• UNIGINE 2.9: C# Component System, Better Shadows, SSSSS, Dome Screens Support, Weather Add-On

• Unigine 2.9 Further Enhances Its Stunning Visuals

  It's a pity there doesn't seem to be any new adoption of Unigine as a game engine, but this visually impressive platform does continue seeing much success in the area of industrial simulations, professional VR platforms, and related areas. With Unigine 2.9 this Linux-friendly graphics engine is even more stunning. On the visual front, Unigine 2.9 has delivered better shadows with smoother edges and realistic penumbra. There are also lighting improvements to find with Unigine 2.9, improved screen-space subsurface scattering, better screen-spaced effects, improved tone mapping, faster voxel-based light baking, and other advancements in its visual capabilities.

Linux 5.4 To Expose What's Keeping The System Awake Via Sysfs

The next Linux kernel version will expose the real-time sources of what's keeping the system awake via Sysfs compared to existing source information that previously was only available via DebugFS. With Linux 5.4, wakeup source statistics will now be exposed under /sys/class/wakeup/wakeup*/ for tracking wakeups, their counts, and related bits for profiling the system for power usage optimizations. Suspend-blocking wakeup sources have been available under DebugFS to be useful for bug reporting and analyzing battery consumption. This solidifies the work now under Sysfs with a stable ABI. In addition to the interfaces now stable in adding them to sysfs, it makes them more accessible compared to DebugFS often being restricted to root or other restrictions in place by different distribution kernels.
