I think it's important to try and maximise graphical possibilities in KSP2. The developers want to attract as many new players, and older ones who were put off by the last game, and by giving players with higher-tier gaming rigs the ability to really harness the potential for eye-candy will involve more people in the long run. We must also remind ourselves that as time goes by, we want KSP2 to age really well with the evolution of technology. So even if most people's computers cannot handle the higher graphical options today, that isn't to say they won't be able to handle them tomorrow. Let's not look back in regret and thank ourselves for pushing the capabilities of this wonderful game :)
