--- Comment #7 from haarp liquitsnake@gmx.net 2008-06-28 16:04:59 --- LOD and Texture level always allowed for High settings, this is not news. This bug is NOT fixed. I confirmed that Fidelity still can only be set to Medium in 1.1.0.
On a related note, it seems that a few new effects seem to be working now in SupCom. Oh wonderful explosions!
