Doom+ is a Vanilla like shader with heavy improvements. It has water wobling, Rain effect, Snow effect, Costum Lighting thats close to vanilla (But improved ofcourse!)
Here is some example of the Shaders posibilitys:
A better Lighting without hurting too much performance,
Effects that is also in HUGE beautifull shaderpacks but it takes less things to run... (Adjustable too)
YOU CAN EVEN ADJUST YOUR SHADOWS GENTLEMEN!
This Shader can be ran on everything that can run the first Doom game,
Effects that look vanilla!
