I respectfully disagree that this is a hardware issue for several reasons
1. I have gone forwards in terms of specs, upgrading my CPU and RAM, while maintaining the same graphics settings as I did on my older hardware, and my experience with the 733 is worse now than before.
2. The above point is rather moot as I've found that this pause issue has only started after updating the plane to 1.2. Prior to this update I had a relatively pause-free experience.
3. This is the only aircraft where I experience this issue. Doing the same flights in the same weather conditions and same time of day with comparable aircraft in terms of systems depth and visual fidelity, I get no such pauses.
4. The pauses happen only when I start turning on systems in the 733. I haven't nailed down exactly when they start yet.
Ok So I went and started cold and dark and checked for the pauses after each step in getting the plane ready for flight, I got all the way through powering the plane on, starting APU, aligning IRS, entering and checking flight plan, through starting engines. Up to this point I have no pauses. The next step for me is transferring power from the APU to engine generators, setting the pressurization, turn on yaw damper, turn on window and probe heat, and turn on engine bleeds. Somewhere in that process the pauses began. I then reversed all the steps I did to see if the stutters would stop, they did not. Perhaps they just happen to start at a particular point in time and are not dependent on an action I'm performing in the cockpit. I have attached my X-Plane log as well as my Gizmo log. Hopefully this will help.
