Troubleshooting Graphics Hardware
|
|
*********************************
|
|
|
|
Blender makes use of OpenGL, which is typically hardware accelerated.
|
|
|
|
This means issues with the graphics card hardware and drivers can impact on Blender's behavior.
|
|
This page lists some known issues using Blender on different graphics hardware and how to trouble-shoot them.
|
|
|
|
|
|
Performance
|
|
===========
|
|
|
|
When the entire interface very slow and unresponsive *(even with the default startup scene)*.
|
|
This is likely a problem with the OpenGL configuration.
|
|
|
|
Unfortunately in this situation you may have to do some of your own tests to find the cause,
|
|
here are some common causes and possible solutions.
|
|
|
|
Upgrade your OpenGL Driver
|
|
If you're experiencing any strange graphics problems with Blender,
|
|
its always good to double check you're using the latest drivers.
|
|
Disable Anti-Aliasing (:term:`FSAA, Multi-Sampling<FSAA>`)
|
|
See :ref:`Invalid Selection, Disable Anti-Aliasing <troubleshooting-3d_view-invalid_selection>`.
|
|
Change the *Window Draw Method*
|
|
This is set in the :ref:`system preferences <preferences-system-window_draw>`.
|
|
Its selected automatically, however when experiencing problems its worth
|
|
checking if changing this resolves interface drawing problems.
