Temporary CPU spikes in cruise

[xkoote 57]

Hello, 

I wonder if some more knowledgeable can shed some light on this. The specs are:

Z490 Taichi - i9 -11900K no OC - Nvidia 3080 Ti - 16 Gb DDR4 4400 Mhz

I play 5.3 with Volanta, ChasePlane and ActiveSky P3D running on the PC. vPilot runs in host mode. My laptop has it as remote with voice.

I have very little knowledge of Affinity Masking. According to some forum posts that mentioned to mask logical processors 0, 1 and 2, I tried the following setting:

[JobScheduler]
AffinityMask=1048575
P3DCoreAffinityMask=1048533
MainThreadScheduler=0
RenderThreadScheduler=2
FrameWorkerThreadScheduler=4

However, with 5.2 and no masking, I had the same issue. This happens while in cruise. Around big airports with a lot of dynamic lights, my frames struggle a bit, but that is another matter. Every 4-10 minutes, the CPU load and temperature spike for a few seconds, then settle back down. 4 to 10 minutes later, it goes off again. Below is the performance graph and the processes while spiking. And the rest normal state when not spiking.

 

Spike observed across basically all processors

Processes when spike is occurring

 

Processes when the sim is running normally the other 99% of the time. P5D cycles between 12% - 28% CPU load

 

Do any of you know what could be causing these momentary spikes? Normally I find it not an issue, however I don't like the fact that these spikes cause in-sim stutters. These stutters also cause a slight loss in sim time. To the tune of 1 minute over a long haul flight. This wasn't the case back prior to 5.1 or 5.2 I think.

 

Thanks,

 

Xander

     I notice the spikes when some distant scenery, such as mountainous terrain is being drawn. When complete the spikes go away and the CPU usage drops way down.

I'll try and pay attention on the region. Thanks....
