Beginner question. Synopsis: my water effects does something that causes the drawing of my sky sphere to throw an exeption when run in full screen. The exception is:

XNA Framework HiDef profile requires TextureFilter to be Point when using texture format Vector4.

This happens both when I start in full screen directly or switch to full screen from windowed. It does NOT happen, however, if I comment out the drawing of my water.

So, what in my water effect can possibly cause the drawing of my sky sphere to choke???

Does your shader change the render states in any way? – ClassicThunder Feb 17 '12 at 14:24

It might be helpful if you could show some code, especially around the area where you hit that error. – Nic Foster Feb 17 '12 at 15:09
Are you using BasicEffect or a custom shader? – David Lively Jul 28 '12 at 20:14
With "water effect" I ment a custom shader. :-) – danbystrom Jul 30 '12 at 6:55

You need to set the SamplerState[0] to SamplerState.PointClamp before your DrawIndexedPrimitive call.
