Choppy Youtube with Hacked 4870

[freeman727]

Hey All,

I could not find an answer on prior posts. I have a hacked XFX 4870 rev ZWFC (using Cindori method) and OEM GT120 plugged in. When I run hi-def youtube videos on the GT120 it runs smooth as butter. When I run the same videos on the 4870 it is choppy like it was from a computer 10 years ago. Do I have to reflash it to a newer hacked firmware?

Thanks a bunch Cindori! I'll give it a go.

That kext edit did not seem to do the trick. I have a hunch it was a 10.6.3 or 10.6.4 update issue. I'll try your Zeus program.

I installed all the updates on Zeus to no avail. The 4870 thread described rolling back to ATIRadeonX2000.kext from 10.6.3. Anybody know where I can obtain them?

Consider this thread closed. Used the solution found on https://forums.macrumors.com/threads/943259/

I had to install and then reinstall the updater before the problem was solved. Quartz driver went from NO to YES on Zeus.

I hope this has helped someone. I don't get why Apple is ***** us with each update. I guess they don't like hackers like us.
