CPU 100% and app crashes on approach

Post by azwildk4t »

I am having a nasty issue trying to complete flights with P3Dv4.4. I noticed my CPUs are all pegged at 100%. My setup has 3 computers of which an ASUS computer is the main flight sim system. The other 2 support ProSim Displays for FO and CDUs.

The ASUS system has an i7 chip with 8 CPUs and a Nvidia GTX 1080 GPU. I looked at task manager and found that P3D consumes 50% and Prosim another 36%.

Here's the breakdown:
P3D = 50.1%
ProSim System = 12%
Prosim Display = 9.2%
Prosim Display = 9.8%
Prosim MCP = 5%

Any recommendations how i can tweak my system to move more to the GPU?

What is the GPU utilization? Also it would be useful to provide the full pc specs so that we can determine where the bottleneck is.
PC Specs - Intel Core i7-9700K, Asus ROG Strix Z390-I Gaming, 32GB Corsair Dominator DDR4, Asus GTX 1080 Ti Strix, 2x Samsung 970 NVMe RAID 0, WD Black 1TB HDD, Samsung CF791 Ultrawide, Windows 10 Pro 64-bit.

Thanks for the reply.

My PCs specs are:
  • Intel i7-6700k @3.4Ghz.
  • 16MB RAM
  • SSD drive
  • 1TB HDD
  • Nvidia 1080ti graphics card
  • Windows 10 Home 64-bit
I'll need to check on GPU utilization.

First step when encountering a crash is to ask windows what happened by using the start button and typing problem reports. Look for P3D reports, and you want to know what the faulting module was. No system is going to crash because the CPU is at 100%, going after utilization is a red herring.

As a footnote, my GPU is only at 17%.

Is there any settings that can reduce the load on CPU and move more use of the GPU?

Sorry, this is a bit OT.

6700K at 3.4 GHZ?

Why don't you overclock this processor? The 6700K can be a very good performer and there are many success story's in overclocking this processor.

Thanks Arthur. I've never done that but let me look at some videos on how to do it.

That is good advice but not a solution to your problem, which is caused by tmmon64.dll. Google it and half the world has problems with this module added by Trend Micro software. This is an AV addon causing your problem. Get rid of it in my opinion. Windows Defender works and it's free.

I didn't realize that. I removed Trend Micro awhile back when I was having issues and then had it added back in when I had my PC serviced by Data Doctors. I wish there was a disable mode while running the sim. I'll uninstall and give it a try again.
