Yes I am running Windows 10 and that video didn't fix the graphical bugs. It sucks because I really enjoyed the map, managed to get to round 15 before a big red square covered my whole screen and died.

Thanks anyway.

So I launch the map without Specular map on, but the textures are so buggy for me and when I enable Specular map on while in-game the textures are bugging out like it's impossible to play. Guns and objects are bugging out.

Is there any information on how I can fix this? I've done all the steps correctly.
