The ATT link you gave us will not install for Vista 64 user. It says it needs access to a low level drive which Microsoft doesn't allow us to have access to.
Is there another tool to use or some way to easily install ATT?
On mine (and I presume other's) Catalyst program, we do not have the option to turn on Geometry Instancing. After talking with Dell for 2 hours, they suggested I call ATI support. Too bad ATI is closed on weekends. (supposidly this is a "known issue"[the GI thing, not them working banker's hours])So I scoured the internet to see if I could find anything. Long story short, ATT tries to hook itself to a low level driver and Windows Vista 64 SP1 does not allow a driver that is "unsigned" to do this. It costs lots of $$ to get the ATT tool to get a signiture, so don't expect it any time soon since it's from an independent person. However, after a LONG search, I finally found this forum:
This allows you to install and run ATT (the tool the OP was suggesting we use). I have since used this and got the ATT to install and turned on Geometry Instancing. I spent the next 4 hours playing Demigod (yay DotA on steroids!)
*WARNING: McAFEE CONSIDERED THIS A TROJAN* and would not allow it to run. I had to turn it McAfee off to run it the first time (I then turned it back on). This is probably because it goes around the whole sign/unsigned stuff. I'm using it successfully, but of course use at your own risk! If I find any kind of reason not to trust this, I'll edit this post appropriately.
hope this was helpful to anyone else experiancing this mess.
For reference I have the 4850 ATI Radeon Card and lastest drivers I tried were from 5/15/09. (funny how this game says ATI on the back, but my higher specs then reccommended ATI card doesn't work. Ah well)
