Screen

This section contains screen settings such as VR emulation and stereo modes, virtual resolution, border, framerate stabilization etc.

Screen settings

Screen Settings

VR Emulation	VR emulation mode: Disabled — no VR emulation. HTC Vive — HTC Vive emulation. HTC Vive Pro — HTC Vive Pro emulation. Oculus Rift — Oculus Rift emulation.
Stereo	Stereo rendering mode: Disabled — stereo rendering disabled. Anaglyph — stereo mode that is viewed with red-cyan anaglyph glasses. Interlaced — stereo mode that is used with interlaced stereo monitors and polarized 3D glasses. Horizontal — horizontal stereo mode. Vertical — vertical stereo mode.
Panorama	Panorama rendering mode: Disabled — stereo rendering disabled. Curved Panorama 180 — 180-degree panorama with curved edges. Linear Panorama 180 — 180-degree linear panorama without distortion at the edges. Fisheye Panorama 180 — 180-degree spherical panorama (fisheye). Curved Panorama 360 — 360-degree panorama with curved edges. Linear Panorama 360 — 360-degree linear panorama without distortion at the edges. Fisheye Panorama 360 — 360-degree spherical panorama (fisheye).
Border Width	Width of the image border (in pixels), to be rendered outside the horizontal bounds of the screen to reduce artefacts of post effects.
Border Height	Height of the image border (in pixels), to be rendered outside the vertical bounds of the screen to reduce artefacts of post effects.
Max FPS	Enables clamping of maximum FPS to the specified value.
Virtual Resolution Width	Width of the virtual screen (in pixels). This option can be used to render video with high resolution (e.g. 8K) regardless of monitor's resolution.
Virtual Resolution Height	Height of the virtual screen (in pixels). This option can be used to render video with high resolution (e.g. 8K) regardless of monitor's resolution.

FPS Stabilization#

This feature is used to avoid significant FPS fluctuations making the frame rate smoother and driver's behavior more predictable, but for a performance cost (it may cause up to 30 percent FPS reduction).

The framerate stabilization feature reduces and smoothens actual FPS values higher than Min according to the following formula:

Stabilized_FPS = Rounding * floor( (Actual_FPS - Offset) / Rounding )

Notice

In case maximum render FPS clamping is enabled (see the render_max_fps colsole command), the resulting FPS will be equal to min( max_fps_value, Stabilized_FPS )

Enable	Toggles FPS stabilization feature on and off.
Speed Up	Number of frames per second for gradual FPS increase. This value controls smooth transition between various framerates and avoid fluctuations.
Speed Down	Number of frames per second for gradual FPS decrease. This value controls smooth transition between various framerates and avoid fluctuations.
Min	Minimum FPS value for which stabilization is to be performed. Notice For lower FPS values stabilization will be disabled.
Rounding	Determines unit size (granularity) used for FPS stabilization. Resulting FPS value will be rounded to the nearest multiple of the unit size.
Offset	Amount of actual FPS reduction used for stabilization, in frames per second. Actual FPS value will be reduced by this amount: Resulting_FPS = Actual_FPS - Offset
