I want to enable GPU rendering, but there is no option in User Preferences > System:

Why is this? How can I get cycles to render using my GPU?

I'm using OpenSUSE 13.1 x64 with Nvidia official repo drivers installed. However, despite I bought an nvidia Geforce 650GT, stil have no GPU option available on Blender. What am I missing or doing wrong? –  user3305984 May 15 at 13:42
    
@user3305984 Without more info it's hard to say. This site isn't really designed for back and forth discussions (as will undoubtedly be the result of troubleshooting etc.), so you'll probably have better luck on a forum like BlenderArtists –  gandalf3 May 29 at 19:19

Make sure your GPU is supported.
Cycles only supports Nvidia graphics cards at the moment. If you are using an AMD/ATI graphics card you are out of luck for now (though there are some promising tests using experimental drivers).

Cycles only supports GPUs with a CUDA compute ability of 2.0 or higher. Check to makes sure your GPU is on this list of CUDA capable GPUs and has a ranking of at least 2.0.

Make sure your drivers are up to date.
If your GPU has a CUDA compute ability greater than or equal to 2.0 and you still don't have the option to enable GPU rendering, you can check a couple more things:

Below are instructions for various operating systems. If you are still having issues even after updating your drivers, try asking for support on BlenderArtists.
Note that questions about OS/driver configuration (i.e. not about Blender) are off-topic here.

Linux

Debian based Linux Distributions (Ubuntu, Linux Mint)

  • Open your driver manager and select the recommended driver and Apply Changes.

  • You can also use the terminal to install the latest stable driver.

    sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
    sudo apt-get update
    sudo apt-get install nvidia-current
    

Arch Linux

Identifying your GPU:

From the Arch wiki:

If you don't know what GPU you have, you can find out by running:

lspci -k | grep -A 2 -i "VGA"

Drivers and CUDA:

For Arch Linux, installing proprietary Nvidia drivers for your GPU can be as simple as installing the nvidia package and then rebooting:

# pacman -S nvidia
# systemctl reboot

If you are compiling Blender from source, you will also need the CUDA toolkit. You can get it by installing the cuda package:

# pacman -S cuda

Note: Due to an issue with the latest nvidia drivers (version 334.21), you must run blender (or any other program which uses cuda) as root before you can use any cuda features as a normal user. See this thread on the archlinux forums for more detail.


Windows 7

  1. Find out what GPU you have in the Device Manager. Go to Start -> Control Panel -> System and Security -> System -> Device Manager), then open the Display adapters tree.

  2. To find out the architecture of your Windows installation, open a command prompt (search for cmd in the start menu) and run wmic os get osarchitecture.

    enter image description here

    Alternatively, you can get this information from a GUI by going to Start -> Control Panel -> System and Security -> System or by using the keyboard shortcut Windows KeyPause.

  3. Go to the Nvidia Website and select your driver.

  4. Finally, download and install the proper driver for your architecture. I am assuming you know how to use installers.

Nvidia Optimus:
If you're running Blender on a notebook with Nvidia Optimus, make sure it uses the dedicated GPU. Either configure Blender to always use the dedicated over the integrated GPU in the Nvidia Control Panel, or right-click Blender.exe (or a shortcut to Blender) and select the Nvidia GPU in the the Run with graphics processor menu:

Run with high-performance Nvidia processor (GPU)


OS X

Install the latest Nvidia Driver for you graphics card. You can download them from the Nvidia website.

  1. Open the CUDADriver.pkg file by double clicking it.

    enter image description here

  2. Go through the installer.

    enter image description here

  3. If it installed correctly, there should be a new CUDA option in the System Preferences (the only time you need to go here is to install updates):

    enter image description here


Finally after you have installed your driver:

  1. Restart your computer

  2. Start Blender.

  3. There should now be an option in the Blender's settings allowing you to select CUDA and your GPU:

    enter image description here

  4. Then select the GPU in Render settings > Render > Device:
