Version 1.4.4 is now live. No huge changes, just a few minor bug fixes and a new game config that can be accessed from the graphics option menu.
The new config is called STANDARD_BETTER.cfg. It uses higher polygon models for the environment and has higher resolution shadows. It's better than STANDARD.cfg but not as demanding as STANDARD_HI_SPEC.cfg, and should run well on cards as good or better than an nVidia GTX 970.
If you don't really care about the environment models or shadow quality, STANDARD.cfg will load maps slighty faster and has a faster frame rate.
