[QUOTE="tourettes, post: 259329, member: 10858"] Findings part II: in fontEngine.dll :: void FontEnginePresentTextures() [code] for (int i=0; i < textureCount; ++i) ... texture->pVertexBuffer->Lock( 0, 0, (void**)&pVertices, 0 ) ; memcpy(pVertices,texture->vertices, (texture->iv)*sizeof(CUSTOMVERTEX)); texture->pVertexBuffer->Unlock(); [/code] I guess thats where the multiple lock warning is coming from. Could someone who has actual DX side knowledge have a look into these two findings? One pissible way tor getting a rid of the locking issue: [url=http://msdn2.microsoft.com/en-us/library/bb147263(VS.85).aspx]Performance Optimizations (Direct3D 9)[/url] / "Using Dynamic Vertex and Index Buffers" [/QUOTE]
