CrossFire support?

Is it always 14x as maximum AA for any video boards?
Guyz please check this one too,
Enable CF, then look for Catalys regitrsy path in ATT SysInfo , open regedit and locate that path. Look for AntiAliasSamples_SET. Double click on it. Now you can see what kind of AA supported by board. I just want to know. Is Catalyst update that value after enabling CF or not. If not, so I must manualy add thouse extra AA modes.

 

I have included two screenshots showing the registry value you asked for Ray and the other with both CCC and Tray Tools on screen showing their available AA options. When running X1900 crossfire it always goes up to X14 AA, Im not sure about the other cards that can be used in Crossfire.

 

x1800, x850, x1900... all max 14x AA.

Guess, all CF-Mode-Atis supports 14x

 

2 Deeko - Can you please apply 14x in CCC and then check again registry for value AntiAliasSamples?

 

Here it is Ray, 16xaa applied :

 

Strange It doesn't applied to the registry values. May be this is sum of AA for master and slave board? There are should be 4 registry pathes , 2 for master and 2 for slave board. Same path but different digits. Can you check AntiAliasSamples for second card to after applying 16xAA?

 

Im not quite sure I understand what you mean Ray, when I apply 14xAA it gets applied to both cards, I cant select each card seperately in the CCC, its just eh Crossfire Master card edition that shows in CCC.

 

I tracked the registry while enabling/disabling Crossfire. Maybe you'll find something usefull

Hmm. Only one registry value MVPU
0-no CF
1- CF enabled
Can you guyz check this:
Disable CF in CC. Open regedit and change MVPU from 30,00 to 31,00 and then Reload display driver in ATT Displays menu. Then check is CF enabled now or not. CCC may not show current changes so you have to check it in games or in any opther applications.

 

strange result (after manually setting mvpu from 30 to 31)




after closing CCCC mvpu has been set automaticly back to 30, but if I restart CCCC, I get same "result" seen on the pic.
I had to completly quit and restart CCCC to get the "normal" menu back.

 

any progress?

 

Not yet guyz. It seems that this is not so easy. Even if you see only one check box in CCC, interbaly there are a lot of information should be checked before attempting to enable / disable CF.

 

Thanks for continuing your efforts for this Ray, its much appreciated. Please post back if and when you require any more data regarding Crossfire.
