Exception in reach profile (samplerstate?)

Apr 19, 2012 at 9:35 PM

I am currently running krypton in reach profile. Whenever I drag my game window around I will get the following exception at KryptonRenderHelper.cs:

"XNA Framework Reach profile requires TextureAddressMode to be Clamp when using textures sizes that are not powers of two."

I tried playing around with mGraphicsDevice samplerstates, but it didn't help. Any help would be greatly appreciated!


Best regards,

This is probably due to the fact that the render target you are using is not a power of two.

Krypton may be responsible for this.

When Krypton generates the render target for the shadow generation, I believe it uses the current back buffer size, and simply copies that. Instead, you could calculate the next power-of-two size up from the backbuffer's size, and generate the backbuffer with that size instead. Although this may make more problems.

Unfortunately, I don't have the time right now to fix this issue. Is is possible to use the HD profile, at least temporarily?

I can keep working under Reach profile.

The error occurs only when the game screen is moved/dragged onto another monitor screen (I am using two monitors in extended mode).
