I’ve noticed some poor performance after a first scan that I’m trying to understand. My first scan runs well, between 40 and 50fps. I’ve done some somewhat long scans of 45k+ frames with no issue, utilizing 55gb of system RAM. However, when I close the first scan and begin a new scan the performance drops to ~10-15fps and doesn’t improve. Memory usage is 45gb at the start, so it doesn’t seem to be entirely unloading the previous session or something. I walked away from the software once while a scan was paused and returned to 74gb of RAM in use, so it seems to be doing something even when scanning is paused.
If I restart the software, it performs well again until a second scan.
This is on a Xeon E5-2696 v4 (22 cores, 44 threads) with 128GB RAM and a Quadro P4000 GPU that is not being used and running Revo Track 5.7.1 on Windows 10.
Hi! Thank you for your feedback. We will continue to optimize and improve the software’s performance. Currently, we recommend that you restart the software and create a new project scan.
Hi @jhov 45K of frames is considering a very big file compared to almost 4 regular scans.
I did not had that issue in the past while testing Trackit, but I never collected 45K of frames in one run either as I usually prefer small sections for better accuracy that was never bigger than 20K of frames . I will check it this weekend to see if I can recreate that issue myself .
It has more to do with the software and the system than the scanner itself and it is still improving like Gloria already said .
I will let you know if I can recreate this on my system.
I had no issues with capturing 80K+ frames. Things turned out great. I posted the images of the results elsewhere so I won’t post them here. I didn’t restart RT between scans. I did 2x scans of approx 80K frames and merged in RT. At no time was I seeing less than 45fps during scanning.
FWIW, I don’t run other applications during scanning (only RT). I take the time to clean up the process list on any computer I use (permanently disable background services that are not required to operate the computer). That saves processing power, and cuts down on software conflict. I’ve seen new laptops running 150+ background processes as delivered.

I still need to test it further, but I did two smaller scans in a row yesterday which did not have this performance issue. I think the difference is whether I complete the scan then create a new one, or if I cancel it to start a new one. When canceling the scan or returning to the main menu to start a new scan, I get poor performance. And not all scans are 45k+ frames, I was just giving an example to illustrate that it doesn’t appear to be related to the size of the first scan. I get the issue if I scan 100 frames and cancel to start a new one, but can also scan 45k+ frames in the first scan with no issues.
Hi @jhov you the first person that I notice having that issue , so until the problem is not duplicated there will be no solution .
I scanned many scans in the same project, pause it, start over and not once I have my frames dropped to 10fos , actually not at all .
So it is hard to put a finger on a specific issue here.
Anyway I will contact the technician on Monday and see if they can make appointment with you to see what is going on after checking the logs.
Another data point.. I bought a laptop for use with the Trackit to keep it a bit more mobile and I don’t have the issue with performance when using it. I just got it so I’ve only done some small test scans, but so far it performs the same scan after scan on the laptop.
