I'm trying to find how to render everything with software in XNA, but I can't find what option I need to set.

I'd like to know which method/properties I have to call/set to make my app run in software mode as opposed to hardware accelerated mode.

It looks like you can use the reference device in XNA 4.0 using this code:

GraphicsAdapter.UseReferenceDevice = true

Not sure if this works but that is what the MSDN says.

There's more on how to use this here: stackoverflow.com/questions/4751820/… – Cypher Sep 12 '12 at 19:11

Except for maybe debugging shaders why would you want to use software rendering?

You can use the Reference Device but it is extremely slow. I don't normally work in XNA but a quick google found me this: How to: Use the Reference Device

that code does not compile. GraphicsDeviceInformation does not have CreationOptions, DeviceType & PresentationParameters properties – ProgrammerAtWork Sep 12 '12 at 18:58
btw, I want it to check if some problems are caused by my graphic card or my program. – ProgrammerAtWork Sep 12 '12 at 19:02
@ProgrammerAtWork ah ok, sorry it looks like the link was to XNA 1.0 but SomeWritesReserved found the correct one. – NtscCobalt Sep 12 '12 at 20:29
"I want it to check if some problems are caused by my graphic card or my program" - you should have probably added this to your question otherwise you had a high risk of getting many more similar answers. – mh01 Sep 12 '12 at 21:53

There is this Windows Advanced Rasterization Platform on the most recent Windows platforms which i think it's what you are looking for or there are commercial solutions like Pixomatic.
