Increased Accuracy Toggles increased accuracy of ray tracing for the SSR effect on and off. This option reduces visual artifacts around objects, which can appear at low resolution (lower than full), by increasing accuracy of the last step.切换光线跟踪的准确性,以启用和禁用SSR效果。此选项通过提高最后一步的精度来减少对象周围的视觉伪像,这些伪像可能以低分辨率(低于完整分辨率)出现。
Fast Tracing Toggles fast tracing for the SSR effect on and off. This mode makes it possible to obtain distant reflections using low number of steps while keeping performance high.
