Will Blender work on my system?
Currently, there are versions of Blender available for Windows (2000,XP, Vista), Mac OS X, Linux (i386 and PPC), Irix 6.5 and Solaris 6.8. You will also need an OpenGL compatible graphics card, preferably from a quality vendor such as NVidia or ATI.
Why does Blender not start/display strange colours/show a blank screen?
There is probably a graphics card compatibility problem. Make sure you are using the most recent display drivers for your system. See here for more information on graphics card compatibility.
The Blender screen is blurred and unreadable. What can I do?
This problem is caused by having hardware anti-aliasing turned on for OpenGL applications. Since Blender uses OpenGL for its 2D display, anti-aliasing will interfere with Blender’s operation. Please turn off OpenGL anti-aliasing in your graphics card driver settings to correct this behaviour. See here for more information on graphics card configuration.
Blender is running slowly. What hardware can I upgrade for better performance?
Different parts of Blender are dependent on different pieces of computer hardware. A faster CPU and more RAM can help to increase rendering speed, while the speed of the Blender interface, viewports and real-time engine is influenced by the speed of the graphics card. Fast and large hard drives can also speed up work when dealing with large video files.
Blender gets slower and slower, I have an ATI video card?
It appears that Blender gets slower and slower on ATI cards with the catalyst drivers version 3.10 (or so) and later. The quick fix seems to be to use older drivers (at least for the opengl driver).
Update: many users reported that new ATI drivers (Catalyst 8.x, oct 2008) fixed this issue.
