Hello Pete,
hello community,
I also have this stuttering issue with FSUIPC which has been mentioned here several times before. I am using an unregistered copy of FSUIPC 3.998n with FS9.1 on my PC (Intel i7-2600, 4 GB RAM, ASUS P8P67 MB, EVGA 560TI, Windows 7 Prof. 64 Bit).
Since I updated my system two years ago I am experiencing stutters with certain aircrafts and was therefore so frustrated that I finished using Flight Simulator. Nevertheless, from time to time I tried to find the solution and it seems that I finally found the (root) cause.
Recently I installed a pure FS 9 version. Locked at 30 FPS (my screen is using 60 Hz) and performed some taxiing on the ground (low graphic settings, using the default Cessna R172 and the default B737). Everything is smooth.
Now I installed the FS 9.1 update. Again, smooth.
The next one to be installed was the actual FSUIPC version and experienced a very unsmooth sequence of frames (stuttering). I went back and deleted all FSUIPC related files which resulted in a very smooth taxiing again. A following installation of FSUIPC brought me back the heavy stutters.
The crazy about that is that it only affects the B737 and not the Cessna (I don’t know yet whether other default planes are affected). Also planes like the PMDG 737NG or PMDG 747-700 are hit. Additionally, I noticed locking fps at 60 eliminates the stuttering. But unfortunately this is no option for me because my machine is not able to keep the 60 FPS at any situation.
What is going on there? I also added the brief fsuipc.log file.
Hopefully, you can give me back my hobby :razz:
Thanks in advance……
Best regards,
Tobias
