So previously I've always suggested having at least a 24 GB page file for Tarkov, gives windows enough space to dump as much as it can in to virtual memory to free up more RAM when you're only running 16GB. Turns out Tarkov doesn't care about your page file size, it will use virtual memory regardless of the amount of RAM you have installed.
I have 32GB DDR4 3600, left the page file system managed, then manually set a 32GB page file. Ran a couple of Shoreline scav runs to see what memory usage was like. Resource monitor screen shots. Commit (KB) is the virstual memory reserved for the process, Working Set (KB) is the physical RAM being used.
Opened the game, in menu, over 6GB Virtual memory reserved, 4GB RAM used:
During a Shoreline raid, 24GB Virtual Memory reserved, 9GB Ram in use:
After Raid: 13GB Virtual memory still reserved, over 7GB still in use:
I still have just over half my physical RAM free in raid and it still uses virtual memory instead.
