Radeon HD 4870 X2 resolves micro-stuttering
Microstuttering is a result from using AFR (Alternate Frame Rendering). The frames are then sent to the monitor at an uneven rate (more like two and two instead of a steady flow) which causes stuttering. Running two Radeon HD 4870X2 in CrossFireX for three or four GPUs should still have the same rendering problems though, I.e. if AMD hasn’t come with another new feature for the Radeon HD 4000 series, but we’re skeptical there.
