After 1.4, I could get rid of the stutter by turning the nameplate scaling off. After 1.4.0b, that no longer helped, however the stuttering was relatively minor. So I went through the abovementioned steps, and now the stuttering is 200%-300% worse, combined with small framerate loss, which in result makes the game unplayable.
My graphic card is ATI Radeon HD 5700.
doing these steps will not make it worse ... try the steps again launching the game after every time to see what makes the biggist affect
