I'm not sure how to describe what is happening but here goes.  I'm using the boxed version of FSX.  I have a lot of ORBX scenery and fly Carenado aircraft.  Here is my configuration.  Intel i5 4590, EGVA GTX 1070 latest driver, 16GB Ram, Samsung 250 GB 850 EVO SSD, Windows 10x64, FSX,Orbx FTX Global Base, FTX Global Vector, FTX Terrain, Northern & Southern CA, Pacific NW, Rex Texture direct + Soft Clouds.  What i'm curious about is several times during my flights FSX seems to reload.  It only takes about one second.  It's the same screen as when you press the button to fly and it's loading but it can't be for more than 1 second and then it continues where it left off.  I'm sure it's a memory problem but don't know how to fix it other than moving the scenery sliders to the left.  Is this an accurate summary of the situation and is there any suggestions as to how to fix the problem.  Really, it's kind of annoying but on the other hand it does reload and go on. I'm pretty sure my RAM is maxed out.  I have just endured it, but wondering if anyone can give me some suggestions on how to fix it.  

If you have a registered version of FSUIPC, the sync to real time option may be checked On.  I'll even

give credit to Jim Skorna because I copied this from a 2102 post of his!

Actually I do.  I'll check that.  Thanks

charliearon, just wanted to say I just flew a 1 hour flight after unchecking the real time option in fsuipc.  No problems whatsoever.  So I believe you just solved my problem.  Thank you kindly sir.

I was about to set my FSUIPC to sync FSX to real time when I read this thread. I think I'll give that a miss now!
