Bottom line, it doesn't work nearly as well as the built-in Photos app in Win11, it had installation issues, and it maxes out some hardware resources. When I first tried to run SoftOrbits Background Remover an error message said msvcp140.dll was missing -- there are some Microsoft C/C++ runtime files in the program's folder, but not that one. Adding that file the software started. It also turned out that the installation routine had problems downloading the AI models it uses, maybe because of high traffic from being on GOTD? I originally had one model at 0KB, but after running setup 5 times I finally got deeplabv3_resnet101_coco.onnx at 70,719KB & MGMatting-DIM-100k.onnx at 4,543KB -- I have no idea if that's the correct setup or if there's more that's missing. Before I found the problem with the model files, I tried to use the app twice, & each time it locked up [crashed] Win11. With the model files in place it came close to locking up Windows -- move the mouse and after several seconds the cursor would stutter/jump -- but it eventually finished, with a Ryzen 5700G, 16GB RAM, & an RX 6600 graphics card. CPU use got to 90%+, spread evenly across all cores, it used up to 11GB RAM, didn't use the GPU at all [unlike every other AI app], and it took quite some time for a really poor result. In comparison using the same photo, the Photos app got near instant, and Usable results using the GPU, with Much less CPU & RAM.
The app itself takes up ~243MB in the default C:\Users\ [UserName]\ AppData\ Roaming\ SoftOrbits\ folder, with 2 files for uninstall in Program Files (x86)\ SoftOrbits\. The registry gets a couple of uninstall keys and one key for the app itself.
