We already discussed this on the GSX Creators channel on Discord and, the animation stuttering doesn't seem to be caused by the GSX update, it might just have happened coincidentally with some other update, possibly a Windows or a video drivers update.
To test this theory, we
HAVE posted TWO new OFFLINE installers to test:
Version 2.7.6 from last September:
https://app.box.com/s/hcjc7sx6uz8r5a3u1sq1jciqo0xllj2fA BETA version derived from the latest 2.8.2, with some optimizations to reduce the number of Simconnect calls:
https://app.box.com/s/ino7cuh2yql2zhm61o74y5lweq7c8xmaThe 2.7.6 version will downgrade the complete GSX code, including the sound that was the most important change and, as of today, everybody that tested it hasn't noticed any difference, indicating the stuttering hasn't been caused by the latest GSX Update.
The new BETA includes a bit of optimizations to reduce the number of simconnect calls in some animations (baggage loaders, mostly) and also in this case users who tested it didn't report any difference, indicating the problem is not too many simconnect calls made by GSX, so it really points out to something completely external to it, like a Windows update or a driver update.
