When trying to run X Plane 11 demo I get the following error message:- "Problem processing a GLSL pixel shader".

I have reinstalled and run an update but I still get the error message.

X Plane 10 runs OK on my system.

My system appears to meet the minimum requirements for X Plane 11

Extract From Log:-

0:01:15.453 E/SYS: +-------------------------------------------------------------------------------
0:01:15.453 E/SYS: | There was a problem processing a GLSL pixel shader.
0:01:15.453 E/SYS: | You may need to rerun the installer or update your graphics drivers.

0:01:15.453 E/SYS: | Resources/shaders/blit.glsl
0:01:15.453 E/SYS: | (OGL_shader.cpp:781)

There are no further updates for my graphics drivers.


Can anyone confirm, please, whether this error could be a compatibility issue with my system or there is another issue?

According to XPlane suppport my system did not meet X-Plane 11 minimum requirements. Apparently my graphics card is too old.

If you submit the log file to X Plane support, they should be able to provide a diagnosis

@Colourise  Thanks. I submitted the log already.

I have a GeForce 9800 GTX+ Series 9.  The system requirements state NVidia Series 600 or newer.  Is the following card should be ok?

MSI GeForce GTX 970 Gaming 4G, 4GB GDDR5
