CPU Utilization and Memory Utilization

We wanted to just perform a quick check on how well it is utilizing our AMD Ryzen 9 3900X, and anything else that was interesting to system resources.  We just simply utilized Task Manager System Performance to take a screenshot at various points of our flight to see CPU utilization, memory utilization, and also used GPUz to look at VRAM usage.

This run is the same Atlanta to Dekalb run we did on the previous page, with the same weather settings and plane settings.

Taking Off

The screenshot of the game included is exactly where we took this screenshot of Task Manager Performance as well, so you can see what we were looking at.  In the CPU utilization part of this, it seems to be using many of our cores during take-off.  CPU utilization was at 35% here.  However, we did see CPU utilization spikes as high as 56% from our CPU during the entire run.  The GPU isn’t being hit as hard during take-off, indicating CPU must be affecting on-ground, airport performance.  The SSD was getting hit hard during load but was not accessed much during the flight.  Memory utilization though rose very high at load, up to 98% of my total 16GB of memory!

After Take Off

This is after taking off, as we are starting to climb.  This shows you a spike of CPU up to 54% here!  Memory utilization is also starting to rise again.  SSD isn’t doing much, GPU utilization is starting to rise, and Ethernet is starting to rise.

Cruising

This is just cruising on our way to the other airport, at about 3240 feet.  CPU utilization has stabilized down into the 20’s of percentage.  However, memory utilization has rose sky high and GPU is now up to its full potential.  Ethernet is also getting hit hard.

GPUz

GPUz shows that 11058 MB of our total 11264 MB of VRAM is being utilized!  That’s all of it man, it is using it all.

Summary

The summary here is surprising, we didn’t expect RAM utilization to be as high as it was.  Our 16GB was saturated, we need more RAM for this game.  It’s clear 32GB of RAM would be a good upgrade for this game to help it run smoother, 16GB just ain’t cutting it at 4K with maximum settings.

We also note that CPU utilization generally while cruising is between 20-30%, but it can spike up to above 50% during loading and during take-offs. 

GPU utilization doesn’t hit its max until we take-off, and then our total of 11GB of VRAM was full, this game eats ram for breakfast.

  1. I was impressed by the promo videos, but not by the actual product. It doesn’t look nearly as good. My biggest disappointment is the ai generated terrain. It’s awful. I loaded up a city I know, I expected much better, most buildings doesn’t have the right shape or even their height I’ve seen a lot of multi storey buildings that were just one level here. And they didn’t even try to use real world textures. All the buildings in the entire city use the same brownish grey canned texture, which makes it look a kind of north korea, zero variation, zero color. Then there are rivers flowing over bridges. And cars drive underwater, where there is no bridge, cars that seem giant compared to everything else. And the bing aerial imagery is just very lowres and misaligned for the most part. Google earth’s ai generated 3D terrain is 100 times closer to reality. I’d actually prefer to fly over that to this. I was struggling to get my bearings things are so off. Plus I noticed a lot of fake light sources just floating in the air, not attached to a building or a light pole.

    As for the performance it seemed good enough for me, I definitely didn’t notice drops to 10 fps, I played at 3840×1600, but also have 32GB of ram.
    But this is the type of game where low fps is not that big of an issue to me.

  2. I do agree with you on the terrain, I have noticed it can look low quality at times when it really shouldn’t.

    I also wish they had used Google Maps, but it’s Microsoft, they have to try and make it look like Bing is worth it.

    Have you tried the game with 32GB to see how it affects performance?

    How long before someone makes a mod that uses Google Maps instead of Bing though?

  5. I’d guess: Never? You can’t extract actual raw data from google earth. Only map tiles as 2D images.

    Oh I did not know that. I definitely assumed that data was available for download. Seems if Microsoft allows or has that ability they got something on Google Maps/Earth.

    Well, there are things you can do when you own the service that aren’t necessarily offered to everyone…

    I thought about that, too. Though, it seems a lot of the data is entered by a third party person. I seen an article that had a 212 story building in the Sim that was only supposed to be 2 stories tall. Turns out, someone who was entering data for a University project had a typo and entered 212 instead of 2.

    While that doesn’t mean anyone can, it does seem to lean towards it being more open than Google Earth possibly.

    MS used an outside contractor to do the world terrain: blackshark.ai. I bet they used various databases and the kitchen sink to fill in all the blanks, and then used ai to fill what was still missing. It is safe to say they didn’t use the best data available, just what they could get their hands on for cheap or free. So university project falls right into that.

  10. Seen over 20gb of system ram usage on TR 3760x system with 64gb and 1080 Ti. 1080 Ti was using around 9.8gb average. 1440p Ultra settings

    For 16gb Ryzen 2700x system with Radeon FE, 11gb-12gb for system ram and over 15gb at times on the Radeon FE. Looks like the game can use the vram if you have it if the system memory is restrictive. 3440x1440p Ultra settings.

    The 5700 XT AE system with 32gb of ram, Ryzen 3900x, 19gb-20gb system ram and up to 7.8gb vram. Radeon 5700 XT AE has issues flying around the San Francisco/Oakland area with frame time spikes going up to close to 200ns. Other areas or locations so far are OK. 1440p Ultra settings.

    Brent please compare 32gb to 16gb system memory if you can update your computer.
