Thanks for the feedback Shadow, I actually heard bad things about this driver(in guru3d forums) about both performance and trouble in installing, but your post made me feel better So,I'm going to try it out and will post the results soon
Good download results for my 5770.
Installed the "new look" version and I like it. Navigation is fast and easy.
Settings are the same as before. So far, no issues, although my card isn't high on the list.
So I installed 10.12 (new CCC preview driver) and had the bad flickering again. I was going to edit the default profile, but the only clock references I saw were for Overdrive, and I couldn't even figure out how to add a profile for clocks as in the old CCC.
Also, I had lots of trouble getting the CCC to function. It would open once, then fail to close properly (Windows would ask if it shutdown abnormally) and then I couldn't get it to open again without a reboot.
I've been using 10.12 with the new catalyst for a while now. No issues installing and seems to run fine on my 4850, though sometimes it disappears/doesn't start. Maybe that is th way the new one works - only comes up when you need to change something (like NV).
So I should amend my last statement about the mouse corruption occurring: While it did happen again (several times) the last time it happened...something magical and wonderful happened. When i moved the cursor from one display with corruption to the other, the mouse appeared normal (and this is the old driver's behavior). However moving the mouse back to the origional (corrupted) display, the mouse was restored!
Not sure what this means for people with single displays but experience mouse corruption, but this is slightly better behavior, but I really wish they would quash this thing once and for all.
Well it installed fine. I'm not a big fan of the layout, I'd prefer if it was a bit easier to get into the settings I want to change but it's not so bad.
One thing I noticed is now my screen likes to flicker/jiggle at times. Not really during normal use but definitely at start up and I think at shut down too it like... vibrates left/right like it's trying to align or... something. It's wierd. But it does work just fine after that happens, I just never saw it do that previously.
