I don’t understand what’s going on though fortunately i am getting no issues on recent 3 flights, first time since these 2 or 3 weeks…
Finally i am ready for PMDG
I don’t think i have changed settings…
What I noticed though was every time i was having issue was one core use of CPU is maxed out when I check task manager even in mid air, external view, where usually core usage is less than 50% in my rig&setting.
I also have this exact issue. It’s happened twice on long hauls. FPS drop to 1-5fps and completely unplayable. Most recently on a long haul from VHHH-KMEM, it was fine until I started to pass over Kansas area.
When it occurs, various limited by mainthread issues, low GPU usage/temperature. Virtualisation disabled.
My specs are a 5900X, 2080 super and 32GB of RAM. Sim runs fine, usually.
Well if you havent changed anything since then, you have to look to the things on the end you cant control. ie. The server your connected to, the network path to that server etc. I have the same issue sometimes I can fly for hours on end no problems and other times (last night) 20 min in and we’re running in single digits.
From Dec 26th up to about two weeks ago, I had those big fpm drops beginning after around 40 mins. (60 fpm down to around 5fpm over a period of an hour approx.
I tried every possible combination of settings, on-line, off-line, weather off, weather on, full-frame, windowed mode, rolling cache, no rolling cache, and so on… all to no avail.
My issue disappeared without any input from me, or any hardware changes, so I have to believe this whole fps debacle is completely external from our PCs or internet connections and I’d guess we’ll have to just wait till Asobo or Microsoft figure out the cause and rectify it. It’s a real shame, seeing as the sim is otherwise so good.
Its funny because this morning I flew a 1 hour flight and everything was perfect. An hour later launced again, and my fps is up but my LOD is missing. It displays to about 20 mi out then its just flat blank nothing. Even little mountain was missing again.
watching the network both times (yuck back in debug mode) and the network performance from what I can tell using ping plotter window performance monitor etc, to be identical. So that for me at least is starting to narrow it down to server issues.
Maybe theres a cyber attack going on that no ones yakin about. I know back when this first came out I would see articles related to azure and the server farms. I know that one of the articles said that the failure rate in the farms is extremely high, so who knows maybe they just burnt up a bunch of servers again, and MSFS was on some of them.
Just counting the days till either the end of the world or that other products beta comes out! ROFL?
This also started for me a couple of weeks ago since the Australia WU. It seems to happen more in the FBW. I’ve tried a clean install of the sim and FBW which helped a little, but I’m still getting the degradation of FPS after about 30 mins. My sim on the same settings runs no where near the usual 40-50 fps I used to get before Christmas. I’m at a loss as I’ve changed nothing my end hardware wise. My issues all started around the WU and when I had an Nvidia driver issue mid December causing CTD. other than that I’ve had a flawless sim since day one until the last few weeks.
Not sure if this is of any help to you guys, but this just solved all my issues i think. Testing as we speak. I had my monitor in 144hz and geforce settings wernt correct. Heres the link to what helpled me. Now got a solid smooth 30fps locked atm, gpu is now working as it should. Ill test and let you all know if i get any performance drop in the FBW as i normally did. Reproducing yesterdays flight where i landed with only 5fps.
After testing for an hour it seems it has degraded slightly, but not as bad as previous flights. I have noticed this though in my monitoring. My standby memory went from only 4000mb to using everything, and thats where its started to degrade. Im not 100% sure this has anything to do with it as im not a big techy, but thought id post it up in case someone who knows what it might mean, if anything at all.
Just ran a flight 6 -720 am edt. I started getting your bandwidth is to low we will continue to reconnect you, click ok, then I reconnect. On another couple of mins and same thing, over and over again. Popped up win/perf and Im sending data but not receiving anything back from the server.
Hit reconnect, and it just sits there for 10 min, finanly telling me I dont have the bandwidth and it switched me back off line again.
Kill the sim , check the net with pp and the bb test and all is normal. So what the hell is going on now.
When I said I wanted consistency I didnt mean constantly bad. geez come on already!
I’m trying to reproduce this issue now through pure curiosity, 2hrs 15minutes into a flight (about halfway through) and my GPU usage has just dropped from the low 90s% to mid 70s% for no apparent reason. FPS has gone from 80s to mid 70s, I have no mods installed.
I could confirm that, too.
When standby eats up everything and free gets zero, fps got worse and having stutter…
I didn’t expect 32G RAM is not enough…(?)
I have changed ndu as well, tried 3.5hrs flight and I think somehow it is way better than before, still having bit fps drop on arrival handcrafted airport (OMDB) w/ no “free space”, it was really nice experience.
