Hi, I am trying to modify the tutorials that come with directx to make a very simple 3D Engine that is able to display and perform operations with meshes. My problem however iis that the performance seems to top out between 500-1000 vertices (600-1200 faces), I''m using 18 textures, stored in 3 .bmp files. This is in windowed mode, culling is on, lighting is on (but only ambient lighting). Do I miss something obvious ? Can I expect a performance boost if I switch to fullscreen mode and how big would it be ? I didn''t expect to meet the limit this early... .

Make sure hardware vertex processing is on (do a search in the code for "D3D_SOFTWARE_VERTEXPROCESSING" and change the "SOFT" to "HARD".

I probably should stop, My doctor says I have the wrists of an 80-year old

Thank you, indeed I forgot something obvious it seems
