in scenery. You can use Global and vector/utx but there's really no need for every airport along the way to load when you're in the upper atmosphere.
March 28, 20179 yr Author thanks, I didn't think about that win10 i9-9900/ gtx1080 / Fatal1ty Titanium / 4x8Gb / Warthog / trackIR5 / 3Dvision / CH Throttle Quadrant / Saitek trim wheel / OCULUs CV1P3dv4.5 XP11
March 28, 20179 yr I use simstarter to start. There you can disable and enable and do other tweaks then it's just to fly. Kind regards Mattias Nordgren PRO-ATCX BETA TEAM

Fantastic little program where you can turn on/off any airport scenery before you load FSX/P3D. This way, only two airports need loading and maybe a scenery when you fly over an area.
