This makes PixInsight a demanding application regarding free disk space requirements.The macOS and Windows versions are ports of the main development trunk on LinuxFreeBSD.These are the platforms where youll get the best performace, stability and user experience with current versions of PixInsight.Note also that any existing 32-bit version will no longer be supported or updated.
Pix And Windows Download From OurNo 32-bit version of PixInsight is or will be available for download from our servers. Many users report that they are using current 1.8.6 and 1.8.7 versions of PixInsight on Windows 7 SP1 and Windows 8.1 without problems, but we no longer test the application on these Windows versions. This means that we cannot guarantee that current PixInsight versions will still work correctly on Windows 7 SP1 and Windows 8.1. There are specific preferences settings to control the maximum number of processors used by PixInsight, along with other parallel execution options such as thread execution priority, thread processor affinity, etc. The recommended practical minimum for production work is 32 GiB of RAM. It will use all memory available to applications, and will cause the operating system to allocate virtual memory on disk when necessary. For serious image processing, working with large monitors is a real must with PixInsight. Note that this refers to logical resolutions, not physical (for example, a Retina display with 28801800 native resolution has 1440900 logical pixels). Pix And Windows Manual Adjustments SuchThe application will run on smaller resolutions, but you may need to perform manual adjustments such as closing control bars and explorer windows, or changing automatic high-dpi screen and font management settings. Even with manual tuning, PixInsight has not been designed specifically to work on very small screens. This means that several monitors should be distributed horizontally with the applications main window located on the leftmost monitor. For example, a dual monitor desktop configuration with a 5K display (51202880) and a QHD display (25601440) is not supported. The application will work, but windows will be scaled to match the 5K display, and they will look huge when moved to the QHD display. Sorry for the inconvenience if you are affected by these restrictions. Hardware-based compositing, such as OpenGL, is a precondition to run PixInsight on all platforms. This should be no problem at all on any modern X11 desktop. As an exception, the KDE desktop environment allows you to use software-based compositing (XRender) on systems without hardware acceleration. However, XRender allows you to run PixInsight on a virtual machine where the virtualization system does not provide video hardware acceleration to guest operating systems. We have plans to implement GPU acceleration in PixInsight, but currently we have much more important priorities, including evolving our development platforms, and the design and implementation of new image analysis and processing tools. In addition, more space is required during file writing operations because of disk IO security strategies (basically, when an existing file is rewritten a temporary copy of the original is kept during the whole disk write operation). ![]() CCD camera. In addition, PixInsight can store an unlimited number of history states (unlimited undoredo operations).
