Low cpu/gpu Usage

[Msgt.Dingleberry]

I assume everyone is having this issue. I have a 2080ti and an overclocked 8700k. The simulator is averaging about 20% usage from both components. I can barely get 10 frames. THe game is absolutely unplayable. I installed the new geforce drivers, I think it helped a small bit with stuttering but the frames are still horrible. I haven't found any other fixes yet, guess we just wait for Microsoft to fix it.

so iv tryed flying with ai off as mentioned in the link to the article and all my problems regarding the degrading fps are solved a rock solid 45 fps for 3 hours or so thats all that i changed,
so a massive thank you for pointing that out @Manwith Noname.

I use some old hardware a i7 2600k and a GTX 1060 6GB. When the game launched CPU usage was low and GPU usage was also pretty low around 60% medium setting and a lot of stutter. For me the updates have improved the game. Now the CPU still isn't pushed but the gpu is hitting upto 99% and the settings I have bumped up medium upto high for clouds and increase level of detail. The recent updates have improved performance for me.

i had same issue, the game cant handle overclocked gpus

No problem. There are a number of ways you can deal with this but at least it helps somewhat.

That depends. It's not directly an overclock that causes issues but an overclock which is stable in some conditions might not be stable in others.

.... if you're CPU limited.

I'm pretty sure everyone is CPU limited. I'm running a 10900k and RTX3080 with 32GB RAM on Ultra @1440p. CPU utilization runs from ~16% to 24% and GPU ~35% to 50% yet Developer Mode shows me being Main Thread Limited. I assume that's because MSFS pounds a single core at or near 100% at all times.

The only remedy I see for this is DX12.

Don't get me wrong. I'm perfectly happy with the performance but I know it could be so much better.

Try your 10900K with a GTX770 (minimum required). Not a very likely scenario, I admit .. but maybe then you might not be CPU limited. ;-)

But yeah - DX12 might help, though the devs have stated they are not looking at using it for performance improvements, but rather for adding graphical features/effects. So, potentially, they may not change the underlying core engine to utilise the available threading that DX12 offers over DX11. We'll have to wait and see.

What do you have terrain and building LOD set to?

Everything is on full Ultra so they are at 200. I'm also using DSR at 2.0x but I still get ~45 - 80+ FPS depending on the area, altitude, etc.. I could try turning them down some to see if I get a graphical hit but that was really just a statement rather than a complaint.

[Manwith Noname]

Yeah, I get what you're saying, I'm just thinking of things that eat CPU with drawcalls.

dont use overclocked GPU it will bug the game and it wont use all ur rig capacity

in my case a little overclock brakes the game
My rig
core i9 9900k at 5 Ghz
Rtx 2080 super
32 Gigs ram at 4000 Mhz

Little point to overclocking the GPU if you're CPU limited anyway. However, in my case, I just run my machine with a slight overclock on both the CPU and GPU all the time. The game runs fine for me. If overclocking crashes the game, then it's your machine that's causing the crash, not the game. You've either gone too far or the machine just isn't suitable for overclocking (often cooling related, but not always).

Not always the case. I ran a 2600K oc to 4.6GHz for many years. Played every game just fine until I bought Far Cry 3. That game would crash every time until I lowered the CPU to stock clock. Not heat related either as I always monitored temps when overclocking.

I run something fairly close with dual 2080Ti's in NVLink mode and same CPU & memory.

I can overclock to 5ghz and it does not "break" the program, but the FPS does go down the toiler.

Monitoring the issue reveals that thermal throttling is to blame.... with good water cooling too.

Even one thermal throttle causes massive stuttering and fps drops.

You want to make sure it NEVER happens.

You are much better off keeping your CPU @ 4.8ghz for all cores than you are at trying to bump up one care to 5gHz.

Even though the sim is reported to be thread limited, all of your cores DO get used though not evenly.

With a more even response speed and avoiding thermal throttling you get much better results.
