This version requires .NET 3.5! and ONLY works with drivers from the 185 series or those > than (e.g. 185.66/68, 186.xx, etc.)
Special handling of cards prior to the G80 (8x00 line) has been removed.
nHancer will still work with older cards, but not all Anti-Aliasing options will work correctly with them.
Please also note that this an early beta version that's primarily released so people can use nHancer with the latest GeForce drivers.
It can't damage your system in any way, but not all functions might work correctly and you might find bugs here and there.
