## Advanced graphics rendering disabled on featool startup

 >> featool Starting FEATool Multiphysics. Please be patient as loading all functionality can take a minute... Warning: MATLAB has disabled some advanced graphics rendering features by switching to software OpenGL. For more information, click here. I've been getting this message since I began evaluating FEAtool using the standalone version 1.11.  Now that I have Matlab and an upgraded version of FEAtool (1.12) I want to find out why. I followed the link ('click here', above) and wound up finding and executing the following: >> surf(peaks) >> ax = gca; >> info = rendererinfo(ax) info = struct with fields: GraphicsRenderer: 'OpenGL Software' Vendor: 'Microsoft Corporation' Version: '1.1.0' RendererDevice: 'GDI Generic' Details: [1×1 struct] >> info.Details ans = struct with fields: HardwareSupportLevel: 'None' SupportsDepthPeelTransparency: 0 SupportsAlignVertexCenters: 0 SupportsGraphicsSmoothing: 0 MaxTextureSize: 1024 MaxFrameBufferSize: 0 >> Here is the summary page of GLView for my system: I'd like to find out what it is bailing on.   Can you tell from this? Is there an output file or data object I can check to find out just what its complaint is with my system? Is this is check that FEAtool does explicitly or is done my Matlab on loading/calling some library/function? Kind regards, Randal
 Precise Simulation wrote The issue is most likely a mismatch between unsupported hardware (graphics card) and (Matlab or os) drivers/graphics libraries. ... (the error will most likely appear trying to plot or visualize anything in Matlab) You were quite right on both.  But after updating the NVIDIA driver, it seems happy! >> surf(peaks) >> featool Starting FEATool Multiphysics.

In any case, thanks for the diagnosis. -Randal
