Nov 26, 2018 i believe from research that it supports shader model 4.1 but as already stated, not DX11 only DX10.1 you will need to buy a dedicated graphics card to run this game or buy a newer cpu with higher DX capability. 4 DirectX9 based rendering engines are available for different types of hardware, starting with DirectX7 and up to Shader Model 3.0 The source code is written in C, divided among 22 classes. Rendering uses DirectX9 libraries. Shaders are written in HLSL. Aquatica engine is fully object oriented.

The unified shader model uses the same hardware resources for both vertex and fragment processing.
In the field of 3D computer graphics, the unified shader model (known in Direct3D 10 as 'Shader Model 4.0') refers to a form of shader hardware in a graphical processing unit (GPU) where all of the shader stages in the rendering pipeline (geometry, vertex, pixel, etc.) have the same capabilities. They can all read textures and buffers, and they use instruction sets that are almost identical.[1]
History[edit]
Earlier GPUs generally included two types of shader hardware, with the vertex shaders having considerably more instructions than the simpler pixel shaders. This lowered the cost of implementation of the GPU as a whole, and allowed more shaders in total on a single unit. This was at the cost of making the system less flexible, and sometimes leaving one set of shaders idle if the workload used one more than the other. As improvements in fabrication continued, this distinction became less useful. ATI Technologies introduced a unified architecture on the hardware they developed for the Xbox 360, and then introduced this in card form in the TeraScale line. Nvidia quickly followed with their Tesla design. The concept has been universal since then.

Early shader abstractions (such as Shader Model 1.x) used very different instruction sets for vertex and pixel shaders, with vertex shaders having much more flexible instruction set. Later shader models (such as Shader Model 2.x and 3.0) reduced the differences, approaching unified shader model. Even in the Unified model the instruction set may not be completely the same between different shader types; different shader stages may have a few distinctions. Fragment/pixel shaders can compute implicit texture coordinate gradients, while geometry shaders can emit rendering primitives.[1]
Unified shader architecture[edit]
Unified shader architecture (or unified shading architecture) is a hardware design by which all shader processing units of a piece of graphics hardware are capable of handling any type of shading tasks. Most often Unified Shading Architecture hardware is composed of an array of computing units and some form of dynamic scheduling/load balancing system that ensures that all of the computational units are kept working as often as possible.
Unified shader architecture allows more flexible use of the graphics rendering hardware.[2] For example, in a situation with a heavy geometry workload the system could allocate most computing units to run vertex and geometry shaders. In cases with less vertex workload and heavy pixel load, more computing units could be allocated to run pixel shaders.

While unified shader architecture hardware and unified shader model programming interfaces are not a requirement for each other, a unified architecture is most sensible when designing hardware intended to support an API offering a unified shader model.

OpenGL 3.3 (which offers a unified shader model) can still be implemented on hardware that does not have unified shader architecture. Similarly, hardware that supported non unified shader model APIs could be based on a unified shader architecture, as is the case with Xenos graphics chip in Xbox 360, for example.
The unified shader architecture was introduced with the NvidiaGeForce 8 series, ATIRadeon HD 2000, S3 Chrome 400, Intel GMA X3000 series, Xbox 360's GPU, Qualcomm Adreno 200 series, Mali Midgard, PowerVR SGX GPUs and is used in all subsequent series.
