Try closing background programmes as well as turning AA off, dynamic shading off and lower resolution. It may improve your PC performance. Moreover reconsider changing GFX card for something newer.
Death of Foltest was necessary for the plot. But fear not there are still many surprises and adventures waiting for you in TW2. His death could be deducted from TW1 but I will say no more:)
Damn I have reached my quota of "minuses". You certainly would get one.
Multiplayer doesnt means downgrade of single player content. Introducing multiplayer modes isnt joining MMo market. there are plenty of diffrent modes like survival or CO-op that requires multiplayer!
Too bad 227 that you have no faith in studio. Multiplayer makes your adventure in game last longer. Iam sure RED Studio will create breathtaking gameplay which will fully satisfy you for dozens of hours.
