So I splurged on a 6970 yesterday and I'm pretty much enjoying it other than the annoying task of needing to uninstall/reinstall several of my games to get them to work again. (I realized afterwards that every game that had this issue either uses the software version of PhysX or had some kind of activation-based DRM so I probably just needed to reinstall the PhysX software to solve my issues with the former.)
This thing is way quieter and cooler running than my previous card so I'm already happy about that. That MLAA option is a freaking godsend in games like GTA IV and Dead Space that won't allow any other AA option to work, too.
However, I've been using Nvidia cards for the last decade so I have a few questions about the ATI drivers that I'm unclear on:
1) Based on the description, I'm assuming that "Adaptive AA" is similar to the "Transparency AA" setting in the Nvidia panel. Is this correct? Also, will it automatically implement Adaptive AA if I have that selected in the control panel, even if I also have it set to use the AA option in the application or do I have to force it?
2) The only thing I miss about Nvidia is the gimmicky crap. Has anyone had an experience using the Hybrid PhysX mod? Going with a 6970 instead of a 580 leaves me with enough to get a GTS 250 or something off ebay, but I'm worried that it's an unreliable mess or an extraordinary hassle to get working.
