   Texture Filtering between DX9 and DX10
  I'm having a strange problem, when i draw two images. One with DX10 and one with DX9 i have different result. See below image for more.The DX10 image is sharp just like the original, the DX9 image is blurred somehow...DX9DX10What can be the cause? (I've checked inside Pix and the image is correct)The states i've used in the hlsl shader are :DX9AlphaBlendEnable = true;SrcBlend = 5;DestBlend = 6;BlendOp = ADD;SrcBlendAlpha = 5;DestBlendAlpha = 6;BlendOpAlpha = ADD;ZEnable = FALSE;sampler samLinear = sampler_state{    texture = <Texture>;Filter = ANISOTROPIC;    AddressU = Clamp;    AddressV = Clamp;};DX10BlendState AdditiveBlending{AlphaToCoverageEnable = TRUE;    BlendEnable[0] = TRUE;    SrcBlend = SRC_ALPHA;    DestBlend = INV_SRC_ALPHA;    BlendOp = ADD;    SrcBlendAlpha = SRC_ALPHA;    DestBlendAlpha = INV_SRC_ALPHA;    BlendOpAlpha = ADD;    RenderTargetWriteMask[0] = 0x0F;};SamplerState samLinear{    Filter = ANISOTROPIC;    AddressU = Clamp;    AddressV = Clamp;};What do you think? Thanks for the help.   
  Resolved using NONE as filter for DX9, now the question is...Why in DX10 Anisotropic works fine, but in DX9 it looks blurry? :D   ;  With the DX9 version, you're probably encountering this.A much better explaination was provided by Drilian here.[EDIT] if you can't figure this out from the articles, you'll need to offset the DX9 version by 0.5 pixels (preferably by shifting the positions of the vertices, though shifting the texture coordinates works too.   ;Quote:Original post by sirobWith the DX9 version, you're probably encountering this.A much better explaination was provided by Drilian here.[EDIT] if you can't figure this out from the articles, you'll need to offset the DX9 version by 0.5 pixels (preferably by shifting the positions of the vertices, though shifting the texture coordinates works too.Thanks, that resolved the issue. :D
