how much ramm do you need to run this game smoothly
i've got 8 gb of ramm but it still seems off time with things like the button clicks or missile launches ect

8GB is the recommended spec, but more never hurts. The complete recommended specs are:

OS:64-bit: Windows Vista, 7 or 8
Processor:Core i5+
Memory:8 GB RAM
Graphics:Shader 3.0 or better; NVIDIA GeForce GTX560 / ATI 6950 DirectX 9.0c or better
DirectX®:9.0c
Hard Drive:10 GB HD space
Sound:DirectX 9.0c - compatible
Other Requirements:Broadband Internet connection

Performance is a game of balance, in that you can still have performance issues if your GPU or storage aren't ideal - you're as slow as your next bottleneck. Even with a powerful PC rig DCS World performs better with some tweaks. Check out this performance thread on some things to try:

Isn't SSD recommended as well? It should be... I had 8GB DDR3 1600 installed but when version 1.2.7 arrived it simply wasn't enough. Adding another 8GB made a huge improvement.

I use 8GB RAM and a fairly good SSD, very rarely have any problems or hiccups with that.

The point of the SSD is to "solve" those cases where no amount of RAM in the planet will help you - loading resources from HDD. SSD's are actually not that much faster than a normal HDD in sequential reads ("only" about twive as a fast), but where they shine is random I/O - such as the game needing a bunch of different files loaded a little now and then in a mission. With an SSD the seektime between each of those files is dramatically reduced, since the SSD doesn't have to physically move a reading head back and forward over the disk.

More than 8GB of RAM will do little to nothing, unless DCS can utilize more than that which I doubt.

Even SSD won't make that much of a difference apart from shortening loading times and loading some ingame assets when playing faster, but to a degree that I wouldn't really call it an upgrade. I have both SSD and a HDD, tested DCS on both disks and I can tell you that when playing, the difference is almost non existant.

In my opinion today's games benefit the most from high end GPUs and CPUs, so look into that.

But it did... Both for me and the buddy I fly with. Monitoring RAM usage in multiplayer showed spikes that consumed almost every available bit of free memory. When this happend we experienced weird stuttering and short freezing issues. The additional RAM removed these issues completely. So it actually did quite a lot...

The issue is that these are issues that can vary a lot between computers, depending on what other services and processes Windows is running concurrently. In my case, moving from 8GB + HDD to 8GB + SSD solved everything. (Exception being some internal versions where other bugs were causing issues.)

The most common "load stutter" is when the simulator gets tasked to load effect files that have previously not been used in that game session, and (if pre-load radius is low) loading terrain elements in cities when you move across the map. In the effects sense, this can be most felt for example the first time in a mission you "lay down the law" with the GAU-8, and the simulator suddenly gets told to load the related effect files. Another co-conspirator to those issues can depend on what kind of memory bus you have on your graphics card - that is, first slow load from HDD, then treatment in RAM, then potentially a "slow" transfer to GPU memory bus.

Basically, my point is that even though it helped you and your friend, you cannot go from there to saying that it would help others without first checking out all the hardware and OS configurations etcetera first.

thanks guys its working fine now with 8 gb appreciate it :)

Went from HDD to SSD on my 8GB Ram system - huge difference in playability, so def recommended.

Of course more RAM won't add fps or improve overall performance. Performance has never been an issue for us since we use high end PC's custom built for gaming. What we experienced was some sort of memory leak when 1.2.7 arrived and adding additional RAM solved it. Period. Well, never mind... Go with 8GB.

8GB, but with the prices low more won't hurt

and El Hadji theres many who claim that more RAM or an SSD will increase performance, I feel as though these people just don't have a clue (for the most part)... however they will still spread that which i feel is misinformation around the community.

I'm no mechanic so I won't try to explain to someone why their car engine is making a weird noise and I wish people who didn't have a solid background in computers would stop telling people what will make the game run better. /rant

SSD may help if you suffer from hiccups because your disk is being a major bottleneck for when its loading a new section into the game (I've never experienced or even seen this problem before)

I have an SSD but short of loadtimes being quicker I never seen a single bit of difference in frame rate between an HDD install (using a slower WD green drive too...) versus an SSD install. what matters the most is video card and raw processor frequency (with at least 2 cores)

In your initial post it wasn't clear what exaclty were you refering to when you wrote "Adding another 8GB made a huge improvement.". By that it looked like you were refering to overall performance/fps increase.

Like Chameleon said, more RAM/SSD won't make much (if any) difference for overall FPS. They will only make a difference if you suffer from hiccups, long load times, micro-stutters, etc. as the data can stream a lot faster.

I updgraded from 8GB and a HDD to 16GB and an SSD, and saw a minimal performance increase in overall FPS. Even with every 64-bit game I play (including DCSW), the most I've ever seen a game use is ~4GB of RAM; the rest is just for overhead (Windows, background tasks, etc.) The performance was pretty much identical (except for the shorter load times).

If you don't have the cash to spend on an SSD but have the extra RAM, then a RAMDrive is also a viable option if you want to actually utilize all your RAM and get the same benefits

im happy i can run it with 4gb ram :D
Tatsue 15 kwietnia 2014 o 6:58 
One note that struck me, where going from 8 to 16 can help (but still only against load-stutters): windows preload. (It has some fancy marketing name, but I forget.) Basically, if you use an application a lot, Windows will start pre-caching resource files of that application (be it Office, Firefox or DCS) on bootup, and thus when you finally end up "requesting" those files, they've already been sitting in RAM ever since the computer started.

I'm not entirely sure, but I belive it should be possible to prompt Windows to pre-cache specific things (though it might require some tweaking on the service parameters or something). In that case, you can effectively get your complete DCS "precached" without needing a RAMdrive. But well, that's just a hypothesis, it's just a thought that struck me as I read the thread and I haven't even bothered googling it since... yeah... it's a bit over the top. :P
