Dreadful performance

Continuing the discussion from Dreadful performance:

Personally having bad performance will be fine for me… The main problem is those random crashes at any times. With Dev mode I can see I’m above 30-45 fps with rarely a drop at 25 when stuff load. cpu run at 75% on average and temperature on my gpu are fine.

I have i7 7700k
32 gig ram
rtx 2070.

running the game on medium or low (2560x1440p window mode because I don’t want to stretch it in full screen on my 4k wide monitor). On the first day I was on high setting / 4K and had the same amount of crashes or maybe less…

I do believe my 7 gen cpu is the problem but my motherboard can’t take 8gen and up, so I’m stuck with it for now.

Like many of you I just don’t know what to do at this point, I tried many solutions except moving the game to C drive I don’t have any space for it but the game is on a ssd right now, it should be fine.

UPDATE I fixed it mainly by stop using my Bluetooth keyboard and mouse, I couldn’t figure it out why i was getting freezes then crashes but yes indeed when i was using my keyboard after a long time, it was reconnecting and then crashing a bit after. Those Bluetooth surface peripheral always disconnect themselves from the pc unless we use it (save battery)

A lot of the crashes seem to be caused by USB and Bluetooth devices, when they connect/disconnect. So a few thing to try would be to disconnect any USB devices you don’t need and turn off Bluetooth if you don’t need it before starting the simulator. Also, you could try changing USB ports, and try not using any USB hubs, if possible. And don’t connect or disconnect any USB device while using the simulator. Also overclocking could cause some of the crashes.

But I feel probably just half of the crashes have hardware causes related causes, the rest are just plain simulator bugs. In fact, except for the overclocking caused crashes, the hardware triggered crashes are also bugs, the simulator shouldn’t crash when I connect an USB headset.

If it brings you any comfort my copy has been on the c drive from moment one and I’m still having a bad time, so you’re probably not missing anything that would help by not making that move.

Hi Guy maybe i found the solution !

Look this (is French but translate)

:J’ai pas vu explication de Morph, mais en gros les ports PCIe sont connectés au CPU de plusieurs façons : soit directement au CPU, soit en passant par le chipset de la carte mère (indiqué comme AMD B550 l’image que tu as envoyé):

I think we need to look this !!

That’s not a fix, it’s not even a suggestion but a statment of fact

“: I haven’t seen Morph’s explanation, but basically the PCIe ports are connected to the CPU in several ways: either directly to the CPU, or through the chipset of the motherboard (indicated as AMD B550 the image you have sent):”

Sorry, there the full message:

I haven’t seen Morph’s explanation, but basically the PCIe ports are connected to the CPU in several ways: either directly to the CPU, or through the motherboard chipset (indicated as AMD B550 the image you sent )

and therefore necessarily, if you go through the chipset before arriving at the CPU, it is not opti

So as a general rule, we place the graphics card in the highest PCIe x16 slot, usually the one directly linked to the CPU.

I’ve tried pretty much everything I’ve found in this forum. Nothing changes, nothing helped. I’m gonna try one setting in Nvidia drivers: Graphics stuttering, uneven framerate, broken immersion
and also I’ll try to OC my RAM to hopefully 2100MHz. Let’s see if that helps. I regret I don’t have a HT CPU as this gives hope for improvement. Many reported great results with enabling HT. This helps to lower CPU usage a bit

You can try doing this, it helped a lot for my 4690K:

Download something called Process Lasso, and while the game is running (Do this only after the game reaches the main menu), right click on the game’s process (FlightSimulator.exe), go to Priority Class -> Always and then disable “Windows dynamic thread priority boosts enabled (*)”.

I`ll try that and take it down to default CPU speed Thanks.

sorry im new to all this, but is this effectively my problem?

Yes, to confirm this turn on developer mode in MSFS settings, then select FPS. Load into an aircraft and see what the text says - Limited by GPU or Limited by Main Thread

Ok will try now where’s the option to turn on FPS?

Once Developer mode is turned there should be a black bar at the top, select options then display FPS

Yep thanks just loaded in and it says limited by GPU

Ok are you running with unlimited FPS?

How do I know? It’s running at 10/11 FPS

Graphics - VSync on or off?

It’s off right now

You could try turning it on? But don’t know if it will make much difference

Didn’t make any difference . When I screenshoted my Radeon page it showed GPU 1 at max but GPU 2 at nothing, could that help?
