＜Additional Graphics Settings＞
・You can now select the fps value from (30/60/Monitor Sync). Before this update, the fps value was determined based on your monitor. When using a monitor with a high refresh rate, this could increase the number of render passes and lead to higher GPU usage. This update sets the default fps value to 60.
・Render scale can now be selected from (50%/75%/100%). This option reduces rendering load by stretching and displaying content rendered at a lower resolution.
Other minor fixes have been implemented.
Update: Optimization_ver0.9.31
