Allocated and deducted gpu vram

I watched the video above recently and I am prompted to seek more clarification from fellows who know better here.

The video clearly shows that the vram memory size readout in msi afterburner is not what is actually used in-game.

I tried this in my msi afterburner settings and my dedicated vram was not getting to half my vram size in vr. Low res 0+ and 6g vram gpu.

 

I hear gpus with 10g and bigger vram filling up in vr and I am like, what really is enough size for vram?

 

Could this vram usage debunk video really have any relevance in explaining allocated and actual used vram?

I think that these types of videos, while informative actually improve our understanding of the various tech and how it works behind the scenes only marginally. The answer is, as it invariably always is with these types of questions:

 

It depends. And a lot of it depends on what software\games you run and how you run it on your GFX card. 

 

We have no idea how DCS World allocates VRAM and how much of the memory is pre-allocated, changed on the fly, emptied and filled up etc. What we can definitively say is that with increased resolutions, more VRAM is definitely better. In VR, not only are you pushing double the pixels of a typical scene, you are rendering two different viewpoints and here VRAM is definitely going to be an important consideration but definitively not the only one. 

 

In short. No it's not just about VRAM, it's the whole package. If you are asking whether your GTX1060 is enough to run DCS World in VR then I would say, yes you probably could run it at Rift S resolutions (and no upscaling) but only barely. It would not be a satisfying experience.

I didn’t know msi/af had a vram section. 
I usually see 13-15 vram usage in DCS. This is why I opted for a 3090 for running VR/G2 it’s an absolute must imho.

It is not an absolute must.

 

Telling people to spend upwards of $2000 on a GPU because DCS demands it is ridiculous.

 

It will run fine on a 3080 with 10GB of VRAM on a G2. And I would know.

As an owner of a G2, EVGA 3080 FTW3, and a 8600K, I would tend to agree with this.  However, everything is subjective.  I'm OK with 45 fps, medium settings and ghosting.  Not sure if the ghosting has a lot to do with VRAM or not, but that is the most difficult part for me.

 

VR is not for the faint of heart IMHPO.  It does require a lot of tweaking and some sacrifices.

 

Would I spend ~$2000 USD to increase my VRAM to try and reduce this.  No, not worth it in my opinion.  I started VR with an Oculus Rift CV1, GTX 1080, i72600K and have been VRing since.

Yes, it is quite a complex issue how dcs works in background.
My gtx 1060 6g is been doing just fine with Samsung odyssey plus for more than two years now on a medium to low settings.
An upgrade is needed now and the 3060ti is in my radar as an upgrade.

i run dcs in 4k resolution with high settings.

 

my 3080 rig runs fine with above 70 fps on average, not accurately measured.

 

i have problem running the same settings on my other rig that has a 3070, it's almost only half the fps comparing to 3080.

 

i tried different settings in dcs trying to lower the system memory usage and the video memory usage, from 18GB and 9GB to whatever i can get a better fps.

 

but it didn't work that way, dcs seems to be don't bother with the memory usage by changing the settings, at all.

 

now i'm considering buying another 3080 for a smooth 4k high dcs experience.

Sorry to dodge your FoxTwo but I wasn’t telling people to spend $$$ on a 3090. I said I opted for a system with a 3090 because I demand it not DCS. I’m sure the 3080 and G2 combo works well.
