*Screen Settings*


| VR Emulation | The value indicating the current VR emulation mode. The FoV value in any selected mode is 110. One of the following values: - Disabled (by default) - HTC Vive (1512x1680) - HTC Vive Pro (2016x2240) - HTC Vive Pro 2 (3428x3428) - HTC Vive Focus 3(3428x3428) - HTC Vive Focus Vision (3428x3428) - HTC Vive XR Elite (1920x1920) - Oculus Rift (1332x1586) - Quest 2 (2712x2746) - Quest 3S VR (2712x2746) - Quest 3 (2064x2242) - Quest Pro (1800x1950) - Pico 4 (2160x2160) - Valve Index (2016x2240) - Varjo VR-3 (2880x2720) - Varjo VR-4 (3840x3744) `Console access:render_vr_emulation` ([API control](../../../../api/library/rendering/class.render_cpp.md#render_vr_emulation)) |
|---|---|
| Viewport Mode | The viewport rendering mode. The following modes are available: - *Default* - default rendering mode. - *Curved Panorama 180* - 180-degree panorama with curved edges. - *Curved Panorama 360* - 360-degree panorama with curved edges. - *Linear Panorama 180* - 180-degree linear panorama without distortion at the edges. - *Linear Panorama 360* - 360-degree linear panorama without distortion at the edges. - *Panorama Fisheye Orthographic* - orthographic spherical panorama (fisheye) with an adjustable Field of View. - *Panorama Fisheye Equidistant* - equidistant (tru-theta or f-theta) spherical panorama (fisheye) with an adjustable Field of View. - *Panorama Fisheye Stereographic* - stereographic spherical panorama (fisheye) with an adjustable Field of View. - *Panorama Fisheye Equisolid* - equisolid (equal-area) spherical panorama (fisheye) with an adjustable Field of View. - *Panorama Fisheye Kannala-Brandt* - Kannala-Brandt fisheye camera model. - *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. > **Notice:** If the panoramic rendering is enabled, underwater shafts and water line effects will be disabled. Option **#1** is selected by default (see above). `Console access:render_viewport_mode` ([API control](../../../../api/library/rendering/class.render_cpp.md#render_viewport_mode)) |
| Panorama Fisheye Fov | The Field of View (in degrees) for the panoramic viewport mode selected at the moment. > **Notice:** Available only when the viewport rendering mode*[ViewportMode](#render_viewport_mode)* is set to one of the fisheye panorama modes (5-8). Range of values: **[0, 360]**. The default value is : **0**. `Console access:render_panorama_fisheye_fov` ([API control](../../../../api/library/rendering/class.render_cpp.md#render_panorama_fisheye_fov)) |
| 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. |
| VSync | Toggles the vertical synchronization on and off. |
| Max FPS | The maximum FPS value, to which rendering FPS is to be clamped. 0 - disables FPS clamping. Both [VSync](../../../../code/fundamentals/execution_sequence/index.md#waiting_gpu), and *Max FPS* are actually about an additional idle period at the end of the frame. In case of *VSync* the Engine shall wait for the monitor to draw the whole image, while *Max FPS* enables you to specify any value for the delay (even a fractional, like 24.5). This clamping limit can be used for both debugging purposes and in the final build as well enabling you to smooth an unstable "jigsaw" framerate. For example, in case FPS jumps between 45 and 90, setting *Max FPS* to 45 may significantly improve your application's response visually. Range of values: **[0.0f, inf]**. The default value is : **0.0f**. `Console access:render_max_fps` ([API control](../../../../api/library/rendering/class.render_cpp.md#render_max_fps)) |
| 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. |
