The DriverIdentifier is a tool that analyzes the system drivers on your computer. The utility reports if any new drivers are available, and provides the download files for the driver updates so you can install them quickly and easily.
On Windows this indicates your system may be running in "Mesa Mode". This may happen when hardware rendering is disabled because of missing drivers, or if you don't have compatible hardware-accelerated graphics at all. Your PC may be too old (from 2008 or older, or some netbook with Atom CPU from 2010?) If you have a 3D video card or at least a modern processor (CPU) with built-in GPU capabilities, make sure that your OpenGL drivers are installed and up to date.
Hardware requirements have not changed since V0.13 (see Common problems with 0.13). Stellarium should work on most computers from 2010 and later, and on older computers equipped with dedicated graphics cards from around 2008 or later, when drivers are up-to-date.
Particular note for Windows 10 upgraders: If you upgrade some older computer, you may have to also upgrade graphics drivers manually. Not all graphics card manufacturers provide drivers for Win10 explicitly for their old hardware, but some drivers for Win7/Win8 may work. If Stellarium V0.11 worked for you some years ago, it should work also here. If the hardware allows it, V0.14 will also work. Don't expect latest programs to run on outdated hardware without latest drivers though.
V0.13 is the first release based on Qt5, which brought several technical changes. The most critical is that rendering graphics with Qt5 requires at least OpenGL2.1 support. This normally utilizes a dedicated piece of hardware, the Graphics Processing Unit (GPU). Any recent (say, post-2011) hardware should provide sufficient functionality, but you may need to update the driver not just with the built-in Update driver search of your operating system, but with drivers downloadable from the graphic card manufacturer's website. (Sometime drivers for notebooks can only be found at the respective notebook manufacturer's support websites, and using the reference drivers from GPU manufacturers may not be completely compatible.)
This requirement is valid for all platforms (Win/Mac/Linux, in any flavor). As always, update drivers if you see graphic problems (missing characters, flickering, ...) where there should not be any. Read the log file for warnings hinting at graphics problems. (You find the log file either in the application's help menu, or via start menu->Stellarium->Last run log.)
In doubt, you can verify your GPU's capabilities with tools like "GPU Caps Viewer" (free download). If this shows support for OpenGL 1.4, 1.5 or 2.0 only, and your PC is otherwise still OK, you may consider upgrading your PC at least with a dedicated entry-level graphics card. If this is not possible, read below for MESA support.
We are providing two flavours of Windows versions. One uses OpenGL drivers directly. This should work with graphics cards from AMD/ATI series Radeon HD-2xxx and later, NVidia 8xxx and later, or Intel HD Graphics (built into Core-i processors of the "Sandy Bridge" generation) and later. Make sure you use the latest drivers from your graphics card manufacturer.
The other uses ANGLE, which translates OpenGL to DirectX on Windows 7 and later. Also here we need hardware providing DirectX VertexShader 2_0 and PixelShader 3.0 (vs_2_0 ps_3_0), i.e. DirectX10. This should include even earlier graphics cards: ATI/AMD X1xxx, NVidia 6xxx, Intel GMA X3000. Again, keep your drivers updated! Current trial versions seem to run even on WinXP, but are not 100% stable. ANGLE is officially only supported on Win7 and later, we cannot therefore do anything if it does not work on your particular XP PC.
To remove 90% of the common problems like strange graphics effects after an update to 0.12, or stars rendered as triangles, upside-down sky, strange text characters, off-center or distorted appearance of the sky sphere and other effects:
Problems range from missing parts in the Stellarium interface, text display problems (on S3 and ATI Rage graphics cards), to missing stars. They mostly occur on older hardware, or on specific on-board graphics chips (an onboard Geforce 4MX user solved the problem by reverting to the older 188.8.131.52 driver for his model). We advise experimenting with the graphics driver (updating, changing settings, reverting to older versions) if you're comfortable doing this. For users experiencing problems with S3 graphics controllers, update the driver to the S3 Graphics ProSavageDDR driver for Windows XP.
For all you die-hard XP users: this version (only the "classic" flavour) still even works on XP. Make sure to update graphics drivers though. A Geforce 9600 crashed with 335 drivers, but works with 340 drivers. 2b1af7f3a8
