RAM requirement for HD Mesh v4

Recommended Posts

Hello,

I've just moved to XP11 a month ago, and wanted to try out the HD Mesh v4 for Australia and Asia/UHD Mesh v4 for Japan and NZ, but the minimum requirements state minimum requirements of 32GB of RAM. Is this really the minimum requriement or can one get by with 16GB of RAM as well ?

Cheers

16GB are fine for HD v4, but can be limiting with UHD, depending on the area you fly in, which planes you use etc.

I can only say that I never experienced OOMs with 32GB and UHD v4, I never tried it with 16GB.

From my own testing I can say that UHD Japan works fine with 16GB, so do the areas of SoCal that I tried. You will most likely run in performance issues (over mountains, the mesh is really heavy on the CPU) before you get memory problems. UHD mesh never used more than 12GB on my system - but I haven't used it extensively.

The UHD mesh is free, so there's no harm in trying it with 16GB to see if you get stutters when flying it.

It could depend on how many other services and apps you have running in the background too. I'm always flying with ActiveSkyX loaded, LittleNavMap running as a flight planner/moving map, and a Chrome browser with a bunch of tabs open including YouTube for entertainment during the cruise phase of a flight. With 32GB I've never had problems. 

If you're building a new system or upgrading a current one, it's always a good idea to throw as much RAM as you can at the system (within reason). At this point 64GB might be overkill, but 32GB allows a nice cushion for multitasking.

Thanks for the advice gentlemen. I currently have 16GB of RAM, planning to pick up another 16GB kit soon. I'm downloading Japan, and a SpainUHD tile and will test it and see how it performs on my system.

This will give you a rough idea. I have 32GB of memory and it very rarely goes over 20GB and that's when I am doing other stuff other than X-Plane at the same time.

Using:

  • Spain Ultra High Definition Photoscenery -SpainUHD- 2.0
  • ASXP
  • ToLiss Airbus A319
  • And a plethora of other plugins

I run HD and UHD mesh and scenery objects at maximum without issues with "only" 8 GB of RAM. They key here is a page/swap file with a fixed size of 16 or more GB to buffer any demands for additional memory while loading new terrain tiles.
