I'm having problems with the lightning in this mod. My screen spazes out whenever there is lightning. Two things went through my head: maybe fps is dropping below 30 fps or maybe my monitor can't refresh fast enough to display it properly. I don't think it's my monitor since it has a 3ms refresh rate. I uses rs_stats on and saw that fps did drop below 30 on lightning. I turned settings down to medium and still had the same problem. Even though fps never went below 30 my screen still spazes out. Not sure what the problem is here. I tried to find the author for this mod but it seems he's no longer registered.

Hello.
Sorry for the late reply, hope it´s still gone help you.
The flickering is a "bug" in this version, and it has nothing to do with your hardware.

I could not eradicate it totality in this version but a way to smooth it is to use the user.ltx file provided in the download.
You also can use some of the settings of with if you dont´want to use it all.
