In these contexts, frame rate may be used interchangeably with frame frequency and refresh rate, which are expressed in hertz. Additionally, in the context of computer graphics performance, FPS is the rate at which a system, particularly a GPU , is able to generate frames, and refresh rate is the frequency at which a display shows completed ...
On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown ().
Old menus on Windows 10 used 23p for 24 ÷ 1.001, just like 29 for 30 ÷ 1.001, 59p for 60 ÷ 1.001 and 119p for 120 ÷ 1.001. Integer frame rates were just 24, 30, 60, 120. This was corrected in Windows 10 20H2, where in new display settings menu actual 23.976, 29.970, 59.940 and 119.880 are used. [15]
FreeSync is an adaptive synchronization technology that allows LCD and OLED displays to support a variable refresh rate aimed at avoiding tearing and reducing stuttering caused by misalignment between the screen's refresh rate and the content's frame rate. [1] [2]
The advertised frame-rate of a specific display may refer to either the maximum number of content frames which may be displayed per second, or the number of times the display is refreshed in some way, irrespective of content. In the latter case, the actual presence or strength of any motion interpolation option may vary.
Microsoft Windows 95 and Windows 98 (First and Second Editions) set the refresh rate to the highest rate that they believe the display supports. Windows NT -based operating systems, such as Windows 2000 and its descendants Windows XP , Windows Vista and Windows 7 , set the default refresh rate to a conservative rate, usually 60 Hz.
The dynamic metadata are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way based on the content creator's intentions. HDR10+ is an alternative to Dolby Vision, which also uses dynamic metadata. [3] HDR10+ is the default variant of dynamic metadata as part of the HDMI 2.1 standard. [4]
This form of frame generation called Multi-Frame Generation is exclusive to the GeForce 50 series while the GeForce 40 series is limited to one interpolated frame per traditionally rendered frame. According to Nvidia, this technique will increase performance by up to 800% while retaining low latency with Nvidia Reflex. [29]
