Dear GPU


DearGPU is a web site dedicated to get answers on typical GPU mysteries.

Which code is faster?
How does it perform on the other vendors GPUs?
Is the feature supported? How is my code affect by the driver version?

You can read about my findings or use the source code of DearGPU to make your own experiments. The simple framework allows for quick DirectX 11 experiments. It also can serve as an example for the code experiemnts. The first example is called "Dither Experiment".
