Greetings. I did search the forums prior to this, and did not find any straight-up & simple answers. Just "turn it off to improve performance" kind of answers. Here we go: What do these options do? Quad Blending Gloss Mapping Particle Fidelity High Quality Cloth Fog checks per frame Concurrent Turns (have a slight clue, but need clarification) Also, when I run it in windowed mode, my video adapter and resolution in the options set to (null). It plays in a 800x600 window, but I'd like to play it at a larger resolution (1024x768). Are there more command lines I am unaware of? Thank you.
