new problem after patch. Sometimes I have blur for 1-2 sec. It can appear any time. ANd I made user.cfg with 

WorldRender.MotionBlurEnable 0
WorldRender.MotionBlurFixedShutterTime 0
WorldRender.MotionBlurForceOn 0
WorldRender.MotionBlurMax 0
WorldRender.MotionBlurMaxSampleCount 0
WorldRender.MotionBlurQuality 0

But It didnt help
