Sluggish performance with nvidia 185.18.14
I've been using the nvidia 180.60 driver and the performance is amazing: silky smooth window dragging and fast, fluid rotation of Compiz's cube. When I attempted to upgrade to the latest nvidia driver, 185.18.14, however, window dragging became sluggish (with tearing) and the cube rotation is abysmal. I'm not sure if there's a setting in my xorg.conf that is deprecated or what gives!?!? I'm anxious to check out some of the new features in the 185.x.x series drivers but I don't want to give up the great performance I experience with the 180.60 driver. I'm running Ubuntu 9.04 amd64 with an nvidia 9400 GT (512 MB DDR2 RAM onboard...see my signature for the rest of my hardware.) I would appreciate any help in resolving this problem. I hear the 190.x.x series drivers are right around the corner and I fear performance will be degraded with those as well. Below is a copy of my xorg.conf:
