Hi everyone, I have a major problem with my recently bought xplane11, after about 5-10 minutes from starting the game, the game has frame freezes about every minute. The freeze lasts from 2 to 15 seconds, and I don't know what causes this. I have a Nvidia driver and so I already tried to turn off Thread Optimisation but nothing changes. The framerate and these freezes don't change if I set the graphics settings to minimum or high so I really don't know what to do.
Here I give you my pc specs:

Cpu: Intel i7-6700hq
Gpu: Integrated Intel 530
Gpu: Dedicated Nvidia 950m
Ram: 8gb
Samsung SSD 850 evo 500gb

Edit: I noticed that this happens just when I start the engine(s). It doesn't matter which aircraft it is.

Hi, have you tried to delete (or move for backup) the whole X-plane 11/Output/Preferences folder?

Also make sure you have disabled shadows in X-plane graphic settings

I tried all this but nothing changes but I have seen thanks to the other answer that my CPU uses only 40-50% of its potential and sometimes the CPU has drops of performance down to 20%. Of the 8gb ram, the game uses 3.5gb and I have 1.9gb free so it's not a memory problem.Do you have some tips?

Hmm.. not yet unfortunately. Expect a better use of the CPU and GPU along the coming updates because Laminar Research is currently working a lot on optimisation.

I'm sure you've seen this already :

Have you tried hyperthreading on oandoff (i have it off) in your Nvidia settings?

Also, can you confirm this is a clean install of X-plane? If not, can you remove or disable your additional plugins and other addons, or even install a second clean copy of X-plane to see how it performs? You just need 10 Gb of disc space, and the installer will let you install a second copy. 1 licence = 1 instance of X-plane running at a time. That's the only restriction.

First of all, thanks for your fast answers.
It's a clean install of x plane 11 because I installed it 2 days ago for the first time. I didn't put plugins at the moment, it's 100% stock. I don't have seen the video on youtube yet, when I return home I'll try to see the video calmly and try to optimise the game for my pc. I'll let you know :)

So I tried every kind of settings based on what the youtube video said but I get the same amount of fps and everytime the same problem. I tried to update my gpu driver (my pc needs a specific old driver because of the double gpu) but it's even worse. The 950m gpu usage is 0% and x plane runs on the integrated graphics, so I returned on the old driver. I really don't know what to do.

Maybe you can try and go through this, see if you find any help in one of the topics...

Can you include your X-plane 11.log.txt ? It could help a lot, but I'm a bit stuck here. Maybe someone else (I am not from Laminar research) will understand what is happening.

Here's the log :)

I really thought about everything but not updating the gpu driver, so I updated it and it is still worse. Looks like x plane 11 runs on the integrated graphics now, it can't even reach 3 fps. Shouldn't the update bring more stability? It's the first time that I experience a better stability on an old driver.
commented by (3.5k points)
This has already happened to me. It's rare but possible, sometimes, to get better performance with an old driver. Usually the problem is solved with the next update.

Thank you a lot!

Not sure if this applies to Xplane; but in other games this freezing can often be traced to page faults -  whereby there is usually insufficient GPU memory or system memory... or both. The page fault history can be monitored in the (Win 10) Resource Monitor.

Thanks for the tip, I encountered a 40-50% of CPU usage and drops every 50 seconds to 20%. Do you know how to resolve it?
