How much VRAM do various games use in Ultra?

[Elliot B.]

Since the performance of the GTX 970 has been shown to plummet when you use between 3.5 and 4 GB of its VRAM, I want to make sure I wouldn't hit this amount in my games before I choose to purchase the card.

 

How much VRAM do various games use in Ultra at 1920x1080?

 

I'm thinking games like Battlefield 4, Grand Theft Auto IV, Far Cry 4 etc.

You should be able to find software that measures Vram currently in use, I believe GPUz does it.

Not if you don't have the VRAM to start with.

 

e.g. If you have a card with 2 GB VRAM and max out a game that could use more than 2 GB VRAM, software such as GPUz would only show 2 GB as being used.

Found this...

 

 

Sounds like games are already using over 3.5 GB VRAM at 1440p, even at 1080p.

 

I think I will get a card with 4 GB full-speed VRAM

Ah that makes sense.  I didn't realize BF was such a hog when it came to Vram.

[Torolol]

so BField4 actually performs better at 2160p than 1080p for GTX970?

BF4 doesn't make sense to me.

Unused RAM is wasted RAM so might as well us it completely if possible.

I am curious, what happens if your graphics settings require more VRAM than you have available?  Will it just be a performance hit?  Does it swap like system memory?

Hi, I found one program that might will help you with Gpu usage.
