i play with the optimization mod since the firs version and i have to say the done so many things, there found dozens of errors and endless searchings for files that doesn't exist and rebuild many of the ships with less polygons but the ships looks the same i would highly recommend to use there work at least for the coding and trade/refinery ships they also found may reasons why the game lag in the end even with the lowest settings for example your cpu have to calculate every fight even the ones you don't see, so its a cpu not gpu problem and mines are a biiiiiiiiig problem too, the ability of the mines searching ALL the time for enemy's, that means the cpu has to calculate on a middle map up to 1000 mine abilities so use the mod ore at least give it a look, i thing that would help very much to improve the game and the modding scene for the future as player you can simply activate the soage mod over the optimization mod it should change the things that stayed original like the trade ships
