I have to confess. I have been a n00b and went for a Crossfire setup. The worst decision I've made with PCs. Micro-stuttering is a b*tch. Thought it won't affect me. But no, everybody falls into the same trap. Reviewers should do a better job than just showing the FPS count, and showing the apparent FPS by whatever calculation necessary. I am pretty much only playing BF3 (MP - 32, 48 or 60 players ) these days. Whenever I am going below 60fps, micro-stuttering becomes noticeable. Afterburner is saying it is at high 50's, but it feels like 25fps. I am a sniper, and it makes my head ache when I try to focus on a target (when fps drops below 60fps that is) Micro-stuttering is there, and there is no way to triumph it. But why does it dip below 60fps? These cards are unlocked, albeit only having 1GB of frame buffer per card. I know, 1GB might not be enough for BF3, but still... Most of the times when the framerate is low, afterburner is showing bad GPU utilization on each or second card. When it is above 90%, it is silky smooth, not because it gets rid of micro-stuttering, but because the FPS is so high that the effect of micro-stuttering goes unnoticed. Does anyone know why the GPU utilization drops below 90%? It can go as high as 98% on both cards at one instance. I was playing a MP game few minutes ago and the utilization dropped down to 50% on each card and it was stuttering as HELL! I am using 12.3 drivers with cap1. tried 12.1 and 12.2 with caps and all and it is still behaving the same. 11.12 wasn't this bad. perhaps i should go back to it and see?
