World's First: Direct2D Hardware Acceleration for a WinForms Spreadsheet — ReoGrid One 5.2
ReoGrid One 5.2 gives its WinForms control a Direct2D renderer, making it the first WinForms spreadsheet component to draw with Direct2D on the GPU (our research, as of October 2026). One property turns it on, and a full repaint while scrolling drops from 3.6 ms with GDI+ to 1.0 ms. The same release makes each frame about 7× faster on WPF and up to 8× faster on Avalonia, and draws sheets with tens of thousands of merged cells about 16× faster. All of it measured.
