  • Improved: Smart transparency effect (aero effect) was rewritten for NVIDIA GPUs. The improvements are:
    • it renders the texts inside the window much better than before. the accuracy of the new algorithm is on average 95% for programs such as text editors, word processors, a code editor, and more.
    • The new algorithm to detect and rerender text pixels is rendering much faster due to:
      • Uses much more GPU cache memory than global memory
      • The new algorithm uses a different image processing & recognition technique that works much faster than ever
      • It uses new API to get the window image that included in Windows 10 version 2004
    • The new smart transparency/aero effect will not take 20% CPU usage or more for the average computer because it uses the NVIDIA GPU for the rendering process. It will take up to 5% CPU usage and up to 10% GPU usage (tested on NVIDIA GTX 1050TI) so that the computer fan noise will not be high as before
  • Dark Mode and Smart transparency effect (or aero effect) will work faster also when no NVIDIA Graphic Card is available thanks to new API in Windows 10 update 2004. But the improvements will be much noticeable on with NVIDIA GPU
  • A lot of other bugs fixed before while testing this release
