Laggy XV rendering

Hello, after I upgraded to Catalyst 8.8 I experience the XV- and 2D rendering to be very laggy first when XV is beeing, and even after I closed MPlayer, the 2D rendering is still laggy for a little while.

Anyone found a workaround for this?(yes I know it's not a long time since this driver was released).

Yes. I have issues with xv as well with catalyst 8.8 and Radeon HD2900Pro . When I play movies they tend to freeze for a second or so from time to time. Hope this issue gets resolved soon. Everything worked just fine with 8.7.

Re: Laggy XV rendering

I'm not sure if this is the exact problem you're talking about but try adding "nopat" to your kernel line in Grub.  Mine looks like this now:

ktitle  Arch Linux
root   (hd0,0)
initrd /boot/kernel26.img
kernel /boot/vmlinuz26 root=/dev/disk vga=791 ro nopat
initrd /boot/kernel26.img

This fixes a pause I get every few seconds with the new driver.

I'm going to give this a try too. Out of curiosity, what does the "nopat" entry do?

EDIT: I don't know what it does but it fixed it for me too. Thanks Luciferin!

Re: Laggy XV rendering

It fixed the issue for me too. However I feel that this workaround should not be considered the permanent solution and the driver should be adjusted to work properly with the default kernel configuration.

Re: Laggy XV rendering

That would be ideal. Hopefully, ATI won't wait to fix this because not everyone is going to know how to fix it.
