Brief description of the issue:
My sim is stuttering on approach at airports. I never had this issue until I upgraded to the 3080 ti. I have turned off rolling cache completely and still having the issue…
Provide Screenshot(s)/video(s) of the issue encountered:
Detail steps to reproduce the issue encountered:
Approach any airport.
PC specs and/or peripheral set up of relevant:
i9-10850K, 3080 TI, 32 GB RAM.
Build Version # when you first started experiencing this issue:
First check whether your hardware configuration is reasonable! Check whether the system is updated to the new version! It is recommended to download the game ontology again.
Is there a way to completely remove the game without having anything left over for a fresh install? Because every YouTube video I’ve seen says no matter what certain folders stay behind.
Are you perhaps becoming main thread limited? worth checking to see if you are. There are numerous threads on this forum about this issue. The graphics card may need to be loaded/utilised more than it presently is. It may be sitting there screaming for more data and the CPU is struggling to feed it enough fast enough causing 100% mainthread & subsequent stutters. Turn down the settings that keep the CPU busy and turn up settings that keep the GPU busy. eg. Have you tried upping the render scale? beyond your output resolution it will keep your GPU busier and not so demanding of the CPU.
As Brag says, increase gpu load … and you might also try the public hotfix beta, it goes a long way to eliminating stutters … when released it will definitely be a nice Christmas present for those that struggle.
I’m pretty sure latency ultra limits the gpu to rendering one frame at a time instead of queuing them so I’m wary about using it. Maybe you can share your experiences. Does it increase fps or quality or limit stuttering? I couldn’t tell when I tried it.
Why would I now be cpu limited when I upgraded from a 1070 to 3080 ti with the same CPU? That doesn’t make any sense to me. I mean technology is super weird though. And how exactly do I make myself more GPU limited… I don’t really understand that.
You bought a super fast top of the range GPU. FS uses a single thread of your CPU to run FS. Your new GPU is hungry for data. You CPU is working hard to supply it that data, so much so it becomes mainthread limited. (Check CPU load with tools). To throttle back CPU usage, load the GPU up more so it is not waiting on the CPU for data as much. The easiest way to do this (assuming you have already switched most settings to Ultra already) is to increase render scaling beyond what you think you need. This keeps the GPU busier and balances CPU load out more. At least this is what I have read about the issue. Just search the forums here for a more technical explanaion of CPU main thread limited and stuttering. Also try reducing LOD’s(TLOD & OLOD) down from >200 as they can affect CPU load too. (again from what I’ve read elsewhere on this forum)
I think many people just move all sliders to the right without thinking of the CPU load consequences. Yes I’ve read those threads and it makes perfect sense (as do your settings) to me.
Yes low latency limits frames to 1. In my case Ultra reduces stuttering more than On. Low latency is an old approach mitigation when the GPU is pushed to its limits, so that CPU can help a bit with FPS, but with a tank like the 3080Ti you don´t need to care about GPU being pushed to its limits. It will work at 100% performance most of the time and indeed the CPU will be the one limiting it, so you better release CPU workload instead. Indeed I never had substantial increases in FPS during years when I used those kind of tricks involving queued frames with Nvidia cards. Maybe you can gain 2-3 fps in some specific situations but I think this is just a patch when your system is pushed to its limits.
The real problem is that HW accelerated GPU scheduling is not intended for high end computers and it creates more problems that benefits, specially stuttering. That´s why everyone is recommending to disable that. Game mode does not make any real difference at all, so I prefer to disable it as well.
The frame rate killers (in addition to AI traffic) are: clouds at ultra (specially together with terrain shadows at 2048) and terrain viewdistance (above 200 performance decreases). The rest you can leave them at maxed settings.
I have a similar setup as yours (i9 9900k in my case) and I run at 1080p + 200% scaling cause my monitor is not 4K. Just by the settings I told you and lowering the clouds to high I have no problems with stuttering and can stay in the 40-50fps range most of the time. At really populated airports with lots of AI planes I could get as low as 30-35fps in the worse case, but this will be most likely solved once we have a true DX12 support that releases some load on the CPU, which is the current real game bottleneck no mater which NASA CPU you use. For the time being use AI optimized models to prevent this.
EDIT: very very important in case of multimonitors setup → always make sure your mouse is focused on the game window (click on it till you see the game´s mouse shape) as for some reason this can make you lose up to 10 fps in game. So, if you are playing around with a moving map tool or whatever application or window on your second monitor remember to go back to game and click anywhere on game window.
I’m GPU limited right now so CPU sits at 35%, GPU at 100% most of the time with FS. If I manage to get my PC upgraded at some point I’m all set in my head with what settings I’ll use.
Yeah I am GPU limited now aswell which I think is the way to go! With flightsime you can afford to play at 30fps. The CPU stutters are a nuisance so I prefer to be GPU limited (3070ti) I get the odd spike of main thread limited at EGKK or KJFK for example but much better this way I agree.
