First, commonly people don’t keep PCs cleared of clutter as they should.Just for giggles, try clearing your Shader Cache first. If no joy try the tweaks in the link below. One at a time until you hopefully hit gold. Which also tells you how to clear Shader Cache.https://bbs.hitechcreations.com/smf/index.php/topic,412969.msg5477540.html#msg5477540
Before the official update after d/l the test patch I experienced zero cyclic stutters... I changed zero settingsSince the official patch ran, I've experienced increased micro-stutters that are not quite cyclic, but have produced that same split second netstat spike and frame drop.I went and tweaked that nvidia shader cache to unlimited - doesn't do anything helpful.I'm also noticing more small jaggies in the host queue graph, where in the past it was fairly flatlined.<shrug>
