    Hi Richey79 I benchmarked this for you with ArmA II Mark and there is no difference in load time nor cached time my ArmA II Scores are listed below.

    Cached Time being the 2nd run of the ArmA II Mark where you see the maps have been cached.

    ---------------Load Score------Cached Score

    RAM DISK------4371.39---------5260.66

    No RAM DISK---4379.70---------5260.42

    As you can see there is no change in performance. RAM DISK would most likely improve ArmA II performance if you load the full ArmA program into the RAM DISK how ever you would have to wait for it to load the full 8GB of ArmA into the RAM DISK and thus requiring more then 8GB of system RAM. Probably better just to set up a RAID 0 or install a SDD.

    You are right, only if u load whole game into ramdisk you will gain something.

    Why dont u try to install the demo into ramdrive, and see what u get. I would do that but i only have 4GB, and im not into upgrading my c2d sys....i wil wait for 32nm xeons, and 24GB of RAM.

    Hi zaira I do have some numbers I have worked with on visibility however I dont have them all compiled yet but I will share my raw data with you very quickly and if anyone else can help verify this i would appreciate it. if you are meaning Fill is the same as visibility.

    Visibility Benchmarks as to FPS penalty.

    This benchmark was done in a open field looking northwards towards a wooded treeline and mountains. Testing the impact that trees have on FPS. I carefully balanced the sweet spot to 60 FPS to give me a good scale and then increased in value until I reached a 2 FPS drop and then recorded the results. As you can see I found a penalty between 500 to 690 with 695 to 1260 being optimal and the drop in FPS from there. How this will scale with other systems and locations I have no idea. It was only to study the impact of Visibility on trees, how ever there does seem to be some changes to the vegetation in the foreground up to 50m I could not really tell if more was added or the vegetation was just turning or rearranging slightly.

    Vis. FPS Range

    500 55 penalty

    546 53 penalty

    598 57 penalty

    635 58 penalty

    695 60 1260

    1266 58 2370

    2374 56 2925

    2928 54 3300

    3301 52 4070

    4071 50 5020

    5021 48 5659

    5660 46 6375

    6380 44 7410

    7411 42 7865

    7869 40 8609

    8609 38 9415

    9419 36 9999

    Nice table showing clear corelation fps/VD. :)

    Could someone with i7 with 4+Ghz bench with this setings

    )rStrangelove;1399764']If a part of your ram is acting as a HD you'll end up with the game loaded into your ram 2 times. I can't see where this can be better for performance. :P

    You will end up with only a small part of game loaded 2 times. Arma 2 with everything maxed out uses less than 1GB ram (check with task manager).

    I know from demo that first time run has more stuttering than second, that implys that hdd is one of things that couses fps drops, and that game has poor mem management.

    Ram is cheep, if u have i7 you could get realy nice perf boost for like 200$ (cost of 12GB ddr3), and u can use that for more games and apps than just arma2.

    Even if u dont eliminate fps drops, u will get almost instant loading times.

    If u have 6GB you can test it with demo. And HDD IO is defenetly one (if not only) reason of fps drops.

    I hate stuttering in arma2.

    Could anyone with 12/+GB and 64bit OS try to install game on ramdrive.

    http://en.wikipedia.org/wiki/RAM_disk

    General concept of this is: u use part of system memory and create virtual hard disk that can be used just as regular hard disk, that is generaly 1000x faster than best SCASI HDD or 30+x faster than best SSD.

    Bad side is u will lose data when u restart but u can save image, some comercial programs even have automatic saving of data stored in ram drive.

    I tryed that with some smaller games i can fit in my sys mem (only 4GB), most radical improvement was morrowind , game that loaded textures in mem every 100m or so cousing drop in fps to 0 much 2 often. So i installed the game in ramdrive and no loading whatsoever, everything smooth.

    Aarma 2 has poor memory menagement, and there are shuttering coused by loading data from hdd to mem.

    Could anyone check this for me, even arma2 demo will work (demo has 2.8GB, arma2 like 9) ?

    I have only 4GB, so i cant try demo (2.3GB of ram is free on my vista x64 enteprise)

    If u are just a gamer and have 12GB of ram, you are wasting ram, you could use as cache.

    Thera are a lot of programs for instaling ram drive, just google it.

    This one has trial http://www.farstone.com/software/virtual-hard-drive.htm

    I used this one 2 http://www.superspeed.com/desktop/ramdisk.php

    Pls let me know did u benefit, cos im interesed what my performance will be when i get new system.

    Have fun :)
