I bought a game in APPSTORE yesterday. At the first launch, a message about the absence of 'SHADER MODEL 3.0' popped out. I have an AMD Radeon HD 6750M graphics card. There is no card on the driver page. How do I start the game? My computer is an iMac 21,5' from 2011 with the latest operating system. I know that shader model 2.0 and 3.0 is for directx 9.0c and shader model 4.0 is for directx 10 and shader model 5.0 is for directx 11. But I just want to for now know the difference in 3.0 and 4.0 since that's what my video card is only capable of.
What Is Shader Model 3.0
What Is Shader Model 3
Shader Models are components used to help render graphics sent from the CPU to the graphic card. The version of shader model your computer can support is based in the combination between your DirectX version and the version your graphics card can support.
It is important to always have your DirectX updated to the latest version you can do so by clicking here: Download DirectX
Please note DirectX versions prior to DirectX 8.0 do not support shader models
• DirectX 8.0 - Shader Model 1.0 & 1.1
• DirectX 8.0a - Shader Model 1.3
• DirectX 8.1 - Shader Model 1.4
• DirectX 9.0 - Shader Model 2.0
• DirectX 9.0a - Shader Model 2.0a
• DirectX 9.0b - Shader Model 2.0b
• DirectX 9.0c - Shader Model 3.0
• DirectX 10.0* - Shader Model 4.0
• DirectX 10.1* - Shader Model 4.1
• DirectX 11.0* - Shader Model 5.0
*DirectX 10.0 and higher will not run in Windows XP
Please remember that your version of Shader Model doesn't just rely on DirectX, but also the hardware version of your graphics card. So if your graphics card only supports up to version 2.0, and you have DirectX 10.0 installed. You can still only play games that support up to Shader Model 2.0
The best way to tell which version of Shader Model is supported on your graphics card is to visit the manufacturer's website and inspect the specifications of your card. If you still have to box the card came in, it may also say on the back of the box.
Bounty Hounds Online has a minimum requirement of Shader Model 3.0, so if you do not meet that requirement you will get the error message 'ERROR: Does not support Shadel Model 3.0'.
If you are getting this error, then please update your DirectX, if you have the latest version of DirectX then unfortunately you do not meet the minimum requirements to play Bounty Hounds Online.
