AA with HD4870 CF

[ShaneEire]

I just cant get Anti-Aliasing to work with my two HD4870 cards in crossfireX.

Its actually been ****ing me off alot lately, games like Stalker,Crysis Warhead,Spore and many more.
I have tried various dirvers 8.6-8.9 catalyst and all the same. I'm not sure if its a well known CF problem that Im not aware of, or whether there is a simple fix that I am not aware of either.

I have messed with Catalyst AI and all the other options, disabled AA in CCC and enabling it through game options, and vice versa putting it on in CCC and leaving it off in game options or for games that dont have that graphic options(spore ect)

I've tried various levels of AA and with all the messing about I still cant get any results.

The only game that seems to work with AA is Team Fortress 2 through its in game options, but other games using same engine like HL2 doesnt work the same way, so Im pretty clueless. Im hoping someone has the same problem and knows a solution because I know the 4870s are popular cards.

Im using DX9 WinXP, Dual core E8500, 3GB RAM, 2x HD870 in CF.

Thanks...

When you uncheck HD-AA and slide the bar all the way over...does it allow you to use the drop box to select "wide-tent" and if so does it show up as 32x?

yeah theres 4 options I think, box, narrow tent, wide tent, edge effect.

You have to actually slide it over to 16x then the drop box will only have 3 options...the highest being wide-tent at 32x...if it does not show just like that...then there is a issue with CCC...

it works with my xfire setup too and all the ccc settings are on default...

btw in stalker if you set everything at the highest with a high resolution the last thing you want is aa lol...

They key thing on making sure that is working the way I stated is that is also one way to make sure CF is truely engaged...if it wasnt you would of only seen 16x and that could of been a issue why AA wasnt working correctly...

I can set AA thru game and it works and I can add any level in driver and it works, cod4 crysis are all I have tested here lately though.
