Hello. I suddently have a problem with RCv4. I did a fresh reinstall of both FSX and RC and when using RC i have strange stutters. It's not common and well known microstutters within FSX but as soon as first RC wav is played - usually ATIS - the FSX start to stutter, which looks like the picture got still and from this "photograph" new FSX graphic raises, if you know what I meanHow to describe it better - imagine still picture and while it is supposed to change as what you see changes, it doesn't and stays on screen for a fragment of second, which happens every few seconds. I hope I describe it well. If not, I will make a video.Without RC playing wavs my FSX is pretty fluid running at 30 fps limited externally by Nvidia Inspector.Strange is that with previous installation of FSX and RC everything was running perfectly.I tried to use newest FSUIPC, my RC is on a different hard drive than FSX, I have external USB sound card. Autologging feature of FSUIPC is disabled, I did some research here in the forum, found few with the same problem but no solution.Any help please?Thank you.

RC options for best performance:Display.txt = offPrerecorded AI Chatter = OffInteract with AI = OnAI Chatter = OnThe rest are system performance issues. RC does a lot of disk access to collect and combine .wav files for ATIS and CD to buffer in RAM the entire audio feed for playing.If this is occurring at an airport area your ai can take a heavy load on the CPU since the CPU for FS9 and FSX is used for most of the model rendering processing.If you are an ASE user be sure you have the latest service packs installed along with FSUIPC from:http://forum.simflight.com/topic/66139-updated-modules/Shut down any not required processes running in the background.

all of a sudden you have this stuttering? unless something in rc has changed, then it's probably something else you did to your machine. new driver. new antivirus, new something, somewhere. think about when did it start, and then look and see what was installed around that time.and you can send me a log, i'll take a look and see if there is anything there. info pinned at the top of the forum. duplicate the problem, and send me the log file, zipped.jd

Thank you for your suggestions, great customer support.Finally it turned out it had been some sort of graphic problem, which I solved within fsx.cfg by settin poolsize=0.I don't know how can RC be connected to graphics, but it did the trick.
