Can a GPU use DDR4 as VRAM if needed?

Hey guys, if a GPU doesn’t have enough VRAM for a game to perform optimally but there is plenty of available DDR4 system RAM is it possible for the GPU to use the system RAM as VRAM as needed to play the game optimally?

If you run out of VRAM, the game will not play optimally. So no, RAM is not a replacement of VRAM or is able to act as an equivalent emergency reserve.

yes

if it was useful give it a like :) btw if your into linux pay a visit here  and i will be thankful if you send me an opinion here

Well that sucks 😔. My GPU only has 11GB of VRAM so I need 1-2GB more to play my game at 1440p with max settings.

Too bad I guess, lucky for you, the 3090 does exist.

I wonder how it is playing at 1440p

 

Yes, its a 2080 Ti. It plays fine.

can it use system RAM? absolutely yes

should it use system RAM for GAMES? no, turn down settings

Things I need help with:

Spoiler

none atm

 

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

 

Spoiler

 

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

 

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

 

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

 

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

 

Personal Blacklisted Companies:

Spoiler

Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)

 

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

you could try playing it at those settings, it may or may not use the VRAM, depending on scene

if it does stutter or have any issues, then turn down settings

I have zero problems with VRAM with my 2080ti at 1440p/144hz.. what games you using that are maxing out your VRAM and making you use system memory?

Some games or tasks reserve vram which is then reported as in use, but not actually used. If you run out of vram, you will notice. 
 

I run 1440p ultrawide on 6gb and it’s fine so I guess you should be good.

Lower the texture quality,high and medium still look good in modern games and free up a lot of VRAM.

just use it and see if you get any issues... I still don't believe the game will actually use that much VRAM

I just bought it and its downloading now. I have a 2080ti as well and I have a 1440p/144hz monitor. Ill let you know what I see when I get done and load it up briefly. But as @WereCat said, just because its saying that, it most likely wont actually use that. You can watch it in MSI Afterburner or GPUZ or HWinfo64 and see how much VRAM its actually using, I doubt it will use over 8gb actual VRAM.

I doubt that game actually needs 13GB of VRAM to run at 1440 w/ Max Settings.

unfortunately I'm not aware of any SW that can display actual VRAM usage instead of allocation. MSI Afterburner, GPUZ, etc... all only show allocation. 

 

For example CoD Warzone will allocate all the VRAM even if it can't use it all.

I’ll try that and see. I didn’t know I could monitor VRAM usage. I thought I could only view RAM usage like in task manager.

 

Also if you increase the image scaling the VRAM shoots through the roof up to a whopping 14GB!

This is quite strange.

 

To what I know, when your GPU used up all its memory, it begin to used shared memory (which is system RAM). This will be done automatically and you don't really have control over it as Windows will allocate the shared RAM.

I just played the first few minutes with everything maxed and HDR enabled since I have an HDR monitor, the graphic setting said 12.69gb needed, but I only ever saw 6-9gb used according to GPUz.

Hmm I wonder why they would say it requires almost double what it actually does. 🤔 

 

You would think the devs would’ve wanted players to enjoy the best experience possible graphically and people probably have settings turned down below necessary due to what the game says is required.
