That can force lower texture settings and contribute to texture pop-in or stutter. But adding VRAM does not automatically raise average frame rates: when the workload fits, GPU processing power and the rest of the memory system can matter more.
What VRAM does—and what capacity does not tell you
Video RAM (VRAM) is the graphics card’s on-board workspace for data used to render a game, including textures and other graphics assets. Its capacity determines how much data can reside there. Memory bandwidth and the broader memory subsystem affect how quickly the GPU can move data, while the GPU’s compute resources determine how quickly it processes rendering work.

Those are related but distinct characteristics. A card with more VRAM may have more room for demanding assets, but capacity by itself does not describe processing speed, bandwidth, architecture, cache, or overall gaming performance. NVIDIA cautions that memory bus width alone is not enough to judge a card’s memory subsystem in its RTX 4060 Ti 8GB versus 16GB explanation. AMD likewise treats video memory as one consideration alongside compute capability, performance per dollar, and upscaling in its Radeon graphics-card lineup.

More capacity is most useful when the game’s actual workload exceeds the smaller card’s effective capacity at the resolution and settings you selected. In that situation, the game may need to reduce asset quality or move data in and out of memory, potentially causing texture pop-in or less consistent frame delivery. AMD says ample VRAM can help reduce texture pop-in and leave more room to raise settings in its Radeon VRAM guidance.

If the workload fits comfortably, extra capacity alone may have little effect on frame rate. NVIDIA’s model-specific explanation says the 8GB and 16GB versions of the RTX 4060 Ti can play at maximum settings with the same performance in most games, while noting some titles where an 8GB card may require High rather than Ultra settings. That is a manufacturer’s statement about those models and games, not a rule that predicts every GPU comparison.
What raises a game’s VRAM demand?
Resolution and rendering workload
Higher resolutions require the GPU to process more pixels, which generally raises rendering workload. CD PROJEKT RED’s example compares 5120 × 2880, or 14,745,600 pixels, with 2560 × 1440, or 3,686,400 pixels—about four times the pixel count. That is a pixel-count comparison, not evidence that the higher resolution needs four times as much VRAM or runs at one-quarter the frame rate. The game’s performance also depends on other hardware and software factors. See CD PROJEKT RED’s resolution and performance guidance.

Textures and optional assets
High-resolution textures and optional texture packs can increase memory demand. Their effect depends on the title and the selected settings; a game’s Ultra texture option is not a universal measure of how much memory every game needs.
Ray tracing and other graphics options
Ray tracing and other visual features change a game’s resource demands. Benchmark results are meaningful only when the settings are clear. For example, AMD’s comparison of a Radeon RX 6750 XT 12GB and GeForce RTX 4060 Ti 8GB used Far Cry 6 at 1440p Ultra with ray tracing set to High, on a Ryzen 9 7950X3D system, in a test dated May 16, 2023. Because the cards are different GPU models, that comparison does not isolate VRAM capacity as the cause of any performance difference. The configuration is described in AMD’s VRAM guidance.

The game’s own memory behavior
Games may allocate or reserve more VRAM when it is available. As NVIDIA explains in its RTX 4060 Ti memory comparison, an overlay’s “used” or allocated figure does not prove that all of that memory is actively required; determining precise active use can require developer tools. Treat the number as a clue, not a diagnosis.
What benchmarks can—and cannot—show
Results vary with the game, graphics settings, test scene, and GPU model. PC Gamer’s 2026 test suite compared RTX 5060 Ti 8GB and 16GB cards and RX 9060 XT 8GB and 16GB cards. In Kingdom Come: Deliverance 2 at High settings, its reported average VRAM use was below 8GB for all four cards, and the 8GB cards performed well; the performance gaps were tighter than in its Ultra-settings tests. In some other tests, including specific Cyberpunk 2077 settings, the 16GB versions sometimes delivered higher average frame rates or stronger 1% lows.

For one specific Kingdom Come: Deliverance 2 test at 1080p High with Quality upscaling, PC Gamer reported 171 average FPS and a 152 FPS 1% low for the RTX 5060 Ti 16GB, compared with 153 average FPS and a 126 FPS 1% low for the RTX 5060 Ti 8GB. Those figures describe that outlet’s test conditions, not a guaranteed gain from adding 8GB to any graphics card. Even comparisons between versions of the same card should be read in the context of the exact test, while comparisons between different GPU models cannot attribute a result to capacity alone. See PC Gamer’s 2026 VRAM testing.
The available comparisons do not establish a universal number of frames per second gained per additional gigabyte. To choose between cards, compare the models in the games and settings you actually use rather than relying on VRAM capacity as a proxy for speed.

How much VRAM do you need for gaming?
There is no universal capacity minimum that guarantees a particular resolution, frame rate, or settings level. Requirements vary by game, texture quality, features such as ray tracing, and the performance you expect. ASUS offers broad buying guidance of 8GB for 1080p, 12GB for 1440p, and 16GB for 4K, but these are the manufacturer’s recommendations—not requirements that apply to every game or card. ASUS also says average FPS is primarily set by GPU core performance. Check the guidance against tests for the games and settings you care about: ASUS graphics-card guidance.
- Start with your games and settings. Find benchmarks at your target resolution, texture level, and ray-tracing settings.
- Compare average FPS and 1% lows. Similar averages can hide less consistent frame delivery or more pronounced dips.
- Assess the whole GPU. Consider compute performance, memory bandwidth, architecture, relevant cache, and capacity. Bus width alone is not a sufficient measure of memory-system performance.
- Consider capacity as headroom. More VRAM can accommodate larger assets or more demanding settings when capacity is the constraint, but it is not a frame-rate guarantee.
- Include price and features. Compare the card’s cost and relevant features, such as upscaling support, alongside its performance in your games.
How to check whether VRAM may be causing a problem
If a game stutters or textures pop in, check whether the issue changes when you reduce memory-intensive settings. Use the same repeatable scene so you are comparing like with like.
- Lower texture quality. Replay the scene and note whether pop-in or stutter changes.
- Reduce resolution or texture size, or disable especially demanding options. ASUS recommends reducing resolution or texture size to lower memory demand in its graphics-card guidance.
- Compare frame delivery as well as visuals. Note average performance and whether dips or stutters improve; do not rely on a single memory-allocation reading.
If reducing these settings improves the problem, memory pressure may be involved, but that observation alone does not prove VRAM capacity is the cause. Game behavior, GPU performance, and other system factors can also affect the result.
