Logos Atlas has does not use GPU. Causing tremendous lag

Hello, the Logos Atlas tool works well on the web browser, and even works fine on my phone. However, using the Logos Atlas app on PC causes a massive slowdown and lag. It seems this may be due to the app not utilizing the GPU. This makes it entirely unusable on PC.

While the web app is usable it would be excellent to have this tool working in the desktop application.

Hardware acceleration enabled/disabled does not make a difference in performance.

Hi Elijah,

I'm sorry you are experiencing issues with the Atlas tool. We have been unable to reproduce this on our end, we would love to grab your logs to see if they can give us a bit more explanation. Instructions for grabbing your logs can be found here: How to Enable and Submit Logs

If you need another computer for reference in eliminating hardware issues, my Atlas tool is a little clunky but I haven't seen problems like the OP described. I have no idea whether it's using the GPU or the rest of it is good enough. My specs are in my signature.

provide hardware specs (CPU/memory, SSD or HDD and separate GPU) so we can assess what PC performance you have.

With a one year old gaming laptop i5, Atlas is more responsive than my 4 year old non-gaming laptop i5, but the latter is slow-ish as opposed to your description of performance. Both have an SSD. They have Windows 11 and 10 respectively, and run Logos on the internal GPU (described as GPU 0 in Task Manager). GPU 1 would be the external GPU.

Above are the Log Files. I simply opened the Atlas tool, moved around the map, and clicked a couple of maps from the left panel.

Below are my Specs:

Additionally, I have also attached here a screen shot of the task manager when actively using the logos tool. Yikes [:|]

It appears to be CPU limited. I get "Very High" for abt. 60% peak CPU, but don't max the gamer CPU.

From hardware info you have a more powerful CPU and 2x the memory of my non-gaming laptop.

I hope that Logos is not installed on the pure SATA drive as it should be on the larger SSD (it uses the same SATA interface which can be 4x slower than my PCIe interface). So which disk is the C:\ drive and where is Logos installed?

I can't be sure from logs what events determine the observed output lag, but your software takes 32s vs 12s to cover the same events related to Atlas (I've yet to do this on my non-gaming laptop).

Logos is installed on the larger SSD, not the HDD.

The install location is as such: E:\Logos

Windows is installed on the C:\ drive

As usual there is also a logos folder within C:\AppData\Local\Logos

The C:\ has atleast 8Gb free, and the E:\ atleast 800Gb

My non-gaming laptop takes 10s vs 12s for the gaming laptop to cover the same events related to Atlas Which shows that those events don't relate closely to the observed output lag, because the non-gaming laptop took longer to display the map (it was acceptable and definitely not sluggish).

But your 32s indicates that the display could be much slower as you reported, but unexpected given that the 9th generation CPU is faster than my 8th generation non-gamer (or standard laptop).

So it is not a Logos/Verbum problem.

I should even elaborate further. Under the inspection of the resource monitor, the Atlas helper process (listed as LogosCEF) uses as much as 70-80% of the CPU, pushing its total usage past 132%.

This usage spike only occurs when I begin to navigate the map. Once I stop moving around the map (i.e don't touch anything) the utilization drops back down to 0%.
