Written in c# for .Net 4.8 (.Net 4.0 minimum supported). No external components\libs used. No DirectX support, almost no other optimization. Seems like modern PCs can handle it on single core above 3GHz. Tested on my setup is 3 x 2560-1440 + 1920-1080 @ RTX2070 Super & I7-10700K, and I have about 5% CPU load and 15% GPU load.
