Earlier this week we published benchmarks of the XRender extension using NVIDIA's latest beta Linux driver, which had a substantial performance boost thanks to Render improvements with this latest driver. One of the questions that have since come up is how ATI/AMD's binary Linux driver compares when using this X extension. Well, right now, it lags behind NVIDIA, but a Phoronix Forums member has discovered a hidden ATI Linux option that should yield XRender erformance gains.
