I'm still waiting to start my new job so spent 5 hours today updating to v1.1
There are some big changes in v1.1 over v1.0. There is now a config.txt file that once setup per installation instructions will execute console commands upon launch. These are tweaks and adjustments to prevent in-game setting conflicting with the mod.
Secondly, there has been an overhaul to the HDR so the extremes shouldn't be so bright/dark as many users commented. The difficulty with tweaking this game is that you need to be able to show bright desert, shadowy plains and lush jungle in the viewable spectrum of light. I was able to make tweaks through SweetFX to shadow gamma that allowed me to keep the mod colourful and bright during the day but lift the darkness of the shadows and indoors. Also, the desert should not be blindingly bright anymore - still bright but you should be able to see where you are going!
Let me know thoughts!
