lol, support for opengl 3.3 started with 10xx series video cards, and laptop mx150. luckily my 3070ti supports opengl version 4.6 ))))
OpenGL 3.3 is a bit old yes, it was released in 2010 I think. After some research, it seems the last version of the engine did not update the OpenGL driver, it was already 3.3 on the previous version, but it added a compatibility layer driver called ANGLE. There is a list of 66 graphics cards in the engine where ANGLE is enabled by default so it might be the case that older hardware will have an incompatibility error because of this. I’m not sure however as I’m just speculating based on what I found.
Still, I think even if the graphics cards are from before 2010, as long as there is a driver update to add OpenGL 3.3 support, it should work :).
