Amnesia lags in the launcher and game menu

[Dave91]

I have ATI Radeon HD 4870 X2, and it works without any problems with this card so it should work with you as well.

Have you also updated your game?

Yes i have updated the game to the latest update. Grabbed it here from frictionalgames.com's site.
I've tried everything i could possible to figure out. Read the technical support and everything but it doesn't say anything about my problem so i don't know actually which is pretty sad
