Although this can be done at a lower resolution, it is still quite expensive. The game was approved by GT Interactive in 1996 and released on May 22, 1998 to the world, however by several accounts work on the engine actually started sometime around 1994. The latest rendering features in X-Plane 10 (HDR rendering, global shadows, and water complex water reflection) can be very costly on older computers. An example is here. i click play and its says its running but nothing happens at all. Since the water usually lies in the horizontal (XZ) plane, this is no harder than multiplying the modelview matrix with a negative vertical scale (-1 value for Y coordinate). A simple reflection can be calculated by raymarching off the surface normal, and blending the result together with the surface color. The material reacts to lighting conditions accordingly. This implementation is not perfect but, it's open source so anyone can contribute to it and make it better. And How Does It Work Under Water? The best way for a good timer to operate is to use the QueryPerformanceCounter(). I also tried this shaders in Render Monkey and the result is the same.
