At RAM Limit

[Jacky60]

Playing Arma 3 Beta multiplayer my RAM usage is at or over 2g per GPU on median settings. I was surprised but it's pegged at 7904-8015GB always suggesting the game needs more video RAM -more than 2gb. I do get hitches and occasional stalls which can be fatal.

Arma 3 is a bit of a weird one. It seems that in many cases it grabs hold of free VRAM regardless of whether it truly needs it or not.

In cases where you are genuinely running out and think this is causing performance problems, you can flush the VRAM via a console command.

See the second-to-last post in this thread, for instance: http://forums.bistudio.com/showthread.php?150453-High-VRAM-usage

Did it just spike to 2gb or was it regularly using 2gb? Problem with programs like gpu~z is that they report the max vram used, but they dont show u the avg ingame that was used.

It is pretty constantly up at 8gb (2gb per gpu) I'd forgotten about RAM flushing but even if I did I think the usage would just skyrocket again. I'd be curious to see a Titan's usage.

And people wonder why I bought 4GB GTX 760s for the 'lowly' resolution of 1680x1050.

Now, maybe, they'll shut up.

Many games (BF3 for example) will make use of as much VRAM as is available for caching purposes, that doesn´t mean that they specifically need all that RAM for stutter free play. Unless you´re seeing noticeable stuttering I wouldn´t worry about it.
