Just upgraded to version 11.8 a week ago and in my case the new driver brings a positive result — places where used to have stutters now become smoother even though no obvious increase in overall fps.
Two major changes in setting I use in the new driver are the enabling of 64X Tessellation and Surface Format Optimization. Both of them were causing some degrees of performance degradation. Click here to see my earlier 11.7 setting.
Due to the discrepancy to what I’ve been using for a long time, I am now re-tuning my whole system as if it was just newly installed. Will post the whole process and the final results and settings when done.
