    Updated : In cause you are experiencing a freeze while loading the game

    UPDATE : LOADING PROBLEM HAS BEEN FIXED When loading the game you can experience a freeze. The is not crashing just loading a big amount of textures that are used as monitor animations. It was created to reduce the CPU usage. Right now i am working on a visual loading system that will show you the loading progress. So don't panic when you hit 100% loaded and you wait some time till the game start.

    Update 1.7.6 additional fixes and changes

    Fixes : - Fix the grass rendering in the rover mode and storm the ares, Now shouldn't be rendered white or missing Changes: - Rover now uses a rigid body as a simulation instead of raytracing. This will help detects the environment better. - All prerendered textures for BOINC, antenna animations, etc. are implemented in the game. With this technique the CPU usage will be decreased, especially using the BOINC. The only downfall will be the increased loading time before starting a new game ( as some of you have already found ).

    Update 1.7.6 small update

    Fix: When using the VHS, the game starts filling the log file with thousands of unnecessary logs. Vegetation scale in distance Optimizations: In the old version the monitor antennas, planets when you detect signals and other animated monitor images were rendered in realtime as textures increasing the CPU usage. I have started to prerender some of the animations as separate textures, removing the camera rendering. The downside of this is a little more Ram usage and loading time, but this will decrease the CPU usage. In the next few weeks expect updates that will replace the old system.
