Hi,RC and Txt display are the only 2 programs running on a client PC (Windows XP - 1.9 Ghz) connected with FS through a registered Wideclient/Wideserver v6.75.Most of the time there is a big delay and upon checking it appears the CPU usage of the client PC is practically always 100 %.Take it this is not normal. Is there any remedy ?Kind regardsTony

what processes are running, that are eating up the cpu?what version of rc?xp sp2? xp sp3?

Over 90 percent is taken by Wideclient.RC 4.1XP SP2I have five more PC's running with the same Wideclient/Wideserver v6,75 and not one has problems with high CPU use.

send me an email, and i'll send you a link to download 4.3let's see if that makes a difference.there never was a 4.1, only 4.0, 4.01, 4.2 and 4.3, so i wonder what you havejd

Actually it is 4.01 (v 4.0.3737 is shown)Will email you.Thx and regards

I'm seeing exactly the same! I purchased Radar Contact about a week ago, and I've been wondering about the very sluggish performance. RC 4.3 is running on a laptop with Wideclient, FSX and latest version of FSUIPC at the other end. Before launching radar contact CPU usage is 10-20% (Active Sky X is running), but a few seconds after connecting RC, CPU usage jumps to 100% and stays there. From the process list I can see Wideclient using between 80% and 95%.Disconnecting RC drops Wideclient CPU usage back to just 1%.Can you suggest a fix this? Otherwise I think I will have to reinstall RC on my FSX computer.Tom

OK Tom, we may assume that there basicly is something wrong irrespective of software version.May I make a few more observations abt my setup : Monitoring the Wideclient CPU-use during flight I noticed that :- just the connection between RC and FS shows a 100 % usage- when there is an action in RC (e.g. heading call) the usage drops ;- when FS is paused the usage drops considerably ;Adding extra memory to the PC does not change anything .RC works, but the high CPU load too often causes big delay in reponse time and leads to skipping / mixing up some calls.Hope JD can find the remedy.Tony

i don't use widefs, so i can't troubleshoot or speculate on the cause. half of the beta testers do use widefs, so i've shot them an email about this threadjd

pete has a thread going on his forum regarding this issuehttp://forums.simflight.com/viewtopic.php?...2b0b9783c785389jd

Hi JD,Pete has made a special Wideclient version as you may have read in the meantime.It appears to work OK and does not devorate the whole CPU capacity.Thanks for your helpKind regardsTony
