I recognized very poor performance with ON1 2019.1 and extremely high CPU load on my laptop with two graphic cards inside, an Intel 4700 HQ and a 4GB GeForce GTX 850M, both on motherboard.
My notbook: Asus i7-4700HQ, 16GB RAM, 256 GB SSD, 4GB GeForce GTX 850M
First step was, to uninstall some actual window patches. It seems, that ON1 works better, but not quit good as before. And, the updates are back, after some time of running.
Second step: i found this article:
After the GPU-configurations (Manage 3D Settings) from this article, i could observing, ON1 now uses the Nvidea GPU in photo processes, but zooming and moving within a photo, blocked the notebook for minutes.
Next step: i added the following programs, found in the windows ON1 folder, to use the Nvidea GPU too (via Manage 3D Settings):
on1capture.exe and on1sandbox.exe
After a fresh restart from ON1, almost of the full performance is back. Zooming and moving is still fast working. It seems, that there is more program code, that do not uses the Nvidea GPU and instead, the normal CPU or lame Intel GPU
Hope this experience helps ON1 windows users.
