Hello. I know there are several threads concerning VAS usage. I also know PMDG rather staunchly asserts there is no VAS leakage with the 747. However, I thought I would start a new thread and toss in what I have discovered. I tried four times to fly from KABQ to LEST. All four attempts failed in an OOM at about three hours into the flight. I finally took the 777 and successfully completed the 10-hour flight. I got to thinking about the major differences between the 74 and the 77 and wondering why, despite PMDG's assertions to the contrary, the 74 seemed to be leaking memory. The major difference is the addition of ground service vehicles for the 74. Therefore, I determined to fly back to KABQ from LEST in the 74 but not request any PMDG ground vehicles. The only ground service I called for was ground power. This GPU is not drug into position by any vehicle. I did, however, use all the GSX ground services available. I successfully completed this 10-hour flight with no problems, though the 74 still seems to burn more memory than the 77. I obtained this information from the flight log files generated by FSUIPC. I did not change any of my FSX configuration settings between these flights, so I deem them negligible. What is important is that the FSX environment was the same for all three flights. I humbly submit the foregoing information for your, the forum's, evaluation. (I would have attached the three log files, but there does not seem to be a way to do this.) Eugene N. Kilmer
The Learjet (v2.8), as good as the model is, is an absolute VAS hog, so here are some tips for improving VAS conservation. 1. Use smaller textures. I've included some in my mod package. This is the best way to save some memory since MSFS creates a clone of the material (including textures) for every animation in a model. And the Learjet has a lot of animations. 2. Disable "High Resolution Virtual Cockpit" in FSX' options. This oddly enough yields about 200 MB of additional free VAS. 3. Lower autogen from "Extremely Dense" to "Very Dense". The extreme setting tends to bleed available VAS dry (not just with the Learjet, mind you), even despite running less varied autogen with lower res textures. 4. Disable flood lights. Yeah, you read that right. Despite Flysimware's optimization efforts, the flood light gauges still contain multiple dimmer stages which increase VAS use. Since these don't make all that much difference at night (console and instrument lights are much more important), it's best to simply disable them by commenting them out with "//" in the panel.cfg. Look for the lines containing "FLYSIMWARE_DIMMER!RADIOS_FLOOD" and "FLYSIMWARE_DIMMER!PANEL_1_FLOOD". While you're at it, also disable the completely unnecessary map light ("FLYSIMWARE_DIMMER!INTERIOR_MAP"). Nota bene: The next release of the mods will contain revised gauges for the lighting which will eliminate all traces of the dimmers. Other than that, the usual VAS saving tips apply, i.e. stay away from everything with high resolution textures (scenery, clouds, AI aircraft) or detailed mesh, save often and early, use FSUIPC to monitor available VAS, use DirectX 10 mode in FSX, etc, etc... With all VAS tweaks (except "high res VC" since it affects aircraft using 2D gauges), I took the Learjet on a tour de force along the East Coast in the afternoon all partied up (all lights on) with real weather (quite foul at the moment). Starting north of Boston at 11000 ft, I went south to the tip of Long Island and headed straight to New York City (which is Flight Simulator hell due to AI aircraft and custom scenery objects). Zooming across the city and EWR at 2000 ft, I climbed to FL220 and turned toward Philadelphia and onward to Washington, where I circled at low level (~3000 ft) before landing at IAD. I never dipped below 600 MB of available VAS during the two hours it took to fly the route. I won't dare to say that there are no VAS issues anymore, but it was a definitely positive experience with the aircraft.
Hi,, I have notice about the VAS very soon when i have installed the FSUIPC when it started giving me warnings every 10 secs,,, i am using P3D V.3 with: intel core i7 7700K win 10 64bit spited 4TB HDD 32 GB ram Formula maximums viii mother board x2 1080Ti msi SLI Enabled gaming x corsair H115I cooler ADDONS: Rex texture direct with soft clouds ORBX GSX Simbuddy FSUIPC RAAS PMDG 777 & 737 the message i am getting: HIGH VAS USAGE DETECTED: 3758MB (NUMBER CHANGING) - P3D/FSX LIMIT IS 4000MB (FOR 64BIT USERS) YOUR FLIGHT SIM MAY QUIT IF YOU HIT 4000MB) i have tried decreasing my scenerys and disabled all ground and sea traffic. Pls help,,,
