And so what about AMD users, just not worry about people with AMD cards? heh I'm testing with both NV and AMD today, and will relate the gameplay experience on both in our preview today.
AMD does have a driver for this game BTW - http://support.amd.com/us/kbarticles/Pages/Catalyst1111aperformance.aspx
To be honest, I think most of the issues are game related, this game needs some serious patch work.
Hate to say it... but AMD users are saving money on the cost of their hardware unfortunately it's at the cost of driver development. Nvidia pays for early access to games and to work with early game builds for optimization... so maybe that cost is passed along to us. Always remember, you get what you pay for... you save a few bucks buying an AMD GPU but you are sacrificing driver quality when you do.
This is why I quit using AMD GPUs. Sorry, but thats the choice AMD users are making when they open their wallet.
