Look at this VRAM usage!

[nigelmcelwee]

Check out this quick snapshot I did on a create fast mission. Granted I run a lot of high settings and have a 12GB GFX card but look at how much of the VRAM is being used!! Over 7GB of VRAM.

I feel like this game is the new crysis 3

 

 

 

Jokes aside:

I have a 2gb GPU and with the preload and tree render distance sliders down it will do about fine, but RAM usage is still a bit broken. (VRAM and System RAM)

[nigelmcelwee]

yeah I mean because I have a lot of overhead I am not feeling the pinch at all but there aren't many people out there with a 12GB vram card at the moment.

[VAF [136] Striker]

Yeah, that's a hefty drain.

[nigelmcelwee]

on the plus side, the latest patch has brought my performance back!

[dburne]

It is just making good use of that nice video card you have !

 

Unused vram is wasted vram right lol.

I haven't seen VRAM that high on my card, and my card has 8Gigs

[kontiuka]

I just have a 2 gig card so why does my VRAM usage say over 3000 MB?

[BitMaster]

mine varies between 3501MB ( seems to be the entry point in my case ) and something above my actual 4GB...

 

it's nice to see DCS and DX11 making use of what is there :)

as I understand it when the VRAM is maxed out your system will use system ram as well.

Could it be that the game reports not in MB, but Mb?

[sFalcon]

I get more than 10000MB VRAM usage if i loadup 9 or more different planes/helis in the same game/server

 

My RAM usage also skyrocket this way, besides the nonstop slow growing ram usage caused by the memory leak

Highly doubtful. Only network guys like myself use Mbits! :)

MB = storage size, Mb = transfer rate

[sFalcon]

Gpu-z is showing much lower graphics memory usage

I read somewhere that just because x amount of VRAM is in use when playing a game, it doesn't mean that game is actually using or needs to use that much. Not sure what they meant, maybe it just doesn't efficiently clear out unused textures if there's free VRAM it can use but if DCS works fine with 2GB you have to ask what is using the extra 5GB on your card and is it actually making a real beneficial difference.

MB = storage size, Mb = transfer rate

 

Since most of us into sims are anal and very technical. :D

 

MB is just Megabytes. *Very often* people count 1,024 as a KByte. This is true when talking about memory and disks.

 

Mb is just Megabits. Almost always, it means a million bits.

 

So to sum up, most developers, disk, server folks will consider 1KB as 1,024 bytes. But universally, network folks will consider 1Kb as 1,000 bits.

 

Am I being pedantic, you betcha. But I live in a world where the difference between a "B" and "b" is *HUGE*.

I think the value is not calculated/shown correctly or there is another problem.

 

Do this:

* start instant action/fast mission with aircraft (let's say Hawk)

* get in cockpit, note VRAM usage

* return to main menu

* start again instant action/fast mission but with another aircraft (let's say C-101)

* get in cockpit, note VRAM usage

* return to main menu.. repeat

 

At first, I have something like 3.9GB usage (graphics card has only 3GB).

On second loading, I have around 8GB usage.

Third time, 9-10GB..

 

So either the value is not correctly shown/calculated or it leaks memory somewhere or loads same resources multiple times.

 

When there is a performance "hiccup" (stuttering) I notice VRAM usage change a bit so that might be about moving things from system RAM into VRAM? Would that be avoided if memory usage was not so high?

 

Edit: it is not about aircraft/module either, you can do same with TF-51 and P-51 as well with similar results.

 

Edit2: loading into A-10C I get 3068MB usage and things work fine. Returning to main menu and loading into A-10A I get 3735MB usage and I get stuttering and bad framerate..Back to main menu and into A-10C it is now 4278MB..

Yeah, I don't think DCS is reporting the correct vram usage at the moment.

 

I get 100 fps and supposedly 4GB of vram usage with only a 2gb card... Something seems off to me.

Either way, it seems to be leaking memory at some point and causing performance slowdown due to that..

 

Hard to figure out more without seeing actual code..

yeah , I cant imagine I'm using that much vram!

[dburne]

On average my vram usage on my 4gb GTX 970 is around 2.2-2.3 gb.

[Punisher74]

I was playing on multiplayer last night and my VRAM usage jumped from 4gigs to over 9gigs. There already has been a memory leak reported. So all I can say is hang in there. It should be fixed soon since the devs know about it.

[Dappman]

Crapped out shortly after 15,000. I have a 3GB card.

 

[tintifaxl]

I don't know what VRAM usage is reported within DCS, but MSI Afterburner never shows these numbers. On Caucasus with 1.5.2 VRAM usage is around 3 GB, on NTTR the highest I got was 4.5 GB.
