You can find lots of info on ramdrive usage from
this forum as ArmA2 has high visibility distances and thus many objects loading from hard drive to video memory at the same time and this is the reason for stuttering (but only sometimes for low fps).
I use this program to create a ramdrive
http://memory.dataram.com/products-a...ftware/ramdisk so far but will probably try a RAMDisk Enterprise when I have more RAM.
Out of 4GB RAM my ramdisk takes 1600 MB and this completely removes stutters for me having these 4 files placed there:
bob_buildings.SFS
bob_plane.SFS
bob_update.SFS
bob_update01.SFS
One of developers mentioned that bob_update.SFS and bob_update01.SFS are worth putting into RAM.
People at
Sukhoi forums report that the most frequently accessed files are bob_plane.sfs, bob_update01.sfs, bob_maps.sfs .
I hope this helps.
ps. My specs: i7-860@3.8, 4GB, ATI4890 2GB. Run mid settings at 1680x1050 at about only 25-30 fps low over land with about 30-40 planes due to slow video card but smooth and without any stutters.
Do not forget to exclude the ramdisk and il-2 steam folder from antivirus shields. And use Gamebooster to unload unnecessary programs from memory and defragment the game folder.
