i have a strange problem... i'm making a 2D game with Direct3D 9, i'm using Textured Quads. On ATI this work perfecly but on GeForce 4 or TNT2 M64 the pixels seems to be perturbed....does anyone know what's this problem and how to solve it ?

Weird... are you using a filter?

And the rockets' red glare, the bombs bursting in air,gave proof through the fight that our flag was still there.Oh say, does that star-spangled banner yet waveover the land of the free and the home of the brave?

how that ?? i have that.
i don''t use filter i think

d3dDevice->SetRenderState( D3DRS_LIGHTING, FALSE );
d3dDevice->SetRenderState( D3DRS_ALPHABLENDENABLE, TRUE );
d3dDevice->SetRenderState( D3DRS_SRCBLEND, D3DBLEND_SRCALPHA );
d3dDevice->SetRenderState( D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA );
d3dDevice->SetTextureStageState( 0, D3DTSS_ALPHAOP, D3DTOP_MODULATE );

d3dDevice->SetSamplerState( 0, D3DSAMP_MINFILTER, D3DTEXF_NONE );
d3dDevice->SetSamplerState( 0, D3DSAMP_MAGFILTER, D3DTEXF_NONE );

I mean... when you render, do you use a filter, like a linear filter?

It''s the code of my blitter, at the end there is the fillVertice methode of the sprite

This has to do with the problem of pixel center not being well defined in Direct3D texturing. They were supposed to fix that in Direct3D 9, but it could be either that the spec is still broken, or that one of the vendors doesn''t follow it.

The typical work-around for bad texture pixel centers is to add 0.375/texture_width to all "u" texture coordinates, and 0.375/texture_height to all "v" texture coordinates.

Another possibility is that it''s the framebuffer pixel center which isn''t lining up, and you should add 0.375 to all your x and y coordinates.

yes that''s work perfecly thx
