I guess this is just one more to add to the list of all the previously reported “Memory leaks”, but this one is easily demonstrated, so here goes.
It became very obvious on my current Trans Atlantic flight in the C172 at Mach 2.5
Hold on … bear with me !!! (got your interest though – Mach 2,5 in a C(oncord) 172
Set the sim to x16 and flew the C172 from USA to UK.
Monitoring the memory use, now in x16 time, one could clearly see the memory use increasing, the CPU thread time increasing, and the FPS dropping.
I realize this is an ARTIFICIAL mode to be running the sim in, but it does speed up the leakage, so it becomes very obvious.
SO effectively, its a 24 hour flight in about 1.5 hours.
While very few run the sim for 24 hours +, it does show the leakage,
I Have 32 GB of ram, if I only had 16, I would have run out of memory about 4-5 hours of flying in Real time.
Just approaching the Irish Coastline, and my memory usage is up to 24G out of 32G.
Will resume this post when I land, and I suspect I will not see that memory recovered.
I wonder where it is ??? Lost somewhere over the Atlantic ??
Its not like over the Atlantic, it was being used up collecting "SCENERY’ !!!
Well, did not make it to he UK… PC locked up, LNM had a fit first, and all I could do with the locked screen is to log out…
Maybe try again another day without LNM running, but it was the MSFS developer’s FPS tool, that was reporting MSFS high memory usage…
Tip: If you want to try this, when AP is on, you can only increase sim rate to x4.
Trick is to turn AP OFF, increase sim rate to x16 or higher, and then turn AP back on.
AP will drop sim rate down to x16, but that is much better than the minimal increase to x4 you can get with AP on.
