Do not turn off the rolling cache, people!

No mention of bing imagery in the setting’s description.

As it wasn’t an official “system requirement”, I can guarantee you that a lot of the issues users are facing on here are running this sim on a nearly-full HDD and not bothering to defrag their drive with every update.

That’s my case, but I tried with and without rolling cache and it had zero difference on performance. So just leave it ON.

I think I just punked you :slight_smile:

lol, actually through our ISP I can buy up to 2G now

I turned the rolling cache off today. My performance kept degrading after an hour+. Now it has been running fine for 3 hours. My rolling cache was set to 8GB as I had performance issues before with a 32GB cache. Cache management is not working very well in this game, might as well not waste the space on my fast SSD.

Similar experience for me today. Will test it again tomorrow on a longer period of time.

My download is around 200 Mbps and my ping in the vicinity of 8ms so np, that’s not the reason. Even at that speed, a hard disk is about 10 times faster.

Perhaps your disk is close to full ? In which case it’s not very good, especially with SSD. Their performance degrades when they are near full.

Myself, I would ‘die’ for speeds such as yours.
On a different note: I note that, as usual, your advice is good advice.

Regards.

I don’t agree. Rolling cache drops my frames by 5-10 regardless. Easy enough for me to test. Enable it, my frames drop and I get stuttering. Disable and it is gone and no more FPS degradation over long flights. Manual cache will increase performance but needs to be refreshed when new data is available. Rolling cache is simply to reduce your BW if you are on a capped data plan. In fact it can actually increase you data BW usage if you fly from different locations every time as it will need to populate the cache as you fly and load current scenery. Start from a different place next flight and the cache is useless and will need to repopulate the cache on the next load. Other than that it is completely optional and a user can decide if it is better for them to leave it on or off. Blanket statements like these declaring that one should not do this serve no purpose.

Rolling cache also increases the read/writes on your SSD which are finite. 32gb being overwritten or read probably multiple times in long airliner flights will certainly decrease the life over long term usage. Personally better the MS servers than my SSD.

I seriously doubt as popular as the sim is it even comes close to the power usage of server load in a week that Fortnite, WOW and COD put up in a day. I think if one is so worried about the environment and energy usage they probably should not use a high end gaming machine. On that note if we are talking about server load Facebook must be literally killing the planet and causing blackout everywhere. C’mon this is not even a valid point.

All of your statements you are presenting as facts and telling people to not do are in fact anecdotal opinion. You are dismissing others for stating what works for them saying it is “Not Scientific” but in fact your argument is simply just that, non scientific opinion.

While there may be no evidence leaving it off increases performance there is no proof that leaving it on increases it either. However, that being said we are all entitled to our opinion and as such can easily make our own decision.

Yes but a significant number of people fly at least a couple times in the same place. Some fly from a home base, some re-fly because they crashed, some restart with another plane, some play with OnAir or similar software and there is a home base, etc.

In fact it can actually increase you data BW usage if you fly from different locations every time as it will need to populate the cache as you fly and load current scenery

That sounds like a very dubious claim to make. I can’t see a single reason why you would DL more data with the rolling cache on than without. That doesn’t make much sense to me. If you fly in a new location, you will download the streaming data anyway.

I bet in Fortnite there is almost no load in data streaming, as compared to MSFS. All you have to stream is positions, actions and ammo speeds of the players. Same for COD. That can be done in a few kb per sec, as has been the case for every First Person Shooters around since Quake and the time when people ran on small data bandwidths. If that wasn’t the case, the game simply wouldn’t run as there would be constant desynchronizations. Even if there is 100 times more Fortnite players than MSFS players, this won’t match the hundreds of Mb streamed by MSFS in each flight.

But even without being specific on number,s is Facebook “killing the planet”? I’m not saying that, but they (and their users) indeed do consume many GWh of energy. But in MSFS, If we can avoid wasting energy, why shouldn’t we ?

So far, you are the one who seems to not understand how all of this works, but okay.

However, that being said we are all entitled to our opinion and as such can easily make our own decision.

Yes indeed. If you don’t want to turn the rolling cache ON, all the power to you. I just don’t think it’s a good idea, but your choice.

And many do not. Exactly why a blanket statement is not warranted.

I was being sarcastic. Calm down. Actually if you must know I am a network engineer specializing in VOIP and SAAS so I do understand the streaming aspects and how software is delivered over the internet.

Rolling cache simply stores the data from the AI generated data and a few other terrain related files. If you dont fly from point a to point B within the scope of your cache every time it is useless. To those that do, I’m sure it serves its purpose but it is not “necessary or required” for any reason other than BW saving.

Exactly my point. Thank you.

I have stutters and overall lower fps with roling cache turned on (100gb). Without it, it runs much smoother.

Thank you soooo much for all the comments about smoother experience while disabling Rolling Cache.. Before it was ok while starting the sim, departure… > 40FPS, after 1h when it comes to landing FPS went down to 15-20FPS. I tried to change everything I found… Graphic settings, Resolution, AI Traffic, MP etc. Nothing helped. Need to restart to have 40 FPS again. Now disabled Rolling Cache… had 2 flights and my first landing with 40 FPS, awesome :wink: Thanks Thanks Thanks. Will monitor if it remain - it was the only thing I changed now so my assumption is that turning rolling cache off did the trick.

Because I don’t like to have 15 FPS. If it works for you flawlessly fine… For me it seems to have a bug, don’t know why. As long this is/cannot be fixed I will leave rolling cache off.

It had 48 GB free (of 250 GB) with rolling cache enabled.

It was a bit lower when I had 32 GB rolling cache, only 24 GB free disk space at the time. The problem was when leaving detailed areas. It would run fine ish inside photogrammetry areas, after leaving the performance would tank for a long time. One flight I visited 3 PG areas in a row with the performance going further down after each one until I had to make an unscheduled stop to restart when my fps was down to about 2 after leaving the 3rd one behind. When I tried to exit the game ‘hang’ while doing stuff on disk. After 10 minutes I killed the process and deleted the cache since it was still busy. I guess organizing the cache, unresponsive, with disk access going up and down in the task manager.

With 8GB cache I still had big performance drops after leaving a PG area but it would recover after 10 to 15 minutes.

Without cache, no performance drops after leaving detailed areas, and no or rather less degrading performance over time. I suspect there is still a memory leak somewhere since eventually it will CTD if I fly long enough. The task manager says Flightsimulator ‘only’ has 7 GB in use, yet it also says my laptop currently has 32.7 GB comitted out of possible 42.2 GB, while the only other memory user is Firefox at 900 MB.

Long story short, it works better without cache.

To use cache or not to use cash? that is the questions. I personally prefer credit card as I get flyer points. (It’s all about flying you see).

We all like flying but I think the majority of us also likes to tinker with the sim. The incessant search for the holy grail of the best scenery, the most accurate plane, the nicest airport.
Sometimes things break yes, then we can vent here, blame xyz for all the ills in our sim or just take a break for an hour and start again.
I don’t know about you guys but I thoroughly enjoy this sim
cache or credit card..who cares…

Compromise:

When flying a A320 , keep it off. Does nothing.

When circling Venice in a A5, keep it on. Best of both worlds?

It’s best to keep it on even if you have a very fast connection like 1gbps, for the simple reason the Microsoft servers are typically slower than a decent SSD, on the other hand if you’re running the game from a hard drive there is no advantage and you may actually gain performance by keeping it off.

Thing is you say to have it on if you use a location more than once but if enough data gets stored between those flights, that stored data will have been overwritten unless you have a massive cache file.
I tried it back on last few days and haven’t seen any benefit whatsoever.
