Hi ! Does anyone know if fast z-buffer clears and ’z-compression
aka hyper-z’ are going to be implemented in radeon DRI drivers (actually
it is in the ’radeon’ kernel module). It seems to be one of the
areas where major performance gain could be achieved, taking this driver to the
same performance level as ATI’s binary only driver has. I’ve done
some perf. tests and by disabling z-clears frame rates almost double, which
shows that the current approach by drawing a dummy quad is very slow ... I
would be willing to implement it myself if anyone would tell me where to find
information about programming this feature. Regards, Vahur Sinijärv Cydonia Ltd. Pärnu, Estonia |
