MechDesigner is a 3D application. Ideally you should have a fast CPU, lots of RAM, and your video card and video card drivers should be 100% OpenGL compliant. MechDesigner is extremely efficient and can show your mechanisms faster than any other CAD software product - we believe, but prove us wrong. As such, you can run MechDesigner very effectively on 'low' performance systems. However, it is mainly the appearance of some of the graphical representations where MechDesigner appears to be struggling. This is where you might need to know about how graphic cards work and why you might consider getting a better one.
OpenGL is an industry-standard. Most Microsoft Windows operating systems come with a Software OpenGL driver. We recommend a Driver better than version 1.5, and better than version 3.0 is even better.
Many video card manufacturers have cards to support the OpenGL standard. These cards render and perform calculations using a chip called the Graphics Processing Unit or GPU. This is instead of the CPU. These chips significantly enhance OpenGL performance. This performance enhancement is known as Hardware OpenGL Acceleration.
MechDesigner uses the hardware acceleration if your computer has a OpenGL compatible video card.
Some 3D drivers in the consumer video card market are 100% OpenGL compatible and can use this feature. However, incompatibility problems occur requiring a fix from the video card manufacturer.
PSMotion recommends that you display colors to a 32-bit color depth (using Control panel > Display Properties) to ensure that your MechDesigner renders accurately when using hardware acceleration.
MechDesigner cannot control the quality of the OpenGL driver on your computer system or that MechDesigner will work with hardware acceleration on your system. After all, video card device drivers are proprietary to the manufacturer of the video card in your system.
We recommend you try MechDesigner as a Trial before you buy. If only to ensure that the graphics works well with your PC system.
