Can you tell us what operating system you are interested in monitoring the usage from? Also, knowing what make/model of video adapter may be useful as well. :) –  Ƭᴇcʜιᴇ007 Jul 5 '10 at 20:43
    
I'm using windows 7, mainly. –  stacker Jul 6 '10 at 1:02

You can check it via the dxdiag utility. –  happy_soil Jul 6 '10 at 8:49

The GPU is graphics card specific so there won't be a general tool that monitors this. Look for something specific to your graphics card. –  ChrisF Feb 27 '11 at 14:22

MSI Afterburner (a tool similar to RivaTuner) can show this in real-time on a graph, among other things. Note that it does not require a MSI card.

AMD System Monitor is pretty good. It gives you % CPU and GPU utilization.

If you use an ATI or NVIDIA card, you should check out GPU-Z.

Main Features:

  • Support NVIDIA and ATI cards
  • Displays adapter, GPU and display information
  • Displays overclock, default clocks and 3D clocks (if available)
  • Validation of results
  • No installation required
  • Support for Windows 2000 / XP / Vista / Windows 7 (both 32 and 64 bit versions are supported)

You almost got -1 for using ATI –  bobobobo Aug 26 '12 at 22:38

You can monitor NVidia GPUs with RivaTuner

GPU load monitoring is not a built-in feature in Windows, but there are third-party tools to do the job.

GPU-Z is a graphics card information tool that supports a number of monitoring options for graphics cards such as clock speeds, fan speed, memory load, GPU load and Video Engine load.

I believe it supports both ATI (AMD) and nVidia graphics cards.

For my model it only shows the Clocks, not the load –  Jader Dias Feb 27 '11 at 19:55
