Graphics Settings

Hey guys, I’ve been messing around with the graphics for a bit and I don’t understand some of the terms.
Since this game is horribly optimized (hence why it’s an alpha), I need to lower my graphics. My game manages to heat up my GPU up to 79 celcius.
Blend weights, shadow projection, shadow cascades, LOD Bias and all that. What are the best options for these to receive the lowest load?

I’ve been reading the forums extensivley and I have seen nothing on this at all. Let us know of the results of any testing you do, would be good to know

?

Throwing this out there, but I’m sure LOD means level of detail (so the lower, the faster). I’m not 100% sure though.
