BF3 is pretty RAM intensive, still.

post #1 of 62
Thread Starter 
Dunno what the patch was supposed to do but this game still eats into 1.5GB territory straight away. I looked at my second monitor and saw that I had 300-200mb RAM left when I hit a lag spike. Good job I'm getting 8GB later this month but wow it's hungry.

Anyone else get this? Is it just me?

I am getting the same usage, but with 16GB of ram it's not a worry. I still think it's a bit excessive however.

I hit ~ 4.6GB after 20-30 mins of playing.

Go to: Origin Games --> Battlefield 3 --> bf3.exe --> right click --> Properties --> tab to 'Compatibility' --> Check 'Disable Desktop Composition'

Saves about 500mb of ram...

yea bf3 is ram intensive. afterall it's a 64-bit application.
highest i've seen is about 1.8 GB exclusively for bf3.exe

I don't play BF3, but my opinion on game memory usage is that they don't use enough. Games should give you the option of caching graphics data in memory if you have enough to do so, instead of making the game engine go back and forth to the HDD/SSD to get data during gameplay.

Lazy programming that doesn't use what is now commonplace in the hardware is lazy.

I've never seen my system go over 3.5GB while playing bf3 and it never hitches and is smooth as silk. I don't know why you guys need so much RAM...

I'll give that a shot and see what that does.

Wow, 4.6GB? That's pretty crazy. I agree, though, if the game needs it and it's there it should use it, but it could do with backing off if there isn't a lot of RAM on the system... I saw the other day, though, that RAM is £20 for 4GBG of 1600MHz DDR3. So I'm totally grabbing 8GB in a couple of weeks when I get paid!

yerp, here in the US you can get 8GB of ram on sale for $30 or so (Google says 19 Pounds Sterling)

That would be a terrible idea. Caching graphics into RAM would be a huge bottleneck. The game engine doesn't go back/forth - it reads what it needs from a HDD or SSD and caches files as needed.
