nvidia ***Very Fast Intro to Shareable Vram (Nvidia)*** (VFISVN)

[Muchochostatia]

Very fast guide to increase your "virtual graphic card memory"

I didn't found any topic about it, so i created one. 

I'm very sorry for the Finnish text in pictures.

(Disclamer! Your mileage may very!)

 

Specs used in this test: 

2TB harddrive+Toshiba 120GB OCZ TL150+Samsung 850 240Gb and 

MSI GeForce GTX 960 Gaming OC (2GB)

Ok let's get started!

 

• 1.Firstly, press windows key on your keyboard, then click on the "File" icon

 

• 2. Next, go to top corner of the page and click "computer", and then to "properties"

 

 

• 3.Go to Administrator settings and then "properties" after that :settings (the middle one)

 

• 4. Ok, two final steps! Tick off the option in the left upper corner. After that one may choose where the extra virtual memory is simulated from. Then oneself can configure how much memory oneself may use! After all press "OK"

 

• 5. Restart you pc, to see effect. 

 

 =Profit!

If any problem just ask me!

not to be mean but do you say anything helpful?  

[samcool55]

Umm, i don't see how this can be useful?

As soon as a graphics card runs out of Vram and starts swapping the fps goes to single digits and becomes useless.

There are better options on the way like the AMD SSG. https://www.amd.com/Documents/Radeon-Pro-SSG-Technical-Brief.pdf

Isnt this just increasing page file size?

[ARikozuM]

This is only for page files. This doesn't do what you think it does. 

[SpaceGhostC2C]

Changing the size of the page file won't help you at all unless you are getting an "insufficient virtual memory" error message.

i was confused why you'd go into windows settings stuff to change the amount of system ram nvidia taps into

 

also, isnt overflowing into system ram pretty much automagicly allocated?

For no reason.

It is, but setting it to an NVMe or SSD is preferred for latency reasons.

It is, although Windows isn't always too smart about it: I've seen computers run out of virtual memory in full auto with plenty disk space, or even with manual min and max values, even though the allocated page file was way below the max value 

Not a problem the average user will face, though.

i was talking about VRAM overflowing into system ram.

[Windows7ge]

To my knowledge this has little to nothing to do with Video RAM. It has to do with Motherboard RAM. Some old style applications utilize virtual memory a type of swamp memory that is store on the hard disk (Or SSD by today's standards). I don't know why these old applications ever used such a thing but they did. More modern applications use mostly or solely physical memory which made/makes virtual memory obsolete but some applications can still use it.

 

I have completely disabled my paging files. I don't want applications using much slower swamp files if they don't need to and none of my applications have malfunctioned because of it.

 

To sumarize. Paging files do little to nothing to improve gaming. They are sometimes used when a system doesn't have enough physical RAM for its tasks. However with the huge advances in RAM density paging files are no longer a necessity why it's still even an option I have no idea.

Oh, that's even one step before virtual memory

Actually, it isn't application-dependent, but OS-dependent. And every OS I know of uses it.

You may do that, and most of the times you won't notice a big difference in everyday usage with large RAM quantities. But when using memory-intensive applications, you may hit a Windows error message despite physical memory being at less than 100%...

With the way Windows manages memory, i wouldn't call it exactly "an option". You can get away with not having it; whether it translates into any performance gain is to be seen...

So it's the OS itself which wants to utilize it. I'm wondering why the programmers decided to do such a thing. I've been told it was a method of keeping the system from freezing or crashing when physical memory is low but nowadays it just seems to use up unnecessary space on your boot drive.

Jeeze, I have 64GB of RAM in my workstation I'd hate for windows to tell me I don't have enough RAM when it's not even using all of it. What I really don't like about Paging Files is that on a Default installation the OS matches physical RAM at a 1:1 ratio. Meaning for every MB of physical RAM the OS is going to create a virtual block of usable memory equal to that. So me having 65,536MB of RAM. That takes quite a chunk out of my usable disk space. Even worse so on my dual xeon server with 128GB.

A long time ago running a mechanical 5400RPM HDD, Windows 7 x64, 8GB physical RAM, and a AMD phenom II B55 quad core processor I can say it did give my OS a noticeable kick in how long it took applications to load. To be honest I can't say it makes a noticeable difference with the hardware I have now but I can't have it using 65.5GB of my SSD. Same goes for the server except 128GB(131,072MB).

It only seems to do so for games that cycle through areas (cells) like MMORPGS, adventure, or open-world games. Most games will just ask the disk for the data that is needed.

i've actually never ran into a case where overflowing would make any damn sense either way.

 

as i used to say it when the whole 3.5GB mess was a thing: "the core craps out first anways."

I used to tel people the core crapped out before it could make use of more that 3.5 but no one believed me lol

i've tested it with a ton of actually sensible scenarios, and its usually the same group of people that yammer that 30fps is unplayable, that use a scenario where the core barely manages 30fps to show that it's not enough
