I admit it, I have only standard cooling for my CPU.
That said, I am noticing that no matter what settings I use graphically, this game often causes my CPU (i7 3770) to run at max, and temps regularly get over 100C.
at the same time, I only have what is now considered an average video card (Nvidia 760gtx), but even at high settings, it is only running that card at around 70%, and temps never get above 65C, which is about what I would expect.
it tells me a number of routines that could be handled by the graphics card (like physx routines) are being sent to the CPU instead.
Even enabling shader caching doesn't have much effect.
for optimization, especially given more modern rigs than mine, I highly recommend working on shifting more routines to be processed by the GPU instead of the CPU.
Hell, I can run Doom 2016 on high settings and it doesn't affect the CPU as much as this game does, and there are WAYYY more physical routines to process in that game than this one.
people are not going to want to buy a better than standard CPU cooler just to play this game.
just FYI, as I have always loved Larian studios for the attention to detail they give their games.
cheers.
