Barabara 10 Posted December 3, 2013 Arma 3 uses a pretty crazy amount of vram, but how much is required to be able to play at 12k/12k settings? 6gb? 8gb? 12gb? Currently the only commercially available gpu's with 6gb of Vram are the Titan and Sapphire's 7970 VaporX but with new cards on the horizon from AMD and Nvidia I'd like to know what would be the more sensible investment.

ratszo 17 Posted December 3, 2013 As in 12000m. view distance & 12000m. object distance? For what reason exactly? Share this post Link to post Share on other sites
iceman77 18 Posted December 3, 2013 A blazing cpu would be a better investment for Arma. Share this post Link to post Share on other sites
tonygrunt 10 Posted December 3, 2013 My 2 GTX 680 4GB never passed 3GB usage, maximum was 2.8-2.9 everything max at 1440P. Unless going multi monitor or 4K resolution I don't think there will be any benefit in Arma 3 having VRAM greater than 3GB. Share this post Link to post Share on other sites
Grumpy Old Man 3546 Posted December 4, 2013 I guess there's currently no rig that could take on arma 3 with 12k/12k, especially with lots of AI calculations going on. There are quite some "Arma 3 on ultra/4k" videos out there, but none of them make excessive use of AI. Your best bet for the most liquid performance would be to upgrade to a current gen. i7 and overclock it, then upgrade to 16 or 32GB RAM and put arma on a ramdisk for smooth texture loading performance.

jgbtl292 0 Posted December 5, 2013 you need cpu cpu cpu ! 2 gig vram not more ;) more is for nothing ^^ and play you with amd system , you need more cpu - than the physic is than on your cpu and not on your gpu ;) arma can not handle more then 6 gig ram / vram ;) Share this post Link to post Share on other sites
Grumpy Old Man 3546 Posted December 6, 2013 2 gig vram not more ;) more is for nothing ^^ this is not true. I've seen arma3 use up to 3.7GB vram at times. Share this post Link to post Share on other sites
PantherAl 11 Posted December 9, 2013 I've hit 4.8gb once, when fooling about at the highest possible settings, with tons of AI (Basically spammed about 120 inf on each side with about 20 vehicles each at under 500m range from each other) having at it on the Stratis Airfield. Was only getting about 3 frames, as my CPU is only a 3820 - and lightly oc'd at that. I would second the calls for better CPU: When I built my system I cheaped out on the CPU slightly in order to get a Titan SLI setup, which in hindsight, I would have been better off with a 3970 and one Titan. :) Share this post Link to post Share on other sites
oldy41 61 Posted December 9, 2013 I presume we are discussing video ram? I am also interested in this, since I consider buying a new card and would like to know, whether a GTX 770 with 4GB against 2GB makes a difference. With less than 2GB video ram I think you e.g. do not get the option to use ultra texture quality? Share this post Link to post Share on other sites
kklownboy 43 Posted December 9, 2013 VRAM, this game needs minimum 3GB of it. thats for 1080p and up. Having a CF or SLI of 3GB+3GB or 4GB+4GB does not equal 6GB or 8GB of VRAM to Buffer. Its still only 3GB or 4GB. A Titan with 6GB , is the only card out (well real Quadros too) that has a the full 6GB for a Buffer. VD/ObjD is more about CPU~ power, but you cant use the CPU power with out the GPU power... Ingame Filters like AA and shadows etc, along with the Display Resolution are GPU and need as much as they need, which in my testing is 3GB~. Now 1600p is a different level, and AMD and Nvidia have different ways/HW to do some cool stuff, that uses all the cool DFR and SASO etc... I myself would love a powerfull 6GB card. I have maxed out my 3GB of VRAM at 1400p and would love to have more than I need for 1600p.. Next year or so... Share this post Link to post Share on other sites

Yup, amusing that computer 'experts' are still claiming 2GB is 'all you'll ever need' (maybe @ 1050P it is) but 1080P (and beyond) and VRAM usage can be very high (even A2 would routinely break the 2.5GB barrier at 1600P, and that is not a new game). I might switch to Dell's upcoming 28" 4K monitors (only caveat is that they are TN and not IPS but if they check out ok, I might dive in) when they release in early 2014 and that will only increase VRAM usage even more (4K will start to become much more affordable in 2014, no more of this $3.5K for a monitor nonsense). I still have Titans in my main box but I picked up some 780 Tis for my 2nd box and my only real complaint is the 3GB FB (A problem in several games, not just A2/A3). EVGA (and others) have announced a 6GB (and possibly 12GB) 780 TI but Maxwell is not far off and I'm guessing they will probably ship with an absolute minimum of 4GB (but more realistically 6). As Kklownboy says, 3GB is starting to be the minimum now (for 1080P or more) and will only increase. Edited December 9, 2013 by BangTail Share this post Link to post Share on other sites
