I remember Corysama told what on PS2 polygons rasterised by one at time. I have some questions about that.
1) Did all polygon rasterised and textured all in one go or by 8 pixels clock (because there is 8 pixel pipelines what can texture)?
2) After rasterisation that polygon is written to back buffer, but did it also written to z buffer?
3) If as Corysama said polygon not only rasterised but also textured, did that mean what textures is written to EDRAM befor display lists are sent?
4) If that polygon should have, let's say two passes, after it rasterised, textured and written to back buffer, VU1 send that polygon to GS again, did GS need that polygon what is already in back buffer read it and blend in with second same polygon for second pass?
