I am having the exact same issue. i understand it may be a conflict between ms and fsuipc. but it 100% is not an issue without fsuipc. i realize fsuipc is asking a question, and ms is not giving an answer it likes, or none at all, but why does fsuipc continue to ask the question 65000 times in 5 min? and reverting to pre su12beta doesnt help. once this issue started, the only option is no fsuipc. im not here to complain, im just saying i have this issue, i understand its a beta, and i only use fsuipc for LRM currently so i can use the simconnect beta version of it. if you get the above errors in the console, clear it while the fps counter is up. you can watch as the errors keep climbing, the stutters start when the log is full and is clearing back down a few hundred and repeating that process. but when you clear the log the frames pop back and the errors start building again. without fsuipc, few errors, no buildup, and no stutters. if i can provide any other info, let me know. and i did not have this issue with the su12beta until i installed the new fsuipc. it worked fine, on whatever previous version of fsuipc i was using while in the beta, i jsut dont remember what ver i was on, and cant get old versions anyhow.
