I realy don't know what is real problem because the Attila's patch
that fixes the problem is practicaly moving the XV buffer to VRAM that
should be very slow for everyone. I can later today upload a test
application to see how fast memory access is to VRAM. But I still
don't understand why GPU reading from GTT is very slow for X1300
(laptop card?).
