New with ON1 PHOTO RAW 2020 we have made performance enhancements to better utilize higher end graphics cards. See below for a description of what these new features do.
*Video Card Strength — Balances updating the preview of the image and the movement of the the brush and gradient tools overlays. If your brush is sticking try turning it down. If you have a high-end video card try turning it up for faster preview updating.
* Fast Panning — Reduces the preview quality (makes it less sharp) while panning the photo to improve performance of panning.
* Fast Preview — Reduces the preview quality (makes it less sharp) while painting or making other adjustments to improve paint brush performance. This is off if you have a high-end video card.
* GPU Render — Uses the GPU (video card) to render preset thumbnails, exporting, printing, sharing and caching. This can greatly improve performance. It is on by default for systems that support it. It may be disabled on lower-end GPUs.
