 Although OpenGL ES has mechanisms to query the maximum number of samples (with a min of 4 on GLES 3.1), there&amp;#39;s no requirements for the opposite. Is there any expected behavior on Mali GPUs (at least from Midgard onwards and inclusive) if the amount</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: MSAA 2x on Mali - GLES</title><link>https://community.arm.com/thread/167549?ContentTypeID=1</link><pubDate>Fri, 18 Sep 2020 08:57:06 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:176cc537-1cad-4c71-b0ba-629c968df73b</guid><dc:creator>Peter Harris</dc:creator><description>&lt;p&gt;Hi JPJ,&lt;/p&gt;
&lt;p&gt;For OpenGL ES the implementation will round up to the next available size. Spec wording is along the lines of:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;&lt;span&gt;... samples represents a request for a desired minimum number of samples. ... the resulting value&amp;nbsp;&lt;/span&gt;&lt;span&gt;for TEXTURE_SAMPLES_EXT is guaranteed to be greater than or equal to &amp;quot;samples&amp;quot; and no more than&amp;nbsp;&lt;/span&gt;&lt;span&gt;the next larger sample count supported by the implementation.&lt;/span&gt;&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;&lt;span&gt;For Vulkan it&amp;#39;s undefined behavior, so you can&amp;#39;t really rely on it.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Cheers,&lt;/span&gt;&lt;/p&gt;
