Hello Everyone, Before I start, I have been an FSX simmer for 10+ years now and I know that fsx can be very simple or very complex depending on a number of different variables. I also know that it is virtually unheard of for any flight simulator rig to have NO stuttering whatsoever. I am posting this thread because I have tried everything I know and have made NO progress with my recent plague of stuttering in FSX so, here goes. A few months ago, I started experiencing a VERY noticeable stutter (precisely once per second) while at one of my Flightbeam airports (KSFO) so I discontinued the flight and started troubleshooting. This stutter was NEVER there before and my sim ran like a dream to me. I researched, googled and tried many different "tricks" to try to resolve this issue. Below is a list of things I know how to do and have done without success: 1. config file tweaks (AFFINITYMASK, BUFFERPOOLS,etc.) 2. delete config file and start from scratch 3. uninstall all addons one by one 4. reformat whole computer (reformatted and did fresh windows install, reformatted FSX drive and reinstalled everything on a like new machine) 5. uninstall, completely clean computer of FSX and reinstalled fsx and all addons 6. Downloaded and installed all new drivers for GPU I understand framerate drops and dips and bounces around if you don't have it locked, but it is locked at 30fps. I have absolutely NO framerate issues (smooth as can be) but once per second, it stutters terribly. even at higher altitudes when there is not as much scenery to load. I will describe my system below and hopefully someone can think of what I'm obviously missing. Gigabyte Z77HD3 MoBo, Intel Core i7 3770k @ 4.5 Ghz, EVGA Geforce 660, Coolermaster closed loop liquid cooler w/ 240mm radiator, corsair vengeance ram (16Gb), 2x Samsung 840 EVO SSD (120 Gb for Win 7 and 250 Gb for FSX only). With this rig, I don't see why I would be having lagging or stuttering. As I said before, it seemed to have started abruptly and to me it seems like something is running in the background. Any help would be greatly appreciated. Thanks in advance.
