+NVIDIA optimus systems will default to intel integrated graphics chips.
+These chips cause fatal memory issues when using opengl3.3 (even though they claim to generate correct contexts)
+
+This export gets picked up by NVIDIA drivers (v 302+).
+It will force usage of the dedicated video device in the machine, which likely has full coverage of 3.3
