DOnt agree, original graphic looks best, imo and without bugs.
That is wonderful for you that you think the original graphics look best... no one ever took away that option... use what you like, don't force others to use an old muddy shader that has 50% of the frame rate. Not only are the old shaders worse, but you have to lower the graphics settings even further to get similar frame rates.
I understand that shader 3.0 is buggy. Buggy however is NOT unusable. Give us the option back and fix them when you fix them.
