<member name="rendering/gl_compatibility/item_buffer_size" type="int" setter="" getter="" default="16384">
Maximum number of canvas items commands that can be drawn in a single viewport update. If more render commands are issued they will be ignored. Decreasing this limit may improve performance on bandwidth limited devices. Increase this limit if you find that not all objects are being drawn in a frame.
</member>
<member name="rendering/gl_compatibility/nvidia_disable_threaded_optimization" type="bool" setter="" getter="" default="true">
If [code]true[/code], disables the threaded optimization feature from the NVIDIA drivers, which are known to cause stuttering in most OpenGL applications.
[b]Note:[/b] This setting only works on Windows, as threaded optimization is disabled by default on other platforms.
</member>
<member name="rendering/global_illumination/gi/use_half_resolution" type="bool" setter="" getter="" default="false">
If [code]true[/code], renders [VoxelGI] and SDFGI ([member Environment.sdfgi_enabled]) buffers at halved resolution (e.g. 960×540 when the viewport size is 1920×1080). This improves performance significantly when VoxelGI or SDFGI is enabled, at the cost of artifacts that may be visible on polygon edges. The loss in quality becomes less noticeable as the viewport resolution increases. [LightmapGI] rendering is not affected by this setting.
[b]Note:[/b] This property is only read when the project starts. To set half-resolution GI at run-time, call [method RenderingServer.gi_set_use_half_resolution] instead.
