Hi I'm trying to convert my siege ads to apex ads but am having trouble doing so my siege settings is 10/10/83 and 550 dpi I've also read that i should change my apex fov to 106.26 to match siege fov 90 better? currently my apex settings are at 2.6/.75 is the conversion below correct ? also how do i actually set my apex fov to 106.26
