August 16, 20169 yr Hi, I have a geforce gtx 770 with 2gb vram and I'm using P3D v3.3.5. On every flight I have a high VAS usage (during takeoff approximately 3,1 gb are used, until landing VAS grows up to 3,8gb). While monitoring the temperatures of my procesor and graphics card I noticed that almost every mb of my graphic cards memory (vram) is used. The card has 2048mb and during the takeoff already 2006mb were used. Could it be possible that P3D (Windows) swaps the additional required vram memory to the main memory (VAS)? So would an upgrade to a 980Ti (6gb) or 1070 (8gb) reduce my VAS? Thanks in advance FlyingEngineer I am an enthusiastic flight simulator pilot from Germany with strong interests in aeronautics, materials science, engineering and programming. As I was just starting to learn English when I began virtual flying as a child, please excuse the poor English of my earlier posts (2015-2018) 🙂 FlightSim: MSFS2020 | JF BAe 146 Pro - PMDG 737-800 - Fenix A320 System Specs: ASUS ROG MAXIMUS VIII FORMULA - Intel Core i7 6700K OC @ 4,3 Ghz - ASUS ROG Strix GeForce GTX 1080 Ti OC-Edition 11GB GDDR5X - 16GB Corsair Dominator Platinum DDR4-2666 - Corsair Hydro Series H110i - Samsung 860 EVO 500GB SSD - Windows 10 Pro 64 Bit - CH Flight Sim Yoke - CH Pro Pedals
August 16, 20169 yr Windows does not swap vram and vas here. P3D will use as much VRAM as it gets. VAS is another different story. It is a 32 bit limitation and P3D v3.3.5 is okay with VAS (it isn't super fast in releasing memory but it is quite efficient when it needs to).

August 16, 20169 yr If the application needs more than the 2GB of VRAM you have available the OS will try to allocate any remaining virtual address space you have remaining. However, I rarely say my GTX 750Ti use more VRAM than about 1.6GB. I now have a GTX 980Ti with 6GB of which P3D uses about 2.3GB. Dan Downs KCRP
