Hope next driver will close the problem with Space Marine multiplayer game microlags. I tryed to return on 306.23 and found that there's no microlags there. There is 1 great lag which last 1-2 min and appears only on 1 map - Basilica(on other map game runs fine, like with AMD GPU). http://www.youtube.com/watch?v=y0SW7R_usec - for example, this game lags 2 min then runs fine (driver 306.23). With newer drivers(and 320.18 too) lags appears many times and lasts 1-4 seconds. But appears randomly on all game maps. It's sad. I realy liked this game with 6950. Hope u fix it soon.
