Stellarium older version1/13/2024 ![]() You may check for graphic-related problems in the logfile (linked from the start menu). So, if the OpenGL version keeps showing problems (message about "Insufficient OpenGL support" at startup, crash just seconds after launch, or graphical errors like broken screen fonts, planets not rendered. MESA can make use of multicore CPUs, so if you have an older multicore CPU, performance may be OK. Of course, this lack of dedicated hardware means a severe slowdown, but a slow system may still be preferrable to a dysfunctional one. MESA totally circumvents the GPU, all graphics is rendered with the CPU (Central Processing Unit this is the device referred to as "Pentium", "Athlon", "Xeon", "Core i5" etc.) only. 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.įor systems without hardware capable of supporting OpenGL2.1, we provide a Windows build that includes the MESA software OpenGL2.1 library. In doubt, you can verify your GPU's capabilities with tools like "GPU Caps Viewer" (free download). (Sometime drivers for notebooks can only be found at the respective notebook manufacturer's support websites.) Any recent hardware should provide this functionality, but you may need to update the driver not just with the built-in Windows Update driver search, but with drivers downloadable from the graphic card manufacturer's website. This normally utilizes a dedicated piece of hardware, the Graphics Processing Unit (GPU). The most critical is that rendering requires OpenGL2.1 support.
