My C++ programming skills are non-existant, so it was a bunch of fumbling around, but I was having issues with running out of texture memory on model imports that had a lot of small textures, so I bumped up the memory limits for that. I also ran into z-fighting texture flickering on large sized models when the camera was pulled out far, so I adjusted the precision amount to reduce that and got rid of most of the flicker. And then just a bunch of tweaks to increase weapon counts of ship systems and small stuff like that.
Nothing too major.
Mostly small little nagging things that I ran into.
