so Windows 10 can actually use system ram for vram?

Do you notice a significant FPS drop before and after it passes the 6GB mark? I'm just a little surprised your GPU is so taxed, but putting out a good framerate.
 
Doesn't that happen in all the previous OS's? I doubt it would use the HDD instead of the system ram in any OS.

No not at all. I think that is simply because its only allocating more but does not technically need it in this case.

I hope that's the case since none of Nvidia's offerings except the Titan X offer more than 6GB of RAM right now, and if I'm not mistaken SLI won't help you in that regard either.
 
Humm interesting glad i got the 16gb model of my laptop then. And the 4gb dGPU model at that...
 
? this has always happened, but only in extreme cases. what i want to know is how the fuck you're using almost 7 gb of vram at 1080p.

I said the screenshot was at 4k. At 1080, it uses about 5.5 GB.

And not once did I see this happen on Win 8.1 or 7. My 660 ti, 770, 780, 970, 980 and 980 Ti never went above the actual amount of vram they had in any game that I tested.
 
that shouldn't be really happening.. im under windows10 and it never happened to me with none of my cards being Red or Green side, a bug with afterburner maybe?... the large amount of RAM used (unless you have a lot of background things, chrome tabs etc, also point to a heavy pagefile usage. but that shouldn't be reflected in the total vRAM usage.

Not sure but I know darn well it did not happen before going to Win 10. I know for a fact that on Win 8.1 and 7 that it would max out ram usage at just a little bit less than what was actually there. For example if I had 2 GB card then it would not even even use all 2048 MB before being tapped out.

The large amount of ram is because I have lots of stuff open so nothing odd going on there.


EDIT: I cant think of many games that use a lot of vram but I tried Ryse and it will eat over 7200 MB at 4k with 2x2 SSAA. Lol of course its a slideshow as that is the same as running 8k.

Bug. It's not reaching across the PCIe bus into your freaking system ram. Even if it did it would stutter like crazy since it's infitessimaly slower. This phenomenon is ultimately meaningless and useless.

This is what Windows 7 shows for GPU ram, GPU + Shared,

What it probably does is offload graphics elements that are no longer in use and stores it in system memory so that if it needs to be called up again it can load it from the systems ram instead of the hard drive.
So it may show more ram in use than your card has, but it's most likely showing the shared ram in that number you are reading

Of course it would be slower if it actually NEEDED that ram as vram and I already addressed that. The only reason I started this thread is that I thought it was bizarre to be going over the amount of vram that I have and was not sure if this was a normal thing to happen in Win 10.
