VRAM question

[don_svetlio]

GPU-Z gives me 2 readings - Dedicated and Dynamic - are both part of the VRAM or is there a special reason for them to be 2 - asking since VSR Witcher 3 maxed resulted in 2.442MB of Dedicated + 312MB of dynamic being used.

I read somewhere that dynamic is system memory, used for swapping when the VRAM gets full or some VRAM information is not needed yet, not sure if that's true.

Hmm - why would it activate when I am at 2.5GB of usage? Odd.

Dedicated is the vRAM on the graphics card itself. Dynamic is the shared system memory.

Think of it this way, Windows doesn't need fast vRAM for its GUI, while games do.

Still - if 2.5GB of usage didn't result in anything weird happening I'm almost sure the VRAM on the card is fine and if OCCT doesn't pick up errors the core should be fine. Right?

I'm fairly certain that dedicated is the actual VRAM while dynamic is the shared system memory(regular RAM). All graphics cards allocate some system memory as an "overflow", because if they didn't games would either crash or not display textures properly if they ran out of VRAM.

Its probably using it as cache, since not everything can or should be loaded in the frame buffer(by having unused textures in the frame buffer, it can kill the FPS and other texture loading speed).

I see. Thanks

That's odd. Can you manage a full 3GB forced in a game without VSR? I'm pretty sure VSR needs you to be fullscreen like DSR does, so without a second monitor windows shouldn't be rendering anything (if you left GPU-Z in logging mode).

 

Though you had an answer I'd like to get an idea about this. What's your OS as well?

Windows 8.1 - VSR to push as much VRAM usage as possible to stress test it - managed to get to 2.440GB with 300MB Dynamic. I used Witcher 3 as a test game - the most taxing one I own

I also stress tested with OCCT for the core

Can you try Gametime on Origin for Titanfall? Insane textures WILL eat up 3GB or more of vRAM. It'll be a good way to check if your card can sufficiently use all 3GB. I've never seen a card default to dynamic vRAM without having a real need to, but then I don't really have the sensors for it.

I can't

Don't have those.

You shouldn't need to own the game. You can get it free for 48 hours on Origin using Origin Gametime. Of course, it'd require you to download about 50GB though.

 

GTA V could do it as well. So could Dying Light. BF4 using 200% resolution scale and 4x MSAA could too, though it'd be unplayable framerate-wise for you.

No idea - but I did what I wanted - stress tested the VRAM - it's allocated randomly so I should have tested all of it with the 2 subsequent runs of Valley 2540x1600 Extreme that used 2GB. And since OCCT didn't find artifacts and the VRAM is fine the only thing left for me to blame for the random lines that flashed on LTT is firefox. BUGZILA FIREFOX!

TitanFall Tutorials - this is about 30 minutes of them.

So I guess that means the VRAM is fine - I didn't notice any artifacting or whatever.

Yup! Looks good to me =D.

Though admittedly the game is hectic as fuck - during an intense firefight it's hard to be looking for those .

Gotta get with da playclaw overlay bruh. See it ALL in real time =D.

 

And yes, it's hectic. I loved it though. I went flawless so often because I had time to react to being shot.

Yep - not my cup of tea. I'm more of a CS:GO-style FPS player - where positioning, grenades, noise, reaction timing are important - where you die for not paying attention - realistic you might call it .

I'm just bored in fps games where I'm a bullet sponge. Hence why I play shooters on maxed difficulty - Metro Last Light once on Sparta Hard and once on Ranger harder - the ranger playthrough was fucking awesome. Beating a boss with my last clip - I barely survived and was proud as fuck - or beating a boss right as the air on my filter runs out so I gotta run to the door else I die. Had to fix my timing several times before I beat him fast enough.

Out of curiosity, is there a way to configure or disable shared VRAM? Since Windows decides that taking 3 of my 8GB to a 7950 will totally do an improvement.

Bios setting to set memory to the iGPU - that's as far as it goes IIRC.

 There aren't any user selectable options that I know of(in either CCC or NCP), there could be a 3rd party tool that gives you the option but I've never searched for one, and you can for sure do it with registry hack(anything is possible at this point). Luckily the shared RAM isn't like dedicating RAM to an iGPU, so you can still use the 3GB with programs(assuming it isn't already being used, and vice versa).

Do you only have access to 5GB of RAM? If your PC says you have access to all 8GB then you're just fine.
