AMD does not use any kind of strong-armed tactics, in fact it's against their internal code of conduct, all the evidence for Nvidia's strong-armed tactics is well documented during the geforce 6000, 7000, 200, 400, 500 & now we are seeing it again.
A few examples are the 3DMark benchmark scandel, & in he early 2000s where Nvidia strong-armed the developers into not supporting ATi's far superior anti aliasing implementation in-games.
Nvidia in fact does not offer less problematic solutions, as evidenced by the catastrophe that is the 312.08 drivers that killed cards.
I have no loyalty to any company, but I refuse to support any company that harms the customer, Nvidia continually does things to harm AMD customers, if you call that better driver support then you have bought Nvidia's PR.
I bet you've never owned a crossfirex setup, AMD did in fact have a stutter free experience through their RadeonPro software, the software is in fact developed by indepednent fans but all of its features were implemented with the help of AMD engineers.
Where do you think Nvidia got Adaptive V-Sync from ? it was stolen from RadeonPro, AMD users had access to dynamic V-Sync for over 4 years.
The only reason people like you buy Nvidia cards is because they feel elitist by doing so, they feel like the big green bully is their friend & when that big green bully starts beating up on the small red folk you stand and applaud, disgusting.
