以编程方式为显卡注册应用程序

Question

I am trying to write a Setup for an application with Inno Setup, which is pretty neat by the way ;) , but now I am stuck with a problem regarding the graphiccard.

I am installing a 3D application and want to configure the program so that it uses a certain graphic card as default. It sounded logical to me that somewhere in the registry must be a something to configure that. I tried to change the default graphiccard manually und compare the changes in the registry but couldn't find any entrys relative to the changes

I know that programs like Adobe Photoshop are using the high performance graphiccards by default so there must be some kind of solution to my problem.

I am using inno script to write my setup but I can call external programs to do some tasks so I could write a C# program to execute this task.

This option is mostly relevant for Windows 7 and Windows 8 because I only saw it there.

Does anyone of you know how to change the default graphiccard of an application programmatically?

Answer 1

Your approach, sorry, sucks. This is not something you should do during setup. What if the card changes?

Check it during application start. Let the user choose if you do not find anything. Let him update. Not everyone has only one graphics card. People do update the graphics card. Why should I rerun setup just to get this done?

And it is quite easy to identify graphics cards, performance is another story. Which one is "high performance" in your eyes?
