Author: Chris Wilson <ch...@chris-wilson.co.uk> Date: Wed Feb 23 23:09:36 2011 +0000 intel: gen3 is particular sensitive to batch size ... and prefers a small batch whereas gen4+ prefer a large batch to carry more state. Tuning using openarena/padman indicate that a batch size of just 4096 is best for those cases.
