I know it's not safe to create/lock D3D resources on a different thread. But I'm just curious if it's ok to do so with resources in D3DPOOL_SCRATCH ? It seems to work from what I've tested so far...
Example: I'm creating a texture in D3DPOOL_SCRATCH on a separate thread and locking it. Then I'm using the pixel data to perform some calculations and finally unlock and release the texture. I'm using D3DXCreateTextureFromFileEx for convenience and I'm not sure if it's safe here.
Any help of an expert would be really appreciated.
