Great. > We just need to add the fifo check now. I've just add it but it makes gears drop from 222 to 185 fps in my system. I don't know if this is caused by droped triangles when there is no FIFO check, or if the FIFO check makes a big overload. So I #ifdef'd it out. Note that I even avoided to use udelay or any other time function, but it didn't help. > > So I'm going to start looking at how to set up the ring for the > descriptor tables, and maybe hack around on AGP textures some more.
