GC III can't be very low level graphics-wise. My PC suffered since I have bought it five years ago from crashes due to (probably) graphics card overheating (although the measured temperatures were still in a reasonable area). That happened sporadically with all graphics intensive games after I played a while. So it happened with Skyrim, what is not surprising, but also with GC III, while games like Darkest Dungeon didn't have that problem.
I also had (and have on my notebook) the experience that GC III causes the fans to switch to higher rotation speed.
Now my graphics card died on Friday, so that problem is "solved" :/ Luckily I have also a gaming capable notebook to continue playing.
