Does DA2 have a Memory Leak?

K, so I've been monitoring my VRAM usage in DA2.

Settings:
2560x1440
Very High (all DX11 options enabled)
4xAA
With the high res texture pack

And I'm spiking over 1.5GB memory usage according to Afterburner and GPUz. That's more than any other game I've played at this res, including Crysis, with it's crazy draw distances.

I've seen other posters mention it using over 1GB of VRAM at 1080p as well. Could that be part of the reason this game has performed so poorly on Nvidia cards (along with the driver issues of course)? Or is this kind of VRAM usage legit?

I mean the game looks "good" but all things considered, that seems awfully high for the quality of the visuals.

Yet its still far better than Crysis II which is quite possibly the worst coded game in the history of fail.

It's the console trend, perhaps both will improve with patching. I enjoy DAII, more so than DA:O... To each their own.

The game uses more vram than any other I've played yet, only thing that came close was Oblivion modded, which used around 1180 vram.

(1080p)

It's normal, runs like a dog on nvidia hardware, try the latest beta drivers, they didn't help for me but some report an improvement.

Yeah I'm using them now. My performance is actually pretty good with them, though I still get weird dips during cutscenes (when there's basically nothing going on).

It just seems odd that this game would require more VRAM than Crysis, Metro, even benches like Heaven at the same res/settings. It must be completely unplayable in surround.

There should be a Bioware patch coming soon to adress some of the Nvidia performance issues, not sure that it's gonna help a lot though...

AMD helped Bioware to code the DA2 engine btw, that's why it runs OK on AMD hardware.

lol im waiting for the youtube video of someone doing nv surround and it locking up...

anyways i also suspect a memory leak...seems awful high for a ported game.

Games today, DX11 especially, will take as much memory as they can.

So seeing 1.5GB at that resolution and 4xAA and DX11, its fine. What do you expect? 10MB of memory usage?

Also, GPU memory usage is not a memory leak. Memory leak (which is a programming language to a crap programmer) takes memory from system memory, not GPU memory...

GPU memory is based on drivers commands, so, unless 90% of the games have memory leak, its fine.

Obviously not, but that's more VRAM than a stock 580 has and this is just 1440p. That doesn't seem a little excessive to you?

You're running a higher res than I am. How does your VRAM usage for DA2 compare with other games?

I was under the impression that memory leaks referred to a program using memory and failing to properly free it up afterwards, leading to inflated memory usage. That applies only to system memory?

DA2 = Around the 1.4-1.5GB of memory usage.
Crysis2 = 1.3GB+
Mafia2 = 1GB during benchmark, 1.1-1.2GB during game-play.
ME2 = barely 600MB
DS2 = 600-650MB
WoW= 1.3GB during calm hours, 1.5GB during rush hours in a busy area.
DCUO = 700-800MB
Rift = 1.1GB-1.4GB

So I would say that DA2 isn't very different from other games.
Maybe its just you, never really noticed other games.

You are under the impression that game engine uses GPU memory directly.
This it does not.
The only thing that have access to the GPU memory are the drivers, and NOT the game itself.
The more textures and polygons and AA the game uses, the more memory the GPU will use.
That's pretty much it.
The game has absolutely NOTHING to do with gpu usage directly.
A game can not "memory leak" gpu memory.

The game has a direct access to system memory only.

With the latest beta drivers, the game works flawlessly.
