Hello Yapa, and welcome to the forum.

Micro stuttering is a problem of graphics cards or graphics solutions with more than one GPU. The basic idea is that the GPUs calculate the individual frames in turns and thus each GPU would have to calculate a lower number of frames. You can think of it like this: GPU 1 delivers the first frame and 5 milliseconds later GPU 2 delivers the second frame. After an additional 5 milliseconds GPU 1 delivers the third frame and so on. Unfortunately it happens that the output of the GPUs is not synchronized and the pattern changes as follows: GPU 1 delivers frame 1. 8 milliseconds later GPU 2 delivers the second frame and 2 milliseconds after that, GPU 1 delivers the third frame. The framerate would still be the same as in the first example but some people experience the irregular frame output as stuttering. Since this is not the same as normal stuttering, which is caused because the graphics card is not powerful enough, the two versions of stuttering are differentiated by calling the multi GPU problem micro stuttering.

I hope this rough explanation was helpful. (The times I used for my examples don’t match the real time graphics cards usually need to calculate a frame. I just used any numbers to explain the problem.)

Stalker Clear Sky is not the only game that suffers from micro stuttering, since the problem is caused by the multi GPU solutions and not everybody recognizes it. We already experienced micro stuttering in several games. The most popular ones are Crysis, Unreal Tournament 3 and Call of Duty: Modern Warfare.

I dont actually know what micro stuttering is? Can you explain more about it?

Is it the very small 'stutter' as you move around screen? And is it only visible on SLI/multi gpu solutions?

I have never noticed it... why does Stalker CS have it and other games do not etc?

Anyway to see the print article on the web?
