I see everyone else is rejoicing in how great the game now runs but for me it is worse. When near the ground, the game is like 9FPS 1440p no settings changed, CPU load is only 50%. Then suddenly the load jumps and it runs smooth. I used to have to use process lasso back in the day before the Japan update, which made it unnecessary, but now I may have to try it again. Anyone else?

Well.

I've mostly used the FBW mod of the A320 lately, so I don't know if that is the explanation but I have, since update, noticed an odd phenomenon: When flying sometimes the frames drop precipitously making panning around in the cockpit a real chore. The computer in itself doesn't seem to get sluggish as going to another window everything is snappy and fine. This issue with FPS can continue for maybe 30s to one minute and then resolve itself giving me smooth experience again. Never see this before and I see no rhyme or reason with it (it can happen over rural areas where I generally have stupendously good performance). I was kind of suspecting the terrain streaming but who knows..?

Hi

Ive seen this happening since the update. I noticed it seems to occur when flying through high clouds at 30-40,000 ft most often - frames drop outside but in the cockpit itself is still relatively ok.

I read somewhere that Asobo had made some changes in their cloud modelling- there are definitely more cirrus level clouds than I had been aware of before. They also said they’d noticed frame rate drops outside when flying through them.

this definitely happened to me flying through high clouds over huge thunderstorms in PNG and Queensland this week.

Anyone else noticed this?

It's happening a lot in the UK since the update.  I'm flying along at 50-60fps when suddenly, the sim stutters and drops down into the 20s then goes bsck up.  Feels like a scenery loading issue.

The odd thing for me is that when the "frame dips" occur, weather doesn't seem to affect it. Most often I've gotten this while flying in glorious weather over very sparse terrain.

Do you guys use an external frame limiter? I used RTTS and had bad performance after the latest update.

ASOBO aparently improved internal VSYNC and I have to say that it works on my end (dropped the ext limiter)

I have never flown over the UK yet, but I feel you are on to something and have been suspecting the scenery streaming.

If I limit FPS it's from within the sim, however this is happening with and without frame limiting.

I have been watching my FPS constantly (for about 2 months now) with the inbuild Developer mode and also with RTTS. I can't say it has been getting better or worse. The only thing I noticed with the latest update is screen tearing which came from RTTS.

I fly over Germany and Austria most of the time (so not over crowded scenery stuff...)

I have noticed the same, not just the UK, it's happening everywhere for me. I can be flying along, and suddenly drop form the usual 50 fps to as low as 16-19fps... and then as soon as it happens it's gone again...there seems no pattern to it (It's occuring anywhere i fly) I have checked the usual Internet connection (solid 60mbps)the usual rolling cache... it makes no difference... it certainly seesm like an issue since the last update.

I have had the rolling cache off since the update.  Maybe trying it again might help.

I am getting it too with the rolling cache on.  In the upper 50's than drops to 20's for 20 secs or so...and then back up. Clear or clouds, low or high alt.  Near cities or not.   I can deal with it, only happened once on approach, which was not that great 😁

 With last update, made some changes that for me were perfect. On nvidia control panel switched low latency to ultra, and blocked refresh to 60 hz ( was at 165hz). The resolution is 2K (GSYNC compatible, but not certified). Then started MSFS, went to config and switch on VSYNC on and limit fps at 30. Now I have all my sliders to ULTRA 😀, and it stays steady at 30 fps. When flying on cities like London or New York, just need do reduce do 80% render scaling to maintain the 30 fps. My cpu is old, and maybe we was always trying to reach the maximum frames, and produced a lot of stutter,and since I decided to limit frames went from main thread bound to Gpu bound. Now I can drink all the juice my 2070 super can give, with stuttering free. Is a big difference for me. You can see my specs on signature. 

 

If it is related to scenery downloading, I wonder if the US servers are faster than Northern Europe?

I had performance issues during last two updates, I deleted rolling cache and also graphics settings and set everything from scratch and it did help on my 8 years old PC, I’m happy with current state of Sim which will eventually continue to improve,
