maca11 Posted June 23, 2014 Report Posted June 23, 2014 Dear all, I am using p3d v2.2. and FSUIPC (latest version). After some testing I believe I found p3d setting which is quite efficient. It flies cca 15 FPS neat heavy airport and 30+ FPS otherwise - smooth. However one issue looks strange. Every 2-3 minutes of smooth flight (altitude above 22000ft) all suddenly slows down from 30+ FPS to 5-7 FPS. This takes about 10 seconds and then gets back to normal. This occurs all the flight every 2-3 minutes. Initially I thought it is about weather injections (from REX) but after some testing it looks it has nothing to do with weather. (even REX not running, p3d set up for clear sky and no updates results are absolutely the same...). I tried everything but the situation is the same..... every 2-3 mins some slow down and back. Looks like it is checking or dowloading something. So my last thinking was if there is not any tool or parameter in FSUIPC which tries to check or download anything which is causing this stutter ? Is this a false way of further investigation or any other idea ?? many thanks ! JM

Did you enable FSUIPC's autosave option, to save flights at 3 minute intervals, or similar? It is possible for that to cause a stutter if there's a lot to save, as with some add-on aircraft, though for all normal use it shouldn't be noticeable at all. I have mine set to 3 minutes and never notice the tiniest stutter, but I know folks using PMDG aircraft, especially, have this problem as the PMDG aircraft flight saving stops everything whilst it collects all the subsystems data, so they are all synchronised on reload. If you are getting it with default aircraft I can only think your disk is very full and your Windows caching is off or for some reason unable to get enough memory. Pete
maca11 Posted June 23, 2014 Author Report Posted June 23, 2014 Many thanks for reaction and some more tips.. Actually all in FSUIPC seems to be unchecked.... No autosave. In wind section of FSUIPC I unchecked everything, only which remains is 'weather input check (1-30)' - 1 often, 30 very unregularly... I cannot put there 0, however, whatever value I put there the result is the same....2-3 mins sudden slow-down... JM

No, the weather reading cannot be responsible for any delays, and that's a very regular action in any case, up to frame rate repeating, same as most of the other data obtained through SimConnect.. From what you say I really don't think it is FSUIPC giving you the problem. There's nothing at such intervals -- the only possibility was the autosave. Check the FSUIPC4 log, a text file in the Modules folder. Maybe the SimConnect installation is failing and the delay is caused by a regular attempt to reconnect. The log will show such attempts. Otherwise I can only suggest you ask for advice in the P3D forum over on AVSIM, or at L-M. Pete
maca11 Posted June 23, 2014 Author Report Posted June 23, 2014 OK, great, many thanks ! Will check. If SimConnect is failing, how to correct ? is there any stand alone installation for that ? many thanks ! JM
Pete Dowson Posted June 23, 2014 Report Posted June 23, 2014 OK, great, many thanks ! Will check. If SimConnect is failing, how to correct ? is there any stand alone installation for that ? The are FSX SimConnect.msi files which can be used to install usable modules. With P3D you shouldn't need to -- it may be a re-install job. Best to show me your log file first. In fact if you can find the FSUIPC4 Install log as well as the FSUIPC4 log file, both in the Modules folder, show me both -- paste them into a message here. You can use the <> button above the edit area to quote them as a text file. Pryr
maca11 Posted June 26, 2014 Author Report Posted June 26, 2014 Many thanks for all the support. After further testing it looks it is not FSUIPC or simconnect. It is about heating of GPU (once it reaches certain temperature it slows down for few seconds FPS andf then gets back...). SO i need to find out why is that... JM

How did you identify it as the GPU? I have an older PC which does something similar sometimes. I always assumed it was down to all the other processes and services I have running on it -- it's my general use "dogsbody" PC! ;-) Pete
maca11 Posted June 27, 2014 Author Report Posted June 27, 2014 I realised that always around the time of slow down the graphic card fan works more intensively... So I run NVIDIA inspector and saw that in these intervals (2-3 minues) temperature goes up to 96C and in that situation system cuts power and slow down GPU, in 10 seconds it gets back......... Do not know what to do with that but thats the situation....

I am actually suspecting the fan on mine in any case -- it sounds decidedly odd. Pete
