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....

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

OK, great, many thanks ! Will check. If SimConnect is failing, how to correct ? is there any stand alone installation for that ? many thanks ! JM

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

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
