Open Task Manager with Ctrl + Shift + Esc, select Performance, then choose the GPU you want to check. Its Dedicated GPU memory total is the key figure for a discrete graphics card. Shared GPU memory is system RAM, not extra physical VRAM.
Check VRAM in Task Manager
- Press Ctrl + Shift + Esc to open Task Manager. If it opens in compact view, select More details.
- Choose Performance and select a GPU entry, such as GPU 0 or GPU 1.
- Check the GPU name and the total shown for Dedicated GPU memory or Dedicated GPU memory usage. The graph may show both current use and capacity; use its total capacity, not the amount currently in use.
- If your PC lists more than one GPU, select each entry and note its name and dedicated-memory total. Use the value for the adapter assigned to the game or application you care about.
Task Manager is the quickest built-in check for most Windows 10 and 11 PCs. Microsoft explains the distinction between dedicated and shared memory in its Task Manager GPU overview. If Task Manager is missing a GPU or shows an unexpected value, verify it with dxdiag.

Verify the amount with DirectX Diagnostic Tool
- Press Windows + R, type
dxdiag, and press Enter. - If Windows asks whether to check that drivers are digitally signed, select Yes.
- Inspect the Display tabs, such as Display 1 and Display 2, and any Render tabs available.
- Record the adapter name and look for Dedicated Display Memory, Display Memory, or a similarly named memory field. Treat shared and total-available values separately.
Tab names and memory labels vary by Windows version, driver, and graphics configuration. On a laptop with integrated and discrete graphics, check every relevant tab rather than assuming the first one represents the high-performance GPU. dxdiag is also useful for inspecting display-driver information; Microsoft documents the separate graphics-memory categories in its graphics memory reference.
Use Display Adapter Properties
- Open Settings > System > Display > Advanced display.
- Choose Display adapter properties for Display 1, or the corresponding option for the display you want to inspect.
- On the Adapter tab, note Dedicated Video Memory, Shared System Memory, and Total Available Graphics Memory, if shown.
This legacy properties view can be a useful graphical fallback, but the selected display may be connected through an integrated GPU even when the PC also has a separate NVIDIA or AMD adapter. The path and labels can differ between Windows 10 and 11. Microsoft’s graphics-memory reporting examples show why these categories should not be treated as interchangeable.

Dedicated memory, shared memory, and total available memory
Windows uses “GPU memory” as an umbrella term. Dedicated memory on a discrete GPU generally corresponds to memory physically installed on the graphics card. An integrated GPU may instead use system RAM, sometimes with a small amount reserved for graphics. Windows manages graphics memory through its video memory management system; Microsoft describes that model in its video memory management documentation.
| Windows label | What it means | Count as physical VRAM? |
|---|---|---|
| Dedicated GPU memory / Dedicated Display Memory | Memory reserved for or physically attached to the GPU. For a discrete GPU, this generally reflects its VRAM capacity. | Generally yes for a discrete GPU; interpret carefully for integrated graphics. |
| Shared GPU memory / Shared System Memory | System RAM that Windows can make available to the GPU. | No. |
| Total Available Graphics Memory | A Windows-reported total that can combine dedicated and shared memory. | No. It is not the card’s VRAM capacity. |
| GPU memory usage | Memory currently used or allocated, rather than the adapter’s total capacity. | No. It is a live-use figure. |
For example, Microsoft documents a reporting example with 8,192 MB of dedicated memory and 24,532 MB of shared system memory, for 32,724 MB total available graphics memory. The accurate description is 8,192 MB dedicated—not 32,724 MB of VRAM. A separate Microsoft example shows 128 MB dedicated plus 16,296 MB shared, totaling 16,424 MB. These are Windows reporting examples, not specifications for a particular retail GPU.

Check with PowerShell (for inventory or scripts)
PowerShell can list adapter names and the WMI-reported memory value:
Get-CimInstance Win32_VideoController | Select-Object Name, AdapterRAMTo convert the reported bytes into gigabytes:
Get-CimInstance Win32_VideoController |
Select-Object Name,
@{Name='AdapterRAM_GB'; Expression={
if ($_.AdapterRAM) {
[math]::Round($_.AdapterRAM / 1GB, 2)
} else {
$null
}
}}Microsoft documents AdapterRAM as a byte-valued property of Win32_VideoController, but warns that the class can return inaccurate values for hardware that is not compatible with WDDM. The property is also 32-bit, so it is not dependable for identifying modern GPUs with more than 4 GB of memory. Use Task Manager or dxdiag to verify a modern card’s dedicated VRAM. See Microsoft’s Win32_VideoController documentation.

Which GPU should you check on a laptop?
A laptop may list an integrated Intel or AMD GPU and a discrete NVIDIA or AMD GPU. GPU 0 is not always the faster adapter, and the display itself may be routed through the integrated GPU even when a discrete GPU renders a game or application.
- Compare the GPU names in Task Manager and
dxdiag. - Inspect every GPU entry and display-related tab.
- For a specific workload, identify the adapter assigned to that application rather than choosing an adapter by its list number.
If the reported VRAM looks wrong
Dedicated memory is 0 MB or unusually small
This can be normal for an integrated GPU that relies on shared system memory, or it may mean you are looking at the integrated adapter instead of the discrete one. It can also happen when a driver exposes no dedicated-memory counter. Microsoft notes that some GPUs do not use dedicated GPU memory and may show zero or no counter in the affected reporting scenario.

The GPU is missing or its details are incomplete
A generic, outdated, or malfunctioning display driver can limit what Windows reports. Check the adapter name in Task Manager, Device Manager, and dxdiag. Install the appropriate graphics driver from the PC maker or GPU maker, restart Windows, then check again. For a laptop, start with the laptop manufacturer’s driver guidance.

Small differences do not automatically indicate faulty hardware. Windows and drivers may reserve some memory, use different reporting categories, or display rounded values; manufacturers may also advertise memory using decimal units while Windows uses binary-derived values. Virtual machines and remote sessions may expose only an assigned portion of a physical GPU. Compare the adapter model and dedicated-memory reading across Task Manager, dxdiag, and the manufacturer’s specification.

A process reading does not match the GPU total
Per-process GPU memory is not the right figure for identifying an adapter’s total VRAM. In certain Windows configurations, per-process dedicated GPU memory counters can report incorrect values even when the Task Manager Performance pane shows the expected value. For that documented issue, use the Performance pane for the dedicated-memory reading; see Microsoft’s GPU process memory counters guidance, updated February 12, 2026.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Check VRAM usage, not just VRAM size
To see current activity, open Task Manager > Performance > GPU and inspect the memory graphs. For application-level readings, Task Manager’s process view can show GPU memory columns, but treat them as usage indicators rather than a definitive measure of physical VRAM consumption. A game’s graphics settings or a GPU vendor’s monitoring tool may report allocation or use differently.
Can you increase dedicated VRAM?
You cannot normally increase the physical VRAM capacity of a discrete graphics card through Windows settings. Some integrated-graphics systems offer a firmware setting for pre-allocated graphics memory, but that does not create more physical memory and can reduce the RAM available to Windows; whether the option exists depends on the hardware and firmware.
