How much VRAM do you actually need?

The short version, for a new card bought today and expected to last:

“Workable” means you will meet games where you turn textures down a step. “Will hurt” means stutter in recent titles at settings the card is otherwise fast enough for.

That table is the answer. The rest of this is why, because video memory is the spec most often misread — usually in the direction of panic.

What it is actually holding

Video memory stores what the card needs immediate access to while drawing: textures, geometry, shadow maps, the frame buffers themselves, and whatever the engine is caching. Textures dominate, which is why texture quality is the setting that moves the figure most.

The critical property is that it is not a gradient. Running slightly short of processing power gives you slightly fewer frames. Running short of video memory gives you something qualitatively different: the driver starts moving data across the PCIe bus to system memory, which is an order of magnitude slower than the memory on the card. The symptom is not a lower average — it is frame time spikes, textures loading in late, and a sudden hitch when you turn a corner into new scenery.

This matters for how you diagnose it. Average frame rate can look fine while the experience is bad. Look at 1% low figures, or just notice whether the game stutters when the scene changes.

Your monitoring overlay is overstating it

This is the most important thing in this guide, and it causes a great deal of unnecessary worry.

MSI Afterburner, the driver overlays and most other tools report allocated memory, not memory in use. Games routinely reserve far more than they need, because unused video memory is wasted video memory — if it is there, an engine may as well cache into it.

The consequence: the same game, same scene, same settings will report perhaps 7 GB on an 8 GB card and 13 GB on a 24 GB card, while performing identically. The 24 GB figure is not evidence that the game needs 13 GB. It is evidence that it was offered 24 and helped itself.

So “my game is using 11 GB” tells you almost nothing about whether 12 GB is enough. The useful test is behavioural: does it stutter when the scene changes, and do textures pop in late? If not, you have enough, whatever the number says.

What actually drives the requirement

Resolution, less than you would expect. The frame buffers scale with pixel count, but they are a modest share of the total. Going 1080p to 4K is four times the pixels and roughly 1.5 times the video memory, not four times. Textures are stored at the same resolution regardless of your display.

Texture quality, more than anything else. This is the dominant term by a wide margin, and it is also the cheapest to turn down visually — at normal viewing distance one step below maximum is genuinely hard to identify.

Ray tracing. Adds meaningfully, because the acceleration structures have to live somewhere.

Frame generation. Also adds, which is worth knowing: it is often suggested as the fix for poor performance on a weaker card, and on a card already short of memory it can make things worse rather than better.

Texture packs and mods. A high-resolution texture mod can double the requirement on its own.

Is 8 GB finished?

No, and the discourse overstates this.

At 1080p, 8 GB is still workable in most current games. You will meet titles where textures go from Ultra to High, and the visual cost of that is small. What has changed is that 8 GB is no longer comfortable — it was ample in 2020 and it is now the floor.

The honest framing: 8 GB is a poor amount to buy in 2026 for a card you want to keep for several years, and a perfectly reasonable amount to own at 1080p right now. Those are different questions and they get conflated constantly.

Where 8 GB genuinely struggles is a specific and increasingly common combination: 1440p, ray tracing, high textures, in a recent AAA release. If that is what you play, it is a real constraint today rather than a future one.

Does more make the card faster?

No. A 16 GB version of a chip is not faster than the 8 GB version when neither runs out — same processor, same clocks, same memory bandwidth in most cases. The extra capacity prevents a cliff; it does not raise the ceiling.

This is why “more VRAM” is poor reasoning for choosing between two different cards. A faster card with less memory will beat a slower card with more in nearly every game that fits in both. Capacity only wins when the smaller card runs out.

The place extra memory earns its price is longevity. Requirements rise over a card’s life, and the one with more headroom stays comfortable longer. That is a real argument — it is just an argument about three years from now, not about today’s frame rate.

If you are short right now

In order of how much they recover per unit of visual sacrifice:

1. Texture quality down one step. Almost always enough, and the least noticeable change you can make.
2. Turn off ray tracing, or reduce it to the lowest setting that still enables it.
3. Turn off frame generation if you have it on.
4. Shadow resolution down — a meaningful allocation, modest visual cost.
5. Drop resolution scaling before dropping output resolution. Using DLSS, FSL or XeSS at Quality renders fewer pixels internally and reduces the buffer cost while keeping the output sharp.

Note what is not on that list: anti-aliasing and most post-processing effects cost processing rather than memory, so turning them down will not help with this particular problem.

Checking your own card

Our VRAM checker will tell you which of the games we model fit in a given capacity at your resolution and preset, and what falls short. Like everything else here, those requirements are modelled from published figures rather than measured, so treat them as a guide to the shape of the problem rather than an exact threshold. Every graphics card page carries the same verdict for that specific card.

And if you are deciding between two cards, the question to answer first is which is faster. Memory only decides it when the faster card would run out — which, at 1080p today, is rarer than the internet suggests.
