I actually got Openxray (S.T.A.L.K.E.R: Call of Pripyat) running on the Pi 4 V3D driver. All I needed to do, after compiling from source, was use the below terminal command to force the OpenGL version to 4.1 and the GLSL version to 4.10. I am astonished it runs.

Code:
MESA_GL_VERSION_OVERRIDE=4.1 MESA_GLSL_VERSION_OVERRIDE=410 xr_3da
