Hello.
I have recently discovered that some games have some sort of patch to trick the game into thinking that the game has a specific shader version.
For example I couldn't play TES 4: Oblivion because I didn't have good enough shaders.
But after downloading the patch oldblivion, it could be played on my (lower spec) shaders.
Does IV have anything like this? Because I don't have Vertex shader 2.0.
